Cap Nailer Buying Guide

Buying a cap nailer is an important decision. While at it, you need to realize that these machines don’t work the same. Factors such as nail size, nail/cap capacity, and more vary from model to model. Then again, the quality also differs.

If you’re shopping for the good quality cap nailer, here are some of the things to consider.

1. Compatible Caps and Nails

Compatible Caps and Nails

Cap nailers differ by the size and number of the caps and nails they can support.

Check the size of nails the nailer can support. You may see something like ¾ inches to 2 inches. Also, find out the size of caps the unit works with. In the description, you might find something like ‘works with 1-inch caps.’

After that, check the number of nails and caps you can load into the machine. Some can hold up to 100 nails while some can hold as many as 300. Remember, the higher the number, the fewer the times you will need to reload.

2. Size and Weight

The size and weight of the nail gun will determine the ease of maneuvering the device. As a DIYer, the last thing you need is something bulky and heavy. What you need is a machine that allows you to move easily and which doesn’t leave you fatigued after long durations of nailing.

Pay attention to the size of the nailer and watch the weight too. For ease of handling, the unit’s weight shouldn’t exceed 5 pounds.

3. Depth Adjustment 

While using a nailer, one of the crucial factors you have to mull over is the depth of drive. Depending on the material and thickness of what you’re nailing, you will want the nail to sink only to a certain extent. And to avoid either overdriving or underdriving the nail, you have to control the depth of drive.

If your nailer doesn’t come with the tool-free depth of drive adjustment feature, then you will need to keep changing the pressure of the compressor. That is not convenient, so it is advisable to get a gun with the depth adjustment feature.

4. Adjustable Exhaust

Imagine the exhaust blasting the gas in your face when nailing. It's not a good situation, is it? Thankfully, some models come with an adjustable exhaust. By rotating the exhaust to a different position, you're able to shift the gas and prevent it from blowing into your face.

While that is a feature you can pass on to save money, it is rather essential to have it.

3. Firing Mode

There are two basic firing modes – the bump/contact mode and the sequential firing mode.

The one you use should depend on your needs, especially experience and the time you have to complete the project.

Bump firing allows you to nail quickly but it is less safe. Therefore, it is suited for experienced users.

Sequential firing offers less speed but it is safer. For beginners, it is the right mode.

I’d advise you to go for a nailer that comes with interchangeable firing modes, so you can always use the mode that suits your needs.

People Also Asked:

1. What’s the Benefit of using Cap Nailer?

Ans: While a standard nailer drives the nail alone, a cap nailer drives the nail with a cap at the head. The cap increases the surface area of the head, thus securing the nail better. Moreover, the cap holds the material being nailed, thereby preventing it from tearing or cracking.

2. When Can I Use a Cap Nailer?

When Can I Use a Cap Nailer

Ans: Any time you want to secure a soft or dense material, a cap nailer might be the best option. It is often used to secure roof underlayment, house wraps, and felt. You can also use it to attach upholstery to furniture to give it a more secure hold.

3. Which One Between Standard Nails and Cap Nails is Better for Roofing?

Ans: When you nail the roof, you create holes that can give entry to rainwater. A nailing method that allows you to cover the holes as much as possible would be incredibly helpful, helping you avoid leaks and protect your roofing materials from water-damage.

That method is the cap nailing method. The caps create a better seal that keeps the water from entering a lot more reliably than a plain nail head.

4. Should I Hand-Nail My Roofing Shingles?

Ans: Hand nailing shingles is a time-consuming and rather exhausting process. If the wood is intact, it is a lot better to use a nailer for the speed, accuracy, and ease of use offered. You should only hand-nail when dealing with damaged wood.

Final Word

If you’re looking to install your roof fast and securely, the best cap nailer will come in handy. This machine is incredibly useful, allowing you to create water-tight connection points. When the rain or snow comes, the cap nail design will protect your roofing materials reliably, making them last longer. 

When looking for the right nailer, be sure to keep in mind the factors I talked about in the buying guide. Pay attention to the size of nails and caps supported and the nail and cap capacity.

Aside from that, factors such as depth adjustability, exhaust adjustability, and firing mode will determine the sort of experience you have when using your nailer.

It is my absolute conviction that with any of the models in the review, installing or replacing your roof will be a breeze.
