#10 x 3 Inch Stainless Steel Deck Screws 350 Pieces | T25 Star Torx Drive Flat Head | 304 Grade...

Check Current Price

This product is manufactured at a level of durability which is appropriate for properly putting together your deck planks.

The package contains 350 pieces of 18-8 grade stainless steel screws. Due to their construction, the screws are particularly recommended by users of pressure.

Each screw has a #10 diameter with a length of 3-inches. It has a flattened head portion, which easily does the job of blending into your deck.

The drive style is a standard Torx (T25) drive, also known as a star drive. Therefore, it’s easy and quick to install. It also doesn’t cause screw-driver slippages during the process.

The head is sloped into the shank of the screw. This helps the screw-head to properly level with the ground while providing ground adherence.

The tip of the screw is a type-17 point tip. That means, it'll cause much fewer debris throw-outs compared to a type-A or type-B tip. Type-17 point tips are also great at reducing splitting issues while putting together planks.

Every screw of this package has an anti-corrosive coating and a nice, burnished look. So, if you own a deck that’s on a coastal area, which constantly deals with rust inducing elements like salt and water, these screws will be a perfect fit.

The package also includes a Torx drive bit for your extended comfort.

Highlighted Features:

2. SNUG SNG919 Tan Fence & Deck Screws

100 Qty #9 x 2-1/2' Inch Tan Fence & Deck Screws | Torx Star Drive | Bit Included (SNG919)

Check Current Price

Snug fasteners bring to market a simple yet effective product with the SNG919.

The package contains 100 pieces of stainless steel (305-grade) screws. These screws provide more adhesion strength and longevity than regular metal screws made of copper or zinc.

They are layered with an anti-corrosive coating to provide environmental flexibility. So, you can use them both as outdoor deck screws and for internal wood-related repairs.

Each screw is 2.5-inches long and has a #9 diameter. It’s designed with a bugle style head, which has a flat top with nibs sloping to meet the shank. This design helps the screw to sit in level with the deck by countersinking it.

The screws are manufactured with a standard T25 drive. Often generalized as a star drive, this drive system makes installation quick and safe by providing a fast torque and preventing cam-outs.

The shanks are partially threaded using a coarse style threading. This means, each screw has fewer threads per inch and the threads are formed larger than the screw’s diameter.

The threads are left-handed instead of right, which can be of great use to some users. The threads of each screw are sharp and self-cutting, which easily drives them into the planks.

The screws also come with a Torx (T25) drive installer bit. So, you won't need to waste time finding the right screwdriver to install them.

They are designed with a type-17 point tip which makes them self-drilling. Thus, you won’t need to make any pre-drilling holes either.

Highlighted Features:

  • The product contains 100 pieces of self-drilling screws.
  • It comes with a compatible Torx driver bit.
  • You won’t need to make pre-drilling holes to install decks using these screws.
  • The screws are manufactured with left-handed threading.
  • Designed with a bugle style head, the screws camouflage nicely into the deck.

Check Current Price

If you're looking for that sweet deal where ample quantity is provided without any compromise in the quality and burning a hole in your pocket, this is the product for you.

The product comes in a high-quality plastic container, equipped with a carrying handle. The container holds 700 stainless steel screws.

These go through a thermochemical heat treating, known as case hardening, for increasing their yield strength. Thus, these screws can provide superior holding strength when it comes to holding deck planks together.

The 2.625-inch long screws have a #8 diameter each. They are also coated with zinc to resist corrosion. This feature can be specifically helpful for installing decks in wet or salty areas. The screws are designed to install up to 2-inch long and 1.5-inch thick deck planks in a durable manner.

Each screw is designed with a flattened head and straightly sloped nibs. So, apart from providing a good amount of ground adhesion, it also manages to reduce the possibility of cracking the planks through installation.

The screws have a square style (KTX) Torx drive. This drive style lessens the spinning of the screw and slippage of the screwdriver, ensuring a quick and smooth installation. It also increases the driving power.

The shank is partially threaded. Its thread-less upper portion makes installing planks across the deck's joist easier and durable.

Each screw is manufactured with coarse style threading with an aggressive cut which will help you to drive them into the wood (specifically hardwood and pressure treated wood) with comfort and precision.

These self-drilling screws are custom made to work with Kreg’s deck jigs. They are colored in a neutral range which helps them to mix in with the deck. Each screw is also protected by a tri-layered patented (“Protec-Kote”) finish to resist corrosion caused by humidity, dampening, etc.

