Professional Applications & Engineering Value

This M8 x 1.25mm nylon tip set screw delivers exceptional engineering value in applications requiring vibration-resistant fastening. The 18-8 stainless steel construction provides corrosion resistance while maintaining Rockwell B80 hardness for structural integrity. The green nylon 6/6 plastic tip creates a secure, non-marring contact surface that prevents damage to precision components. The coarse thread pitch and Class 6g thread fit ensure quick installation and reliable holding power in machinery, automotive assemblies, and electronic enclosures. The headless hex socket design with 4mm drive is ideal for space-limited applications where flush mounting is critical, while the temperature-resistant nylon tip maintains performance across industrial operating conditions from -50° to 250°F.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threads with Class 6g tolerance for precision fit. Manufactured to ASME B18.3.6M specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The 18-8 stainless steel material and nylon 6/6 plastic tip meet industrial standards for mechanical performance and environmental safety requirements.
