Wera 840/1 ZBO Hex Pinned Security Bit Extra Tough 2mm 25mm Pack of 1

This Wera 840/1 ZBO bit is supplied in a 2mm hex size with a 25mm length, making it the smallest option in the range and ideal for precision security fastening tasks involving compact hexagon socket BO screws. Whether working in electronics enclosures, machinery guards, or any application using small-format tamper-proof fixings, this bit delivers reliable performance where a standard hex tool simply won't work. Wera's Hex-Plus geometry ensures a larger contact area within the screw head, keeping wear and rounding to a minimum even under repeated use. The extra tough construction handles hard materials with confidence.
