Wera 840/1 ZBO Hex Pinned Security Bit Extra Tough 3mm 25mm Pack of 1

This Wera 840/1 ZBO bit is supplied in a 3mm hex size with a 25mm length, a popular mid-range size well suited to hexagon socket BO security screws found across a wide variety of industrial and mechanical applications. From access panels to equipment housing, the 3mm drive covers a broad scope of tamper-proof fastening work. The Hex-Plus profile maximises the contact area between bit and screw head, cutting the risk of rounding and extending the working life of both the bit and the fastener. Extra tough materials ensure the bit can withstand the rigours of hard-material use without premature failure.
