Spline Bit Socket M10 140mm Long Reach 1/2in Drive

A long reach M10 spline bit socket with a 1/2in drive, used where extra access is needed around recessed or awkward fasteners. Built with an S2 steel bit, it is intended for cylinder head bolt work and other jobs where a standard length bit will not reach properly.

Used mainly for engine work, this socket suits vehicle maintenance, servicing and repair tasks where spline fasteners are fitted deep into the assembly. It is particularly relevant for cylinder head bolts on Ford, GM, Mercedes vans and VAG applications, making it useful for garage work, workshop use and more involved home mechanic jobs.

The 140mm overall length helps reach bolts positioned below covers, through narrow access points or past surrounding engine components. Its 1/2in drive fit makes it suitable for use with matching ratchets, breaker bars or other 1/2in drive tools already found in many tool kits. The M10 spline profile matches the stated fastener type, while the S2 steel bit is suited to repeated workshop use where strength and reliable engagement matter. For regular engine servicing, having the correct long reach socket close to hand helps avoid wasted time when access is tight.
