A Shoulder Bolt (also called Shoulder Screw or Stripper Bolt) is a precision-engineered fastener featuring a smooth, unthreaded shoulder between the head and threads. This design allows the bolt to function as a pivot, shaft, guide, or sliding mechanism in machinery.
Widely used in automation systems, tooling, molds, robotics, pulleys, and mechanical assemblies, shoulder bolts ensure accurate alignment, smooth movement, and high load stability.
