The Wera 39679 TX SXL 9 Piece Multicolour HF Stainless 1 L-Key Set is a selection of long allen keys with holding function for improved hold. The stainless L-keys are hardened to the same strength as conventional carbon steel tools, and prevent extraneous rust forming. L-keys with a thermoplastic sleeve are manufactured out of easy-to-grip, circular material. The sleeve ensures that work is safe and comfortable even at low temperatures. Colour coding and large stamp to enable the desired L-key to be easily located. The HF tools developed by Wera are ideal because they feature an optimised geometry of the original TORX profile. The wedging forces resulting from the surface pressure between the drive tip and the screw profile mean that TORX screws made according to Acument Intellectual Properties specifications are securely held on the tool
