Shoulder Screws

Common applications for Precision Shoulder Bolts include mounting gears, pulleys, and other rotating parts. Components can be mounted on Shoulder Screws and held in an axial position with springs. You can also create a cam follower by installing a bearing on the screw. When used in die sets, Shoulder Bolts are called “Stripper Bolts.”
A comprehensive explanation of the characteristics and shoulder bolt application can be found in our Shoulder Screw article.

Shoulder Screws, also referred to as Shoulder Bolts or Stripper Bolts, have undersize shoulder diameters and oversize shoulder lengths. The unique design allows for free rotational or axial motion of the component that is mounted on the screw.

Shoulder Screws surpass the quality and versatility of screws found in hardware stores, providing the ability to be used as a shaft, dowel, guide, axel, or pivot point. The hardened 416 stainless-steel construction and tight tolerances also offer a higher level of precision and meet compliance with ASME and other industry standards.
