Shoulder Screws

Shoulder Screws, also referred to as Shoulder Bolts or Stripper Bolts, have undersized shoulder diameters and oversized shoulder lengths. The shoulder bolt’s unique design allows for the component's free rotational or axial motion when mounted on the screw.
A comprehensive explanation of characteristics and shoulder bolt applications can be found in our Shoulder Screw article
