Shoulder Screws

Shoulder screws, also known as shoulder bolts or stripper bolts, are precision fasteners with a cylindrical, unthreaded shoulder between the head and the threaded portion. This design allows for precise spacing and alignment in mechanical assemblies. Typically made from stainless steel, aluminum, or brass, shoulder screws exhibit high corrosion resistance and durability. The smooth shoulder provides a bearing surface for rotating parts, reducing friction and wear. These screws are commonly used in industries such as electronics, automotive, and machinery, where precise positioning and secure fastening are crucial. Their versatility and reliability make shoulder screws essential components in various engineering applications.
