Wera 840/1 Impaktor Hexagon Screwdriver Bits

This variant of the Wera 840/1 Impaktor Hexagon Screwdriver Bit is supplied in a 4mm hex size at 50mm length, available as a Pack of 5. The 50mm length makes this bit well suited to deeper or harder-to-reach fastening tasks where a standard short bit simply won't reach.

Wera's Impaktor technology ensures these bits can handle the high-impact forces generated by modern impact drivers, delivering an exceptional service life even under continuous heavy use. The diamond-particle coating on the tip bites firmly into the screw head, eliminating slippage, while the Hex-Plus profile increases contact area to reduce the risk of fastener damage.

Compatible with holders per DIN ISO 1173-F 6.3, these bits feature a 1/4" hexagon drive and include Wera's colour coding system for effortless identification on site.
