There are many things to take into account when buying a 21 Gauge Pin Nailer. Some of them are mentioned below:

User:

First of all, you must decide who will be using the tool. If you are buying the tool for yourself then you can go for a lightweight and stylish tool. 

However, if the tool is going to be used by many people in your office then you must opt for a heavy-duty tool. Such tools are built with high-quality material and hence last longer.

Environment:

Identify the place where you will be using the tool. This is important because it tells whether you need to go for a cordless Pin Nailer or a corded one. 

In case, you are going to use the tool indoors then you must opt for a corded 21 Gauge Pin Nailer. On the other hand, if you are going to use it outdoors then a cordless tool might be much suitable for you.

Size of the Nail Gun:

21 gauge pin nailers are available in different sizes. A roofing nailer or a framing nailer is under the classification of large body nailers as they can be used in basement framing work and roofing shingles.  

The brad nail gun or crown staplers are under the classification of small body nail guns. Due to their small build, they are used for smaller carpentry works. Keep these facts in mind when you look for a 21 gauge pin nailer.    

Ease of Use:

The best 21 gauge pin nailers are the simplest to operate. They should be easy to load with nails, hold steady while in use, and have a safety mechanism that automatically disengages when the trigger is pressed so there’s no risk of accidental discharge.

Safety Features:

Pin nailers are generally safe to use, but users should be wary of the threat of kickback, which is when the tool suddenly moves in a direction opposite to the one intended by the user because its fastener has become lodged in the workpiece.

To prevent this from happening, make sure that your pin nailer has some sort of safety device that prevents it from operating when the nose is pressed against a surface.

Furthermore, wearing protective goggles and thick gloves while working with this tool is highly recommended.

Price:

A 21 gauge pin nailer will cost anywhere from $200 or more. The price depends on brand name and features such as the number of nails it can fire at once, the type of trigger mechanism, and weight.

FAQ:

Can You Use a Pin Nailer for Crown Molding?
