These custom partial thread socket shoulder bolts were manufactured for our automotive customer using 18-8 stainless steel material and cold formed 3/16 hex socket drive. Approximately .50" of 5/16-18 thread was incorporated and the shoulder measured .312" in diameter at 1.25" in length. The threaded section was turned down prior to thread roll operation.
