The Forster Gunsmith Screwdriver #13 (brand part no. 001161) is a precision-ground single bit built to match firearm screw slots that a generic hardware driver will round off or cam out of. Forster Products machines the tip parallel and hollow-ground so it fills the slot’s full width instead of tapering, keeping torque on the screw instead of the slot walls. The #13 size sits in Forster’s numbered lineup for a specific factory slot width, making it a natural pickup for anyone rebuilding a driver set one size at a time. It belongs with the rest of our gunsmithing tools and gunsmith supplies for bench work where marred screws aren’t acceptable.

Key Specifications

• Parallel Tip, Hollow Ground The flat, parallel grind seats fully in the slot rather than riding up on the edges under torque.
• Numbered Size #13 Matches a specific factory screw-slot width in Forster’s sizing system for a snug, non-slipping fit.
• Sold Individually A single driver, useful for completing a set or swapping out a worn or mismatched tip.
• Gunsmith-Grade Steel Hardened tool steel meant for repeated use on firearm screws rather than general shop hardware.

Frequently Asked Questions

Why not just use a regular flathead driver? Standard tapered tips ride up in a gun screw’s parallel slot and cam out, rounding the slot edges and scratching finish around the head.

How do I know if #13 is the right size? Match it against the slot width on the screw you’re working with; Forster’s numbering runs across the common factory slot widths found on sights, grips, and action screws.
