Best Finish Nailer For Trim

The best finish nailer for trim will be a 15 or 16 gauge finish nail gun.

15 gauge finish nails will give you a slightly stronger fixing, but are also slightly thicker nails that leave bigger nail holes.

Thicker nails also means a greater chance of trim splitting if it’s thin across its width or depth, or if it’s a fine surface.

So, consider the size and profile of the nails, but also how heavy and thick the trim is when selecting a finish nailer (and what strength of fixing you need).

If the trim you’re installing is quite thin or delicate, consider either a brad nailer, or the thinner pin nailer for the job.

Back to the Hitachi, this finish nailer is a 15 gauge finish nailer, and some of the things that make it the best finish nailer for trim are:

  • It’s designed for installing internal trim like crown and base moldings, window and door casings, chair rails, cabinetry trim, exterior trim and staircases
  • It’s affordable – if you use it for one medium sized job, you will already get your value back for it compared to renting a nail gun
  • 34 degree Angle nail magazine – allows you to get into tight spaces and awkward angles around trim where a straight magazine might get in the way
  • Can shoot in two nail modes – sequential or contact nailing for either precision or fast paced nailing
