Professional Applications & Engineering Value
This M4 set screw with nylon patch locking addresses critical vibration-induced loosening in industrial machinery, automotive components, and precision equipment. The black-oxide alloy steel construction provides essential corrosion protection while maintaining Rockwell C45 hardness for repeated adjustment cycles without thread deformation. The hex drive configuration ensures positive torque application in confined spaces where headless design is mandatory. Engineered with coarse metric threads and Class 5g6g tolerance, this fastener delivers reliable performance in high-stress applications where vibration resistance and precise positioning are paramount for operational safety and reduced maintenance intervals.
Specification Summary & Compliance
This metric set screw features M4 x 0.7mm coarse threading with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. Manufactured to DIN 916/ISO 4029 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 8mm length with cup tip design provides consistent application performance across industrial assemblies requiring secure, vibration-resistant fastening solutions.
