Alliance Fasteners can manufacture Shoulder Bolts to your requirements. Shoulder bolts, also known as Shoulder Screws and stripper bolts, are bolts that have a shoulder section between the threaded section and head, that is not threaded. This usually allows for the rotation of other parts such as gears or pulleys that might be attached with this bolt.
Alliance also has cold forging Thread Rolling capabilities. This helps to strengthen the threads, which in turn makes these bolts more suitable for higher strength applications.
