Wera 851/1Z PH Extra Tough Phillips Screwdriver Bit – 8511ZPH

This Wera 851/1Z bit is sized PH3 with a 50mm length, combining the robustness of a PH3 tip with the extended reach of a 50mm shank. This makes it the ideal choice for driving large Phillips screws in deep countersinks, thick substrates, or when working with extension adaptors in structural and industrial settings. The extra tough construction is engineered to cope with the high torque forces typical of PH3 fasteners, maintaining tip integrity and reducing wear even in the hardest materials. Its 1/4" hexagonal shank conforms to DIN ISO 1173-D 6.3, ensuring a secure and stable fit in all compatible bit holders and power drivers. Features and Benefits: • PH3 tip delivers the engagement needed for large-headed Phillips fasteners • Extended 50mm length provides additional reach for deep fixings and adaptor use • Extra tough construction resists high-torque deformation and extends bit life • Reduced cam-out for improved control and fastener protection • 1/4" hex shank compatible with all DIN ISO 1173-D 6.3 compliant holding tools Contents: 851/1 Z bit, PH 3 x 50mm x 1 Specifications: Configuration: PH3 Size: 50mm
