Shoulder Bolt-3/4 x 2-1/2
shoulder-bolt-3/4 x 2-1/2
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 a mating surface. Used as a bearing or spacer, their applications number many: as shafts for cam rolls and other rotating parts, as pivots and stud bolts, and as bearing pins for swing arms, links and levers. Shoulder bolts have a hex socket head so tighten using a hex driver.
