How to use

Select the Wiha 42420 Single Standard screwdriver when the screw head matches the standard slotted tip. Position the tip squarely in the screw slot to ensure full contact, apply steady axial pressure, and turn the handle in the required direction to tighten or loosen the fastener. Use controlled force to avoid damaging the screw head; for high-torque applications consider appropriate power tools or larger manual drivers. Maintain a firm grip on the ergonomic handle to ensure precise control during insertion, adjustment, or removal of screws.

Recommendations

Inspect the screwdriver tip regularly for wear or deformation and replace the tool if the tip no longer fits securely in screw slots. Keep the blade clean and free of grease to maintain good contact, and store the screwdriver in a dry place to prevent corrosion.
