Wera 867/4 HF Torx Screwdriver Bits T40 50mm Pack of 1

About this tool

This Wera 867/4 HF bit is supplied in T40 x 50mm, the largest size in this range, built to handle high-torque applications such as structural fixings, heavy-duty machinery assembly, and demanding industrial fastening tasks. At the T40 size, the HF (holding function) design proves especially effective — the optimised TORX® geometry generates a robust clamping force between bit and screw, keeping large, heavy fasteners under control on the bit tip and minimising the risk of cam-out under load. This bit is compatible with Würth ASSY and Altenloh SPAX T-STAR plus screws in addition to standard TORX® socket screws. The 1/4" hexagon drive conforms to DIN ISO 1173-F 6.3 for straightforward integration with standard bit holders and power tools, with colour-coding providing quick visual identification when working from a bit set.
