wiha Werkstatt PH 1 screwdriver with a 107 mm blade manufactured to DIN ISO 8764 is designed for precise engagement with PH 1 cross-head screws. The tool features a hardened tip produced to the specified standard to ensure consistent fit and reduced cam‑out, while the ergonomic handle allows controlled torque application during assembly, repair and maintenance tasks. Its length and geometry make it suitable for work in confined spaces and for routine professional or DIY operations where repeatable screwdriving performance is required.

Advantages

The hardened tip matched to DIN ISO 8764 provides reliable torque transfer and minimizes slippage on PH 1 screws. The blade length of 107 mm offers reach into recessed or partially obstructed fasteners without compromising control.

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.
