Professional Applications & Engineering Value

This M2.5 nylon patch locking set screw delivers critical vibration resistance for precision assemblies where loosening under dynamic loads poses significant reliability concerns. The 18-8 stainless steel construction provides essential corrosion resistance for industrial environments exposed to moisture, chemicals, or outdoor conditions, while the coarse pitch metric thread with Class 6g tolerance ensures rapid installation and secure fastening in production settings. The headless hex drive design allows flush mounting in applications where protruding fastener heads interfere with mechanical operation or aesthetic requirements. Particularly valuable in automotive components, electronic enclosures, and machinery assemblies, this set screw's nylon patch locking technology eliminates the need for secondary locking devices, streamlining assembly processes while maintaining secure fastening across the specified temperature range.

Specification Summary & Compliance

Manufactured to DIN 916/ISO 4029 standards with Class 6g thread fit precision for consistent mating with corresponding threaded components. The M2.5 x 0.45mm coarse pitch configuration provides optimal engagement characteristics, while the 3mm length delivers precise depth control. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications and export requirements.
