Having a cap nailer in your toolset is something every DIY enthusiast should strive for, especially if you plan on doing a roofing project. Nailing by hand with a hammer-tacker might be faster, but it’s not as accurate or safe as a cap nailer.
Besides that, the cap nailer offers you stronger fastening and greater surface area protection with the cap. The cap fastener is way more durable and can easily withstand harsh weather or other calamities.
With a cap nailer in your hands, you can effortlessly do any roofing, siding, stapling, and more. In this review list and buying guide, we’ll be looking at the top cap nailers on the market.
Without further ado, let’s move on to the reviews for the best cap nailer in 2021.

1. DEWALT Brad Nailer Kit
The first contender for the best cap nailer is DeWalt‘s pneumatic model, the DWFP12231. It’s an excellent fastener and an overall great tool for a variety of tasks including cabinetry work. It has an operating pressure between 70 and 120 psi, and with it, you can effortlessly drive 18 gauge nails from 5/8″ to 2″ in length.
The DWFP12231 was built to last. Its maintenance-free motor keeps your working surface free of stains. On top of that, the rear exhaust keeps contamination away.
The biggest advantage of DeWalt‘s nailer lies in the tool’s oil-free operation. Because unlike most nailers of similar type, the DWFP12231 doesn’t require any lubrication—a brilliant feature that saves you a lot of time since you don’t have to lubricate the tool before every use.
Another superb feature is the tool-free jam release mechanism that allows you to easily remove nails.
Also, its 5.06 pounds weight means you can take it wherever you want. Its magnesium body is lightweight and sturdy.
Just like most of their tools, DeWalt designed the DWFP12231 brad nailer for user comfort. That can be seen from the integrated rubber grip feature and the adjustable belt hook that allows users to keep the nailer close to them.
- Proper setting of nail heads thanks to a tool-free depth-of-drive adjustment with detents
- Easily remove nails with the tool-free jam release mechanism
- Maintenance-free motor keeps the job site clean with oil-free feature
- Lightweight and ergonomic design for easy portability

2. Metabo HPT Finish Nailer Kit
Next in line is the pneumatic cap nailer NT65MA4 by Metabo HPT. For those unfamiliar with the recent changes, Metabo HPT is the new name of the world-renowned Japanese power tool manufacturer Hitachi.
This award-winning cap nailer by Metabo HPT is ideal for exterior trims, window and door casings, installing crown or base moldings, chair rails, cabinets, etc. It accepts 15-gauge nail fasteners from 1-1/4″ up to 2-1/2″ in length.
Hitachi’s NT65MA4 model weighs only 4.2 lbs, which increases maneuverability, reduces user fatigue, and makes it very easy to transport. It also comes with a selective actuation trigger that allows you to switch between sequential or contact (bump fire) nailing in a second.
Other great things about this nailer include the tool-free features for a faster nailing experience. The first is the tool-free nail extracting mechanism that allows for quick nail replacement or freeing a jammed nail. The second is the tool-free depth of drive adjustment for better control and professional finishing with flush fastening.
Then, we have the fully adjustable 360-degree exhaust portal. This helps keep exhaust air away from the operator.
However, one of the disadvantages of the NT65MA4 nailer compared to its DeWalt counterpart is the lack of the oil-free feature. You will have to frequently lubricate the nailer so it can ruin without issues.

Buying Guide for Cap Nailer
In most situations when buying the “best” tool, in this case – the best cap nailer, the deciding factor is the buyer himself. On the market, you’ll find dozens of excellent products, however, only a few will suit your needs.
That’s why it’s important to know what type of work you’ll be doing before buying a suitable cap nailer. Will you use it for framing, roofing, siding, flooring, trim work, moldings, or casings? Make sure you have the best cap nailer for the task.
What is a Cap Nailer?
A cap nailer is a type of nail gun that uses a cap fastener instead of the standard nail. The cap increases the surface zone which the nail protects, thus making it stronger. The cap also makes the fastener more durable during harsh weather conditions.
While the cap nailer is used for many applications, it’s most popular for roofing underlayment, felt, and house wrap.
What to Look for in a Cap Nailer?
On our list, every cap nailer is pneumatic (i.e. air-powered). Their operating pressure is 70-110/120 psi and all of them are well-balanced and durable with lightweight design. While we made sure all of them fall in the same range quality-wise, there are still differences between them.
Make sure you pay attention to the following:
- Weight – The lighter the tool, the easier it is to maneuver and shoot.
- Magazine Cap Capacity – Larger capacity makes for less reloading.
- Quick Load Magazine – Quickly reload your fasteners to save time.
- Contact/bump-fire vs Sequential fire mode – The first is faster but more dangerous, while the second is slower and safer.
- The Material – This tells you how durable, sturdy, and lightweight it is.
- Dry-fire lockout mechanism – Prevents the nailer from firing blanks
- Tool-free features – Whether for nail jam release, depth, or exhaust adjustment, tool-free is always faster.
- Oil-free operation – Saves you valuable time on lubrication.
When facing a roofing, siding, or similar project, your best investment would be a top-tier cap nailer. Hammer-tackers might give you the speed, but they can’t guarantee you accuracy, safety, or most importantly, surface protection like the cap nailer can.
To achieve that you’ll need a great nailer. That’s why in this guide we reviewed some of the best cap nailers on the market.
Depending on the type of job you’ll do, choose an adequate nailer for your needs.
