Shoulder Screws

A shoulder screw, also known as a shoulder bolt or stripper bolt, is a type of fastener that has a cylindrical shoulder section between the head and the threaded portion. The shoulder portion is larger in diameter than the threaded section, creating a smooth transition between the two sections.

These screws are designed to provide a precise and stable pivot or bearing surface in mechanical assemblies. The shoulder serves as a precise stop surface or bearing surface, allowing the screw to rotate while maintaining alignment and providing support for the components being fastened.

Shoulder screws are commonly used in applications where precise alignment, smooth movement, or load-bearing capabilities are required. They are often used in machinery, equipment, jigs, and fixtures where frequent assembly and disassembly are needed.

Shoulder screws come in various sizes, materials, and configurations to suit different applications and load requirements. They may have various head styles, such as socket head, slotted head, or hex head, depending on the specific application's needs.
