High-quality bits for TORX® screws. The TORX® HF (HF = Haltefunktion = holding function) tools developed by Wera are characterised by a geometric optimisation of the original TORX® profile. Due to the driving profile and screw profile pressing against each other, a clamping force is generated, and screws are securely held in the tool! Also suitable for Würth ASSY screws as well as Altenloh SPAX T-STAR plus screws.
