How to use

Select the screwdriver when the slotted screw head matches the 5.5 mm blade width and 1.0 mm thickness. Insert the blade into the screw slot so the full working face contacts the screw head. Apply steady axial pressure and turn the handle to drive or remove the screw, keeping the blade aligned to avoid slipping. For electrical work, ensure power is isolated before use. After use, clean the blade and store the screwdriver in a dry tool rack to prevent corrosion and damage.

Usage recommendations

Use this screwdriver only on compatible slotted fasteners of matching size to avoid rounding the screw head. Do not use the screwdriver as a pry bar, chisel, or for striking; excessive side loads can damage the blade. Keep the blade tip clean and inspect for wear; replace the tool if the tip becomes rounded or deformed.
