	      Socket shoulder screw with a UNC imperial coarse thread. They are also known as shoulder bolts, precision 
shoulder screw and in the US, stripper bolts. The main dimensions are for the diameter and total length 
required under the head. Shoulder screws have an undercut portion between the thread and shoulder, allowing 
a close fit. They are used in a wide range of punch and die operations and as shafts, pivots, guides, 
pins, linkages and trunnion mountings. Please note that the nominal diameter here refers to the shoulder 
diameter, except where shown otherwise.
