05003840001 Zyklop 1/2" Hex socket bit with holding function

Reach deep-set metric hex bolts with this 140mm extended Wera Zyklop socket bit. This 4.0mm bit fits 1/2" drive ratchets and features the Hex-Plus profile, which increases the contact area inside the bolt head to prevent stripping. As part of the 8740 C HF series, it also includes a holding function that mechanically secures the fastener to the tool. The bit is made from chrome vanadium with a brushed chrome finish and is color-coded for quick selection. The base is knurled for easy manual rotation, and it includes a ball intercept ring for a secure connection to your ratchet. This tool is designed for manual use only and is not impact-rated.
