05003080001 Zyklop 3/8" Hex socket bit w/ holding function US sizes

For the smaller imperial fasteners on your bike, this Wera Zyklop 3/8 inch drive socket bit is a professional-grade choice. This 1/8 inch US size bit features the 8740 B HF holding function, which mechanically locks the screw onto the bit so you do not lose hardware in the engine cases or frame. The Hex-Plus profile is engineered to prevent the rounding of socket heads by providing more surface contact. It is a compact 35mm long, perfect for standard access. Built from tough chrome vanadium with a brushed chrome finish, it also features a knurled base for better grip when turning by hand. It fits standard 1/8 inch hex socket bolts and screws. Like all precision Zyklop bits, this is intended for manual ratchets and should not be used with impact tools.
