How to use

Select the PH 1 wiha Werkstatt screwdriver when the fastener head matches the PH 1 profile. Insert the tip fully into the screw recess, apply axial pressure to maintain engagement, and turn the handle with steady torque appropriate to the screw and material. For tight screws, apply controlled force to avoid stripping the screw head and use the handle to maintain alignment while turning. After use, store the screwdriver in a tool rack or holder to protect the hardened tip and maintain tip geometry.

Recommendations

Use the screwdriver only on correctly sized PH 1 cross‑head screws and avoid applying excessive torque beyond the screw or material limits. Inspect the tip for wear before use; a worn or damaged tip reduces engagement and increases the risk of cam‑out. For electrical work, ensure power is isolated and follow applicable safety procedures.
