Shoulder Bolts

Shoulder bolts are used as bearings and spacers. Their applications number many: as shafts for cam rollers and other rotating parts, as pivots and stud bolts, and as bearing pins for swing arms, links and levers. Often combined with bronze sleeve (Oilite) bearings, they are also used as a guide in blanking and forming presses and in punch and die operations.Shoulder bolts have a cylindrical head, a smooth cylindrical shoulder and a short threaded section. A small area between the threads and shoulder is undercut, which allows for a tight fit against the mating surface. They are also known as stripper bolts, axle bolts, shoulder screws, hexagon socket head shoulder screws.
