Installation Notes

Select the correct bit tip size and type before applying torque to avoid fastener damage or bit cam-out. Inspect bit tips for wear or chipping before use, as damaged bits can strip fasteners or slip unexpectedly. The quick-release mechanism should be fully engaged before driving to prevent the bit from ejecting under load.
