Spline socket bit external

Spline bolts have a multi-tooth profile and need a matching socket. This category contains Seneca spline sockets with 1/2 inch drive, which let you loosen and tighten these bolts with your ratchet or torque wrench.

The range is divided into two subcategories: Spline socket 1/2 inch 55mm and Spline socket 1/2 inch 100mm. The short sockets are handy in tight spaces, while the long sockets are for bolts that sit deeper. Both series are available in a range of M sizes, so you can choose the size that matches the bolt.

The spline sockets are intended for garages and workshops working on vehicles and machinery, and for topping up a socket set.
