How to use

Select the bit matching the screw head profile and insert it into the driver or bit holder until securely seated. For powered drivers, use appropriate speed and torque settings to avoid cam-out or damage to the screw head. When accessing screws in tight or deep locations, choose the longer 75 mm bit; use 30 mm bits for standard depth fastening. Return bits to their labeled positions in the case after use to preserve organization.

Usage recommendations

Use the correct bit profile and size for each fastener to minimize wear. Apply controlled torque and, where possible, pilot holes or lubrication on stubborn fasteners. Store the set in a dry place to prevent corrosion and keep the case closed during transport to avoid losing pieces.
