Tork Craft Socket Bit 1/2′ Drive Spline M8 S2 Material

At a Glance: 1/2′ drive spline M8 socket bit in S2 steel for secure engagement and high-torque fastening.

The Tork Craft TC97008 spline socket bit is designed for driving M8 spline (triple square style) fasteners using a 1/2′ drive ratchet, breaker bar or torque tool—ideal for higher-torque applications where strong engagement is essential. Spline fasteners are popular in automotive and mechanical assemblies because the multi-point profile delivers excellent torque transfer when fully seated, helping reduce the risk of slipping. Made from durable S2 steel for strength and wear resistance, this socket bit is built to keep a crisp profile under load, making it easier to tighten correctly and to remove stubborn fasteners without damaging the head.
