Socket Shoulder Screws
Similar Specifications: ANSI B18.3.3M, ISO 7379, DIN 9841.
Shoulder screws have an undercut portion between the thread and shoulder, allowing a close fit. They’re used for a wide range of punch and die operations, such as the location and retention of stripper plates, and act as a guide in blanking and forming presses.
Other applications for shoulder screws include: bearing pins for swing arms, links and levers, shafts for cam rolls and other rotating parts, pivots, and stud bolts. Shoulder screws are sometimes referred to as stripper bolts, resulting from their use with stripper plates and springs.
