Stemco Spindle Nut

There are times when securing a wheel assembly involves more than just torque settings—proper component selection matters. The Stemco Spindle Nut uses a 3 1/4-inch thread and a retention system that locks the assembly into place without relying on cotter pins or traditional lock washers. This spindle nut format is widely used in axle maintenance where retaining torque settings across long mileage intervals is necessary. By streamlining hub service procedures and supporting consistent component retention, the Stemco 449-4973 serves both maintenance convenience and mechanical functionality.
