Professional Applications & Engineering Value

This 10-32 UNF shoulder screw delivers exceptional engineering value through its alloy steel construction and precision manufacturing. The combination of 140,000 psi tensile strength and Rockwell C32 hardness addresses common industrial challenges of component failure under heavy loads and wear. The black oxide finish provides reliable corrosion protection in demanding environments, while the Class 3A thread fit ensures consistent performance in precision assemblies. These shoulder screws are particularly valuable in applications requiring precise alignment, such as machinery guides, rotating assemblies, and precision instruments, where the 1/4" shoulder diameter serves as a reliable locating surface. The socket head design with hex drive facilitates easy installation in confined spaces, making them ideal for maintenance and production environments where accessibility is limited.
