14x1.5mm Racing Wheel Stud

This 14x1.5mm stud features a proprietary Teflon-Moly coating, significantly reducing thread friction. Its construction utilizes CNC thread-forming dies that create a more consistent and durable thread shape by re-aligning the steel's grain structure, a process superior to cut threads. Designed for large wheel fitments and compatible with wheel spacers up to 50mm, the R-Spec stud has become an industry standard. It features an extended shoulder to support the rotor hat and revised shoulder profiles for improved toughness. This stud fits any hub utilizing a .625” diameter knurl. For rear fitment or front applications with up to a 17mm spacer, a matching R-Spec Mid-Length Racing Wheel Stud is available. Key specifications for the standard R-Spec stud include a 14x1.5mm thread diameter and pitch, a 3.82” UHL to End of Thread, a 4.085” UHL to Bullet Tip, and a 2.90” Usable Thread Length. The knurl diameter and length are .625”x.275”. The product is made from proprietary, traceable steel, heat-treated to 185,000 psi for strength and durability. All MSI wheel studs are laser marked with a part number and manufacture date for traceability.