Highlighted Features:

4. Hillman 48419 Deck Screws (Pack of 310) 

Deck Plus 48419 Wood Screws #10 x 3', Tan, 5lb Box

Check Current Price

If you are concerned about corroded screws ruining your beautiful deck, this product can be your savior. Hillman Fasteners provides you 310 pieces of 305-grade stainless steel screws, which have one of the most advanced anti-corrosive coatings in the market.

The screws have a ceramic-brown colored coating that's consisted of 4 layers. First, they are layered with Zinc, then a second layer of chemicals for adhesion is applied. On top of the 2nd layer, you’ll get an epoxy coating that’s finally covered with a protective finish.

Since pressure treated woods contain a variety of chemicals to protect against erosion or infestation, they can often corrode ordinary deck screws. And if you have such a deck in a wet atmosphere then the chance of rusting and corrosion increases even more.

However, with such an advanced coating, these screws will perform at a superior level as deck screws for treated lumber decks, regardless of the weather. The coating has also passed the “1,000-hour salt spray" testing.

They are delivered in a transparent and reusable container with a user-friendly lid system in place. Each screw is 3-inches long and has a #10 diameter. They are designed with flat heads.

Manufactured with advanced countersinking nibs, the screw-heads meet a reinforced shank. The shank is partially coarse threaded and ends in a self-drilling type-17 point, equipped with a quick start feature.

This way the screws reduce plank splitting and save you the trouble of making any pre-drilling holes.

The screws have a specialized “no-strip star drive” system. Thus, you won’t face stripping, cam-out, or slippage issues. It’ll provide a faster torque and enhanced drive energy for smooth installation.

 The manufacturer also provides a compatible (T25) star drive bit with the package.

Highlighted Features:

How To Choose Deck Screws for Pressure Treated Wood?

Deck Screws Buying Guide

1. Level Of Camouflage

You must ensure the screws provide a high level of camouflage. Pressure treated wood planks are expensive due to their superior durability. However, if you choose screws that don't match the plank then you'll have an ugly looking deck despite all the expenses.

This issue can occur due to several reasons. For example, if the screw heads aren't level with the ground and stick out. It can also happen due to choosing screws coated/burnished with colors that contrast sharply with the wood planks.

Thus, ensuring that the screws smoothly mix in with the deck after installation should be one of your prime concerns.

2. Drive Type

It's important to choose screws with the proper drive type. This is because from installation to maintenance, the drive type of your deck screws will play an important role.

We recommend choosing modern and technically advance drives for your deck installing screws. For example, the Torx drive is universally known for providing quick installation, preventing cam-outs, and reducing the amount of dust, chips, and other debris.

In terms of maintenance, choosing a drive type with these qualities will help you. It'll allow you to quickly change, wash, or repair planks by providing a fast and reliable screw-out as well as a screw-in method.

3. Style Of The Tip

To provide ease of installation and preserving the structural integrity of your valued wooden planks, the tip of your screws requires a good amount of consideration.

Without the right tip or point, you’ll face difficulty in putting the planks together. A wrong choice in this matter can also split or crack your deck planks.

That’s why you need to ensure that your preferred screws have advanced engineered tips.

We recommend choosing a self-drilling tip as it’ll save you the trouble of making pre-drilling holes. However, you can also go for self-tapping tips, which won’t be as hassle-free as self-drilling tips but can provide more or less the same amount of benefit in avoiding cracking and splitting issues.

Various tips can aid you in this matter. For example, the type-17 point tip is generally held in high regard for deck screws, which is evident from its wide use in the industry.

4. Thread Count, Handedness, And Edge

Choosing screws with threads that are engineered to serve your particular purpose can be tricky.

Some wood planks work well with fine threads and a high thread count (measured by Thread Per Inch or Thread Pitch depending on the measurement system), while others are compatible with coarse threads.

Also, most threads are naturally angled right-handed. However, there are screws with left-handed threads, such as Snug Fasteners' SNG919.

In terms of edge, the best deck screws for pressure treated wood usually come with a sharp and serrated edge. Because, it makes driving the screws into the wood easy and fast, as well as increases their holding power.

5. Merging Amount And Quality

Deck screws are mostly sold in bulks, that is in a packaging that contains anywhere from 100 to 700 pieces. Thus, you can be overwhelmed by the quantity that comes at the cost of quality.

That's why we designed this guide to list products that'll give you the sweet spot between amount and quality.

Don't compromise on quality because this decision will have a larger impact on your deck's overall health. Instead, find the right balance between an economically beneficial amount and the overall quality of the screws.

