05003094001 Zyklop 3/8" Hex socket bit w/ holding function US sizes

For those hard-to-reach 3/8" Allen head bolts, this extended Wera Zyklop socket bit is the right tool for the job. Part of the 8740 B HF series, it features a 100mm overall length to provide the reach needed for deep-set fasteners. The Hex-Plus bit geometry offers a superior fit that prevents bolt head deformation, while the holding function keeps the screw securely attached to the tool. Constructed from chrome vanadium with a brushed chrome finish, it includes a color-coded identification ring and a knurled base for easy manual turning. This 3/8" drive bit is strictly for manual use and is not compatible with impact wrenches.
