Professional Applications & Engineering Value

This 3/8"-16 UNC shoulder screw delivers critical engineering solutions where precise component alignment and rotational movement are paramount. The steel construction with zinc plating provides durable corrosion protection in machinery, automotive, and industrial equipment applications. The 1/2" shoulder diameter with controlled tolerances ensures accurate positioning of moving parts, while the 1-7/8" shoulder length accommodates various assembly thicknesses. The external hex drive facilitates quick installation in confined spaces, and the Class 2A thread fit guarantees consistent performance in high-vibration environments. These features make it ideal for pivot points, gear assemblies, and precision mechanisms requiring reliable shoulder screw functionality with maintained concentricity.
