Shoulder Bolts

Shoulder bolts are used in machines where parts need to pivot slide or rotate around a fixed shaft. Their smooth shoulder acts as a guide or bearing surface for moving parts. These bolts are found in linkages molds gear assemblies and automation devices. They help maintain spacing between parts while allowing motion. Engineers use them for precise alignment and reduced wear. They are essential for systems requiring smooth and accurate movement.

Unlike regular bolts shoulder bolts have a long unthreaded section between the head and thread. This portion helps guide or support other parts that move or rotate around the bolt. Regular bolts are fully threaded and mainly used to clamp parts together. Shoulder bolts are more specialized and used where alignment or motion is required. They also offer a cleaner fit in assemblies that need tight spacing. The shape and function make them suitable for mechanical accuracy.

Yes shoulder bolts can be customized in shoulder length shoulder diameter thread size and head style. You can choose different materials based on load type or exposure to heat moisture or chemicals. Surface finishes can be added to prevent rust or friction wear. Orders can be produced to match machine blueprints or assembly layouts.
