• Reliable coarse threading (UNC) for faster assembly and reduced cross-threading risks in industrial applications
• Full regulatory compliance including RoHS 3 and REACH for safe use across global markets
• Standardized dimensions per ASME B18.3 ensuring consistent performance and easy replacement

Professional Applications & Engineering Value

This 5-40 UNC set screw delivers critical engineering solutions where vibration resistance and positional security are paramount. The 18-8 stainless steel material provides excellent corrosion resistance, making it ideal for machinery, automotive assemblies, and outdoor equipment exposed to moisture. The headless hex drive and cup point tip work together to create deep, secure fastening without protruding components, perfect for precision applications requiring flush mounting. With Class 3A thread fit and coarse UNC threading, it maintains tight tolerances while allowing quick installation in high-volume production environments, significantly reducing assembly time and improving manufacturing efficiency.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit precision with UNC coarse threading (5-40 thread size) and complies with ASME B18.3 manufacturing specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial distribution worldwide.
