- Precise Class 6g thread fit ensures consistent engagement and reliable fastening in industrial assemblies
- High torque capability with 4mm hex socket drive providing secure installation without stripping
- Wide temperature tolerance (-50° to 250°F) allows performance stability across diverse operating conditions
- Superior mechanical strength with Rockwell B80 hardness for durable, long-lasting fastening solutions
- Regulatory compliance assurance meeting ASME B18.3.6M standards and RoHS 3/REACH environmental directives
Professional Applications & Engineering Value
This M8 set screw with nylon tip delivers critical engineering solutions for industrial applications requiring vibration resistance and surface protection. The 18-8 stainless steel construction provides exceptional corrosion resistance while the coarse thread (1.25mm pitch) ensures quick installation and reliable holding power. The headless design with 4mm hex drive allows for flush mounting in confined spaces, making it ideal for precision machinery, automotive components, and electronic enclosures where right-hand thread fasteners must maintain position under dynamic loads. The nylon 6/6 plastic tip prevents marring of contact surfaces while creating consistent clamping force, solving common loosening issues in rotating assemblies and adjustable mechanisms.
Specification Summary & Compliance
This metric set screw features M8 x 1.25mm coarse thread with Class 6g tolerance for precision fit, 20mm length, and Rockwell B80 hardness. Manufactured to ASME B18.3.6M specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both mechanical performance and regulatory adherence for global industrial applications.
