Wheeler 100-Piece Professional FAT Wrench Screwdriver Set

The Wheeler 100-Piece Professional F.A.T. Wrench Screwdriver Set (brand part no. 4001004) combines Wheeler’s iconic F.A.T. Wrench with 98 additional screwdriver bits and adapters, built into a gunsmith’s dream kit for fastening jobs across a whole shop rather than a single build. Wheeler’s F.A.T. Wrench delivers a 10-65 in-lb torque range for perfect, repeatable consistency, while both the wrench and the included 1/4-inch driver handle feature a texturized rubber grip for a comfortable, secure hold. Hollow-ground flat bits create a precise fit that prevents damage to screws and firearm finishes alike. A molded case keeps every bit and driver organized so nothing goes missing between jobs, and the bits carry a black phosphate coating to resist rust over years of shop use.
