How to use

Select the screwdriver when the blade width and tip profile match the fastener head to ensure full contact and reduce the risk of cam-out. Position the tip squarely in the screw slot, apply steady axial pressure, and turn using controlled wrist motion. For installation, maintain consistent torque and avoid over-tightening to prevent damage to the screw or workpiece. For removal, ensure the tip remains engaged to minimize slippage and rounding of the fastener head.

Recommendations

Inspect the tip periodically for wear and replace the tool if the tip is deformed or rounded. Use the screwdriver for compatible screw heads only; do not use as a pry bar, chisel, or for striking with a hammer. Store the tool in a dry place to avoid corrosion and keep the handle clean to preserve grip performance.
