Precision is necessary when it comes to construction projects. Getting the job done safely and adequately requires 100% accuracy. If you want to do the job well, you need the right tools.
Let’s discuss the differences between the two popular types of nailers to see which best suits your needs.
Why do nailers use angles?
Framing nails are always driven in on a 90-degree angle, so you might wonder why nailers come with different angles.
Packaging is the reason. The nails are angled onto paper strips and plastic, so the space on the strip is maximized. You don’t need as many stops to reload and more nails per section.

|Nail size||2 to 3 ½ -inches||2 to 3 ½ -inches|
|Flexibility||Less flexible||More flexible|
|Best usage||Siding, fencing, roof and wall sheathing, and framing||Woodworking, decking, hard lumber jobs, framing, and siding|
|Parts availability||Easier to find||Relatively hard to find|
|Usability||Can be used in tight places||Tough to use in smaller places|
A 21-degree framing nailer uses fewer nails than a large capacity nailer because it is mounted on plastic strips.
As each strip of nails contains only 60 to 70 nails, this type of nailer is best for small spaces like corners and bends.
This nail gun can hold 88 framing nails on two paper strips. You get twice the capacity of what you would with a 21-degree nailer.
Also, the packaging is made of paper strips, so it isn’t as messy as plastic ones.
Where to use
For siding, fencing, roof and wall sheathing, and framing, use a 21-degree framing nailer. 21-degree nail guns normally work with framing nails between 2″ and 3 1/2″.
When it comes to flexibility, you’ll want a 30-degree framing nailer. Most are suitable for woodworking, decking, hard lumber jobs, framing, and siding.
Step 1: Line up your framing nailer’s magazine with the guides on the plastic strip.
Step 2: Insert the nail strip slowly. The nails should not be forced into the gun. When the nails are kinked, there is a risk of the nail gun jamming or misfiring.
Step 1: Make sure there are no substances like oil on the paper.
Step 2: Feed the strips into the magazine slowly so you don’t tear the paper or create kinks.
How to use
Step 1: Place the nosepiece of the nailer at a 90-degree angle against the wall.
Step 2: Hole the gun securely with one finger sitting on the trigger and one hand under the gun.
Step 3: Put one hand on the top of the gun and slowly pull the trigger. Try not to pull away from what you are nailing into.
Step 1: Place the nose of your nailer onto the wood where you want the nail to go.
Step 2: Get a firm grip on the gun ad gently pull the trigger.

Which angle nailer should you use?
The 21-degree nailers work well for corners, but unfortunately, they are not as flexible as the other type. As a result, you can’t hold as many nails, and you must reload more frequently.
The good thing is their full-headed nails comply with building codes.
If you prefer a versatile nailer, this model has the largest capacity. Unfortunately, you need to keep it away from moisture as the paper strips will be destroyed.
Be careful as some offset or clipped head nails don’t always comply with.
