Description

These Wera 840/4 Z Hex Plus / Allen Key 50 mm Long Screwdriver Bits use a standard 1/4" hexagon drive (for 1/4" socket head screwdrivers) and are from their tough Z range of screwdriver bits.

They are made with Wera's Hex-Plus technology that's designed to greatly reduce the risk of stripping screws or nuts by operating with a larger contact surface (driving from the flats of the hexagon instead of the corners). We stock these in 4 mm and 5 mm sizes to cover the most common truss rod nut sizes on Asian made guitars (truss rods with socket/female style nuts). The size of driver is marked on the hex bits for quick and easy identification. We stock compatible bit holding screwdrivers like the Wera Kraftform Kompakt 812/1 Magnetic 1/4" Hexagon Bit Holding Screwdriver (Wera product code: 05051205001) and the Wera Kraftform Kompakt 817 R Bit Holding Screwdriver with Rapidaptor Quick Release Chuck (Wera product code: 05051482001) as separate items.