6. Weather Resistance

A deck is by definition an outdoor installation. So, it’s always a good idea to make sure your deck screws can “weather the storm” so to speak.

That is, purchase deck screws that are equipped with weather-resistant features. We recommend buying high-grade stainless steel (e.g. 304, 305, 306, 18-8, etc.) screws as these will naturally protect against a variety of weather issues, such as corrosion.

Specifically, if you live in a humid area with daily rains or a seaside residence where salt and splashes of water are in regular contact with your deck, using weather-resistant screws will save you multiple repair and replacement costs.

7. Material Compatibility

We all have our unique choice of lumber while building a resident or commercial deck. Some like to use natural wood (e.g. softwood and hardwood), while others may go for a composite or pressure treated lumber deck.

Manufacturers often provide specialized screws for particular wood types. For example, WoodPro's CD10X212B-5 is intentionally designed for composite wood decks but may not be compatible with a softwood deck.

8. Strength Of Adhesion

Strength Of Adhesion

Since the structural integrity of your deck largely depends on how well the planks are connected between themselves, the strength of your deck screws in terms of adhesion is worth considering.

The strength depends on a variety of aspects that each screw of a particular product embodies. These include the raw material used in production, drive type, build of the shank, thread count, etc.

For example, screws with reinforced necks/shanks will have superior "strength of adhesion". Screws made from heat-treated stainless steel will be stronger than copper or other metal screws.

Frequently Asked Questions 

1. What is the Difference Between Self-Drilling And Self-Tapping Deck Screws?

Answer: A self-drilling deck screw doesn't require you to make any pre-drilling holes before using them. As you drive a self-drilling screw into the deck plank, it's designed to create its drilling hole through the process.

On the other hand, a self-tapping deck screw requires you to make a pre-drilling hole before usage.

However, they create less dust and debris during installation and provide more torque and driving power than regular deck screws.

2. What Kind Of Screws For Pressure Treated Wood Should I Use?

Answer: Pressure treated wood planks are stronger and provide better protection against erosion, infestation, dampening, and other quality degrading issues compared to untreated wooden planks.

However, due to their strong structural integrity and containment of various preservative chemicals, you'll need special types of screws for treated woods (which we’ve featured in this guide).

If you use regular screws with pressure treated wood, they may bend or slip and can become corroded by the preservative chemicals contained in the wood.

Thus, we recommend using 305 or 18-8 grade stainless steel screws with an advanced anti-corrosive coating, like the Hillman Fasteners' DeckPlus 48419 screws.

3. What is the Difference Between Screws for Treated Lumber And Screws For Pressure Treated Wood?

Answer: Practically speaking, there isn't much of a difference. Treated wood, lumber, planks, pressure treated wood, etc. are used as interchangeable terms in the industry.

However, technically speaking, treated lumber can mean any technique or technology that has been used to treat and upgrade a certain type of wood.

But pressure treated wood means, a specific technology, known as "pressure treatment" has been used to treat a particular batch of wood planks.

The technology uses a vacuum chamber to empty air pockets from a wooden plank, then floods the chamber with preservatives that are soaked into the plank.

4. Why is the Drive System Of A Deck Screw Important? 

Answer: The drive system of the deck screw largely determines the ease of installation.

For example, screws that use a Torx drive (e.g. T25) or a Robertson drive (e.g. #2 Robertson Drive) will provide increased driving power and torque compared to screws that use a Philips drive system.

A Torx or Robertson drive will also lessen stripping, splitting, and cam-out issues compared to older drive systems.

5. What Is A Self Countersinking Deck Screw?

Answer: A self-countersinking screw is designed with usually a flat head and countersinking nibs. These features automatically level the screw-head with the ground of the deck. Thus, you can install/repair a deck without distorting the texture of its surface.

6. What Is The “Holding Power” Of A Deck Screw?

Answer: The "holding power" of a screw, also known as "ground adherence", simply means how well a screw can connect or keep together different deck planks or lumbers.

Screws with higher holding power will have better tensile strength. They can increase the internal structural integrity of a deck better than screws with lower holding power or nails.

Final Word

Deck screws come in a variety of shapes and forms. Also, there are nuances involved in its anatomy that can be tricky to understand and critique.

We've covered compatible deck screws for all types of deck woods (e.g. natural wood, artificial wood, treated wood, etc.) in this guide.

However, choosing the best deck screws for pressure treated wood or lumber decks can be especially difficult, as buying factors increase in this situation. That’s why we’ve emphasized this issue and covered it in depth.

We hope this guide will be a "one-stop for all" solution for you when it comes to buying deck screws.
