Wera 851/4 BTZ BiTorsion Extra Tough Phillips Screwdriver Bits PH3 50mm Pack of 1

This PH 3 x 50mm variant is designed for larger Phillips head screws commonly found in heavy-duty construction, structural applications, and industrial equipment assembly. The PH 3 size delivers maximum torque transfer for substantial fasteners, making it indispensable when working with larger fixtures and heavy-gauge materials. The 50mm length offers excellent accessibility for deeper recesses whilst the robust tip geometry ensures positive engagement with larger screw heads. The BiTorsion technology becomes particularly crucial at this size, as the increased torque demands place greater stress on the bit. The dual-zone construction effectively manages these peak loads, preventing premature failure and maintaining tip integrity even under sustained heavy use. Features and Benefits: • BiTorsion zone absorbs peak loads to protect bit integrity • Considerable reduction in breakage risk with significant service life increase • Ductile and tough construction for hard materials • ¼" hexagon
