How to use

Select the required tip orientation by reversing the tip mechanism according to the handle’s reversal method. Place the chosen tip into the screw head, apply steady axial pressure and rotate the handle in the correct direction to tighten or loosen the screw. Use controlled manual force to avoid cam‑out on Phillips heads and ensure the slotted tip sits squarely in flat screws. Keep the tool aligned with the fastener to maintain efficient torque transfer and minimize screw or tip damage.

Usage recommendations

Use the screwdriver for manual fastening only; avoid applying excessive force or using the tool with impact devices. For larger or heavily torqued fasteners, use an appropriately sized tool or powered driver. Store the screwdriver in a dry place and inspect the tip for wear before use to ensure reliable engagement with screw heads.
