How to use

Select the spline bit that matches the fastener size to ensure proper engagement. Insert the bit into a compatible bit holder or screwdriver chuck and secure it before applying torque. Use steady, aligned pressure when driving or removing spline-head screws to avoid stripping the head. For power drivers, start at low speed and increase as the bit seats correctly in the fastener.

Usage recommendations

Inspect bits for wear before use and replace any damaged pieces to maintain secure fit and safe operation. Match bit size precisely to the spline fastener, and use appropriate torque settings when working with power tools to prevent fastener or bit damage.
