Professional Applications & Engineering Value

This M3 set screw with nylon patch thread locker addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and precision equipment. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining mechanical integrity in demanding environments. The hex headless design allows for flush mounting in confined spaces, making it ideal for applications where protruding fasteners are impractical. The permanent thread locking mechanism activates immediately upon installation, eliminating the need for secondary locking compounds and reducing assembly time. With its coarse thread pitch and Class 6g thread fit, this metric fastener delivers reliable performance in high-vibration applications where maintaining precise component alignment is critical to operational safety and equipment longevity.

Specification Summary & Compliance

This precision-engineered set screw features M3 x 0.5 mm coarse metric thread with Class 6g thread fit tolerance, ensuring consistent engagement and reliable fastening performance. Manufactured to DIN 916/ISO 4029 specifications, the fastener maintains dimensional accuracy across all critical parameters. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components. The Rockwell B80 hardness specification ensures optimal mechanical properties for the application, while the right-hand thread direction follows international convention for ease of installation and compatibility with standard tooling.
