Professional Applications & Engineering Value
This M2.5 set screw delivers critical engineering solutions for industrial applications requiring secure, permanent fastening. The black-oxide alloy steel construction combined with Rockwell C45 hardness ensures exceptional strength and wear resistance in high-stress assemblies. The nylon patch thread locker effectively counters vibration-induced loosening, making it ideal for machinery, automotive components, and precision equipment where maintenance access is limited. The headless design with hex drive enables flush installation while maintaining tool accessibility. With Class 5g6g thread fit and coarse 0.45mm pitch, this metric set screw provides reliable engagement and simplified installation in production environments.
Specification Summary & Compliance
This precision set screw features M2.5 thread size with 0.45mm coarse pitch and 5mm length, manufactured to Class 5g6g thread tolerance for consistent fit and performance. Compliant with DIN 916 and ISO 4029 standards, ensuring dimensional accuracy and manufacturing consistency. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and regulatory adherence in industrial applications.
