The Forster Gunsmith Screwdriver #10 (brand part no. 001131) is a single-bit precision screwdriver built for the tight tolerances of firearm screw slots, where a standard hardware-store driver chews up bluing and rounds off slot edges. Forster Products ground this bit with a parallel, hollow-ground tip that fills the slot wall-to-wall rather than tapering to a point, so torque transfers evenly instead of camming the bit out under load. It’s sized as the #10 in Forster’s numbered lineup, matching a specific screw-slot width commonly found on sights, grip screws, and small action screws. Keep one in the bench set alongside the rest of our gunsmithing tools and gunsmith supplies for jobs where a marred screw head isn’t an option.

Key Specifications

• Parallel Tip, Hollow Ground The bit is ground flat and parallel rather than tapered, so it seats fully in the slot instead of riding up on the edges.
• Numbered Size #10 Forster’s numbering system matches specific factory slot widths, so picking the right number avoids a sloppy, damage-prone fit.
• Sold Individually This is a single bit, useful for filling out an existing driver set or replacing a worn tip.
• Gunsmith-Grade Steel Built from hardened tool steel intended for repeated use on firearm hardware rather than general shop work.

Frequently Asked Questions

What is a hollow-ground screwdriver tip? It’s a tip ground with parallel, slightly concave flats so it fills the full width and depth of a screw slot instead of tapering to a point, which is what prevents cam-out and slot damage.

Does this fit a standard bit holder? It’s built as a fixed driver rather than an interchangeable bit, matched to the #10 slot width in Forster’s sizing system.
