05003031001 Zyklop 3/8" Hex socket bit with holding function Metric

When you are spinning wrenches on your Harley, the last thing you want is a rounded-off hex bolt. This Wera Zyklop 3/8 inch drive socket bit is a professional-grade solution for the workshop. It uses the Hex-Plus profile, which provides a much larger contact surface than standard bits to prevent fastener damage. This 4.0mm metric bit, model 8740 B HF, features a built-in holding function that keeps the bolt securely on the tool, which is ideal for reaching into those awkward gaps. At 35mm long, it is compact enough for tight clearances. The chrome vanadium construction has a durable brushed finish, and the base is knurled for easy finger-turning. It is color-coded for quick identification and fits standard 4mm hex socket bolts and screws. Note that this is for manual use only and not for impact guns.
