When it comes to speeding up carpentry and joinery jobs, nothing beats the efficiency and power of a nail gun. But with so many options on the market, it's crucial to understand the difference between first fix and second fix nailers - especially if you're kitting out your tool bag for both structural and finishing work.
At United Fixings, we stock a wide range of first fix and second fix nail guns from trusted brands like Paslode, DeWalt, and Hikoki - and this guide will help you choose the right one for the job.
What Is a First Fix Nail Gun?
First fix nailers (also called framing nailers) are designed for heavy-duty structural work. These tools fire larger nails (typically 50–90mm) and are perfect for:
-
Stud wall framing
-
Roof battening
-
Floor joists
-
Decking
-
Fencing
They’re your go-to when strength and speed are more important than appearance.

🪚 What Is a Second Fix Nail Gun?

-
Skirting boards
-
Architraves
-
Door linings
-
Panelling
-
Cabinetry and trim
