HiKOKI Cordless Nailers – First Fix vs. Second Fix Explained

HiKOKI Cordless Framing Nailer (First Fix)

The HiKOKI Cordless Framing Nailer is built for heavy-duty construction tasks such as framing, decking, fencing, and roofing. This tool drives large nails (typically up to 90 mm) with maximum holding strength, making it ideal for structural work where durability is key.

Because these nails are hidden by plaster, flooring, or cladding later in the build, the appearance of the nail holes isn’t a concern at this stage. The tool is larger, more powerful, and designed to work quickly and reliably on big jobs.

HiKOKI Cordless Finishing Nailer (Second Fix)

The HiKOKI Cordless Finishing Nailer is designed for detail-oriented, visible woodwork. It’s perfect for skirting boards, door frames, architraves, moldings, cabinetry, and other final fix work.

This compact, precise nailer uses smaller 15–16 gauge nails, leaving neat, discreet holes that are easy to fill or finish. It’s lighter, more ergonomic, and ensures a clean, professional result where the final look matters.

First Fix vs. Second Fix – What’s the Difference?

In construction, first fix refers to the structural stage: the unseen work such as stud walls, floors, ceilings, and roofing. Second fix happens later, after plastering, where the visible finishing touches are installed.

  • First Fix / Framing Nailers → Power and strength. Large nails for structural integrity.

  • Second Fix / Finishing Nailers → Precision and aesthetics. Smaller nails for visible trims and detail work.

Think of it this way: the framing nailer builds the skeleton, while the finishing nailer handles the polish.
