05003089001 Zyklop 3/8" Hex socket bit w/ holding function US sizes

This Wera Zyklop 3/8" drive hex socket bit is a must-have for any mechanic working with 1/4" Allen head bolts. Part of the 8740 B HF series, it features Wera’s Hex-Plus profile, which provides a larger contact surface to prevent rounding out bolt heads—a common headache on older bikes. The built-in holding function keeps the fastener securely on the tool, making it much easier to start bolts in tight spots. It is constructed from chrome vanadium with a brushed chrome finish and includes a color-coded ring for quick identification. The base is knurled for manual turning, and it features a ball intercept ring for a secure fit. This 35mm long bit is designed for manual use and is not compatible with impact wrenches.
