On this page18 sections
Mastering a modern finish nailer is the secret to completing immaculate interior trim installations quickly and efficiently on busy projects. Second fix nailers are designed specifically to provide reliable holding power in dry internal environments where precision is paramount. Typical applications include installing skirting boards, cabinetry, mouldings, door installations and other uses too.
These secondary tools utilise slender wire brads, pins, and nails with tiny heads that sink completely beneath the face of the wood. This fine profile leaves a minuscule entry point, allowing your final filler and paint trim to blend seamlessly. This comprehensive guide breaks down second fix nailer tool technology, fastener lengths, essential on-site applications for tradespeople and advice about buying the right nail gun.
What is a second fix nail gun?
A second fix nail gun is vital for any clean internal carpentry job. Second fix nail guns provide faster installation times compared to a manual hammer (or a traditional screw) and can drive up to 10,000 nails per charge. As opposed to a heavy first fix nail gun, a 2nd fix gun finishes highly visible internal woodwork neatly. The tool uses much thinner fasteners to secure delicate skirting boards and door frames cleanly. A smooth, precision nosepiece protects fine timber profiles from ugly surface bruises on-site.
Operators use a handy depth adjustment wheel to countersink brad nails perfectly every single time. A safety trigger allows for exact placement on detailed building furniture contracts. The compact straight nail magazine feeds fine wire pins flawlessly through the internal drive channel. If running a pneumatic setup, a standard air inlet connects the lightweight chassis to your hose. A second fix nail gun creates a vastly cleaner finish across all your delicate internal finishing work.
What are second fix nails?
In internal construction, choosing second fix nails over heavy roofing framing fasteners comes down to structural requirements. Second fix guns tend to use 16 or 18 gauge brad nails for finer work. They do lack the sheer holding power of larger nails, but they excel at securing lightweight interior trims.
Second fix nails cause less splitting in wood due to thinner nails. They accommodate nails, generally ranging from 16mm to 64mm in length. Second fix nailers leave very small holes that are easy to fill and paint over. The no-mar tips prevent marking painted or finished surfaces. They are referred to as finish pins because they handle final visible items like architraves and skirting boards perfectly.
Most site carpenters fire these slender nails with a pneumatic nailer connected to a portable site air compressor.

Alternatively, modern cordless gas tools provide excellent mobility when you need to carry your kit up high scaffolding towers. They ensure your final decorative mouldings stay secure without ruining the clean visual look of the modern house.

Step-by-step guide to using a second fix nail gun
Following the correct on-site procedure with your 2nd fix finishing tool guarantees clean results and total user safety:
- Set depth adjustment – adjust the driving power to suit your specific timber profile depth. This prevents your fine pins from over-penetrating the wood
- Position nose – depress the nose contact trip firmly against the trim surface. The tool will not fire until you complete this step
- Press contact trip firmly – ensure the metal pin sits flush with your timber casing. A clean entry point means less filling work for decorators
- Pull the trigger to fire – place the nose piece precisely where you need the fixing. This tool fires smaller nails compared to heavy framing gear
- Check the nail is flush – squeeze the trigger to activate the drive blade. Keep your hand steady to guide the fastener perfectly straight every time
