Wheeler Fat Stix Limiter 30 in-lb Torque Screwdriver – Gunsmithing Tool

The Wheeler Fat Stix Limiter is a precision torque screwdriver designed for firearm maintenance and assembly, not a knife. This tool prevents over-torquing of scope rings, bases, action screws, and other critical fasteners by limiting output to 30 inch-pounds—a common spec for many optics mounts and receiver screws. The preset limiter clicks when proper torque is reached, protecting threads and preventing damage to firearms or accessories.

The ergonomic handle provides comfortable grip during repetitive work, while the magnetic bit holder accepts standard 1/4-inch hex bits (bits not included). Compact enough for range bags or field kits, the Fat Stix delivers consistent, repeatable torque values essential for maintaining zero and ensuring reliable performance. Ideal for shooters who mount their own optics or perform routine maintenance.
