05003033001 Zyklop 3/8" Hex socket bit with holding function Metric

This Wera Zyklop 3/8 inch drive socket bit is an essential for any mechanic working on metric-fastened components. Featuring the 8740 B HF designation, this 5.0mm bit includes Wera's Hex-Plus profile, which allows for higher torque transfer while protecting the bolt head from rounding. The integrated holding function is a standout feature, mechanically securing the bolt to the bit so it does not drop into the bike's internals during assembly. It is 35mm long, making it perfect for standard access jobs. The bit is forged from chrome vanadium with a brushed chrome finish and includes a knurled base for manual grip. It is color-coded for easy size selection and fits 5mm hex socket bolts and screws. This tool is designed for hand use and is not compatible with impact wrenches.
