The KING TONY 4128PR is an 8-piece 1/2″ drive spline bit socket set covering sizes from 5mm to 16mm. Spline-profile fasteners require the correct matching driver to achieve proper engagement and reduce the risk of damaging the fastener. The 1/2″ drive format allows the bits to be used with compatible professional hand tools, making the set useful for specialised automotive, machinery, assembly and maintenance applications where spline fasteners are fitted.
