Speedmaster PCE408.1001 wheel studs feature a 1/2"-UNF thread, 3-inch overall length, and a 0.630" knurled shank diameter for a secure press-fit into the hub flange. Sold in a convenient set of five, these studs are engineered to provide reliable wheel retention and consistent torque loading at every installation.
The knurled shank locks firmly into the hub bore to resist rotation under load, making these studs a straightforward upgrade or direct replacement for worn or damaged factory studs. Always verify hub bore diameter and thread pitch against your specific application before installation.
