Northwestern Socket Shoulder Screws: Precision Shoulder Bolt Solutions

Professional-Grade Socket Shoulder Screws from Your Trusted Michigan-Based Distributor

NW shoes are industrial “shoe”-style components used in fixtures and machine setups to provide a durable contact surface between a clamping element and the workpiece, or to act as a wear surface in sliding or repeated-contact applications (application dependent). In workholding and fixturing, shoes are commonly selected to help distribute load, improve stability, and protect parts from direct contact with harder clamp bodies. Because “shoe” styles vary widely, choosing the right part typically comes down to matching the geometry and mounting method to your clamp or fixture design.
