855/4 BTH bits, PZ 3 x 50 mm

Torsion bits for Pozidriv* screws with elastic Torsion zone – where kinetic energy is diverted from peak loads – and softer BiTorsion zone to prevent the bit tip from twisting under peak loads. This greatly extends the product service life. This provides the best possible durability together with the matching holder. Extra-hard; ¼” hexagon, suitable for holders as per DIN ISO 1173-F 6.3. * Pozidriv = registered trademark of European Industrial Service Ltd.
