How to use

Select a compatible square-drive holder or adapter that matches the DIN 3120 / ISO 1174 dimensions. Insert the screwdriver bit into the holder until the ball retaining groove engages to ensure a secure fit. Use the knurled grip for hand-operated turning; for power-assisted use, ensure the adapter and tool are rated for the intended torque. Position the PH tip in the screw recess and apply steady pressure while turning to avoid cam-out.

Recommendations

Inspect the bit before use for wear or damage to the tip. Clean and lightly lubricate the chrome-plated surfaces if exposed to moisture. Replace the bit if the tip shows rounding or deformation to maintain screw integrity and safety.
