⚡ At a Glance
- • Fit and Strength: Chrome Vanadium construction resists wear and handles high torque for M14 splines
- • Best for: Mechanics and DIYers working on Ford bell housings and recessed studs
- • Not ideal for: Jobs that require multiple bit sizes beyond M14 x 30 mm
Two M14 x 30 mm spline bits made from Chrome Vanadium tackle tight, high-torque studs. Specially shaped for Ford bell housings and intended for use with a 10 mm spanner.
Long-lasting performance - thanks to Chrome Vanadium construction
Chrome Vanadium is a heat-treated alloy known for tensile strength and resistance to wear under torque. The material keeps spline profiles from deforming during repeated use.
Durable finish means bits stay true when loosening stubborn studs, reducing the risk of rounding and the need for frequent replacement.
Access tight spaces - with a slim M14 x 30 mm spline length
The 30 mm length gives enough reach to clear bell housing lips while keeping a low profile for constrained areas. The M14 spline profile engages stud flats for positive drive.
Works in confined bell housing cavities where bulkier sockets cannot reach, so jobs proceed without dismantling surrounding components.
Designed for Ford bell housings - with compatibility for small spanners
Spline geometry and overall dimensions were developed to suit Ford bell housing fastenings, and the bit head accepts a 10 mm spanner for use where socket access is restricted.
Enables targeted repairs on Ford vehicles using only a small spanner, saving time and avoiding extra tool changes during maintenance.
