Product Details
This hex head transmission sprocket nut from S&S Cycle is made from ASTM A563 steel, a solid material choice for this critical component. It features a 1-1/2-24 thread size with a left-hand thread direction, specifically designed for certain Big Twin (BT) transmissions from 1941 to 1992.
The left-hand thread is a key detail here; it means the nut tightens in the opposite direction of most fasteners, which is often used on transmission output shafts to prevent loosening under normal operation. This nut is built to the UNS-2B thread specification, ensuring a precise fit for the intended application. Its hex head design allows for a standard wrench or socket to be used during installation or removal.
