Professional Applications & Engineering Value

This M8 set screw with nylon tip delivers critical engineering solutions for vibration-resistant applications across industrial machinery, automotive assemblies, and precision equipment. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining Rockwell B80 hardness for durable performance. The metric coarse thread (1.25mm pitch) enables quick installation and secure fastening in Class 6g tolerance applications. The headless design with 4mm hex drive allows for flush mounting in confined spaces, while the Nylon 6/6 plastic tip prevents damage to shaft surfaces and maintains grip under continuous vibration. This combination addresses common industrial challenges of component slippage, surface damage, and maintenance frequency in demanding environments.

Specification Summary & Compliance

Manufactured to ASME B18.3.6M specifications with Class 6g thread fit tolerance for precision metric threading. The screw features M8 x 1.25mm coarse threads, 10mm length, and 4mm hex socket drive. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across international markets. The nylon tip maintains dimensional stability across the specified temperature range of -50° to 250°F while providing consistent non-marring performance.
