Collection: Imperial Shoulder Screws

Shoulder screws, also called shoulder bolts, have a socket head, a precision plain shoulder and a shorter thread of smaller diameter. The shoulder acts as a pivot, axle or guide for levers, rollers and pulleys.

This imperial range has 3/8" and 5/8" shoulders with 5/16" BSW, 1/2" BSW and 1/2" UNC threads, in a bare finish. Order by shoulder diameter and shoulder length, then check the thread.

For metric sizes in grade 12.9, see Shoulder Screws.
