Spline socket bit internal

This category contains individual sockets with an internal spline profile by Seneca. Spline is a multi-tooth profile found on certain bolts, including those used in cars. With the right spline socket you can loosen or tighten these bolts without damaging the profile.

All sockets have a 1/2 inch drive and are made of chrome vanadium steel. They are sold one by one in an extensive range of millimetre sizes, so you can choose exactly the socket you need or add to an existing set. They are intended for the garage and workshop. Protective impact sockets can be found in the same Sockets section.
