How to use

Select the screwdriver with the correct tip size and type for the fastener to ensure secure engagement. Apply steady pressure while turning to maintain contact between the tip and the screw head; avoid excessive force that could damage the fastener or tip. For repeated high-torque work, use controlled, deliberate strokes and reposition the hand on the ergonomic handle as needed to maintain comfort and leverage. Store the set in a dry place to prevent corrosion and inspect tips regularly for wear.

Recommendations

Use the appropriate size screwdriver for each fastener to reduce wear and risk of slippage. Keep tips clean and free of debris, and replace tools if tips become rounded or damaged to maintain safe, accurate operation.
