Professional Applications & Engineering Value
This M2.5 nylon patch locking set screw delivers critical vibration resistance in precision assemblies where loosening could cause equipment failure. The 18-8 stainless steel construction provides excellent corrosion resistance for automotive, electronics, and machinery applications exposed to moisture or chemicals. With its coarse thread pitch (0.45 mm) and Class 6g thread fit, installation is streamlined while maintaining secure fastening in right-hand thread configurations. The hex drive (1.3 mm) enables high-torque installation in confined spaces, while the headless design and cup tip create flush mounting with enhanced grip. These engineering features make it ideal for permanent assemblies in robotics, precision instruments, and industrial equipment where reliability is paramount.
Specification Summary & Compliance
This metric set screw features precise M2.5x0.45 mm coarse threading with Class 6g tolerance ensuring dimensional accuracy. Manufactured to DIN 916/ISO 4029 standards with Rockwell B80 hardness for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial fasteners.
