Professional Applications & Engineering Value
This M3 set screw delivers critical engineering solutions for applications requiring permanent, vibration-resistant fastening. The black-oxide alloy steel construction provides essential corrosion resistance while maintaining the Rockwell C45 hardness needed for high-stress environments. The permanent nylon patch thread locker eliminates the need for secondary locking mechanisms, solving common loosening issues in machinery, automotive assemblies, and precision equipment. With Class 5g6g thread fit and coarse thread spacing, installation is both precise and efficient, reducing assembly time while ensuring reliable performance in industrial set screw applications where maintenance access is limited.
Specification Summary & Compliance
This metric set screw features M3 x 0.5 mm coarse threads with Class 5g6g tolerance according to ISO metric standards. Manufacturing complies with DIN 916/ISO 4029 specifications for dimensional accuracy and performance. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for industrial components. The right-hand thread direction and 3 mm length provide standardized compatibility across metric fastener systems.
