• Secure and efficient installation using the standard hex socket drive, preventing cam-out and enabling high torque application.
• Wide compatibility with UNC coarse threads and Class 2A fit for easy assembly and interchangeability in standard industrial systems.
• Environmental compliance meeting RoHS 3 and REACH regulations, making it suitable for global supply chains and sensitive applications.
• Optimized thread engagement with a 3/16" thread length providing sufficient grip without unnecessary protrusion.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 18-8 stainless steel construction, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, automotive, and electronic enclosures operating in demanding conditions. The hex socket head allows for compact design and tool accessibility in confined spaces, while the precise shoulder acts as a pivot, spacer, or bearing surface, eliminating misalignment and reducing wear on moving parts. Its right-hand coarse threads ensure quick installation and high vibration resistance, delivering consistent performance in automated production lines and heavy-duty equipment.

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 tight tolerances: diameter of 7/32" (-0.001" to 0") and length of 3/16" (0" to 0.002"), ensuring precise fit in mating components. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for industrial and international markets without hazardous substances.
