Shoulder bolts, also called shoulder screws or stripper screws, are high-quality steel fasteners designed with an unthreaded cylindrical shoulder section between the head and the threaded portion. The unthreaded, large, and smooth shoulder allows the bolts to act as a pivot or shaft while securely fastening different components together. Shoulder screws offer high tolerances and can be used with other fasteners and washers for reliable movement requirements. Moreover, bespoke bolts can be easily tightened or removed using slotted drivers or hex keys. Apart from tightening applications, shoulder bolts serve as axles and pivot points, making them ideal for rotating or sliding components, including pulley shafts and bushes.
