Socket Head Shoulder Screws

Shoulder screws feature a socket head, a close tolerance body and a threaded portion smaller than the body. The area under the head may be undercut so that the head will seat on the work surface. The threads may be undercut so that a nut will go all the way to the end of the shoulder. Shoulder screws are often referred to as “Stripper Bolts”.
