Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and stability challenges in precision assemblies. The 360 Brass construction offers inherent corrosion resistance and non-magnetic properties, making it ideal for electronics, instrumentation, and marine environments where signal interference or rust is a concern. The precise shoulder fit with tight diameter and length tolerances ensures accurate component positioning, reducing vibration-induced wear and misalignment in machinery, automotive, and aerospace applications. Combined with a socket head design and coarse thread, it allows for efficient installation in confined spaces, enhancing productivity in automated assembly lines while maintaining high tensile and shear strength for reliable performance under stress.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement and ease of assembly. The shoulder features precise dimensions: diameter of 5/32" (tolerance: -0.002" to 0") and length of 5/16" (tolerance: 0" to 0.003"), ensuring exact fit in precision bores. It is manufactured to meet RoHS 3 (2015/863/EU) compliance under exemption 6(c) for lead in copper alloys and is REACH (EC 1907/2006) compliant, confirming its suitability for regulated industrial and consumer applications.
