Four different screw profiles (hexagonal socket screws sizes 2.5; 5.0; 6.0 and TORX® screws size TX 25) can be operated with just one bit. The enormous space savings make the bit perfect for mobile use. Significant weight savings of over 50 %. The operability of the large profiles is made possible by the spring compression of the small tips. The bit with a 1/4" hexagon drive (Wera connection series 1) can also be used with e.g. bit ratchets and bitholding screwdrivers with Rapidaptor.
