Socket Shoulder Bolts are also known as Stripper Bolts after their original use in the stripper plate of a die set for stamping presses. Now used in many more applications, including precision electronics, construction, machinery, exercise equipment, automotive, and general industrial and manufacturing. The Shoulder Bolt has a Socket Head that is nicely finished (with or without knurling on the outside of the head) and the hex broach provides fast and secure tightening. The shoulder has a close tolerance to the minus side, so it fits correctly into precision machined holes. Threads are manufactured to a class 3A fit, which is a tigher tolerance than the standard fastener class 2A thread specification.
