How to use

Select the 4 mm hex bit required and insert it into your screwdriver, bit holder, or compatible power tool. Ensure the bit seats fully in the chuck or driver to avoid slippage. For impact applications, confirm the driver is rated for use with bits that have a torsion zone. After use, store bits in their holder or a suitable compartment to maintain the fluorescent coating and prevent loss.

Recommendations

For best results, use the Wiha 42105 bits with properly sized drivers and avoid excessive lateral loads. Use UV light in low-light environments to quickly locate fluorescent-marked bits. Replace bits once wear is visible on the tip to maintain secure screw engagement.
