## Description

The Wera 840/1 ZBO Hex Pinned Security Bit Extra Tough is engineered for professional tradespeople who require robust, reliable bits for working with tamper-proof hexagon socket screws.

Designed specifically for hexagon socket BO screws with a protruding pin in their drive profile, these bits provide the security solution needed for applications where unauthorised loosening must be prevented. The tough viscous construction ensures durability when working with hard materials, whilst the 1/4" hexagon drive (Wera connecting series 1) offers universal compatibility with holders as per DIN ISO 1173-D 6.3. Available in sizes from 2mm to 6mm, all variants feature a consistent 25mm length.
