• Tip width: 3 mm
• Intended use: precision tasks, electronics and light mechanical work
• Handle type: slim/compact for fingertip control
• Overall size: compact design for access to confined spaces

How to use

Select the precision flat screwdriver when the slotted screw head matches the 3 mm tip width. Place the tip fully into the screw slot, apply steady axial pressure to maintain engagement, and turn the handle with controlled force to tighten or loosen the screw. Use small increments when working on delicate components to avoid applying excess torque. When accessing recessed screws, ensure the screwdriver is aligned with the screw axis to prevent tip damage or slippage.

Usage recommendations

For best results, use the screwdriver on screws that match the 3 mm flat tip and avoid forcing the tool on stripped or damaged heads. Keep the tip clean and visually inspect it for wear before precision tasks. Store in a protective toolbox or roll to prevent tip deformation and to maintain accurate performance.
