Professional Applications & Engineering Value
This M5 set screw delivers exceptional engineering value in applications requiring precise component positioning and reliable torque transmission. The alloy steel construction, hardened to Rockwell C45, provides superior resistance to vibrational loosening and mechanical stress in industrial machinery, automotive assemblies, and precision equipment. The headless hex drive design with 2.5mm drive size enables installation in confined spaces while maintaining high torque capability. The coarse thread pitch (0.8mm) ensures rapid installation without compromising holding power, while the cup tip creates positive engagement with shaft surfaces. These metric set screws solve critical alignment and retention challenges in manufacturing environments where space constraints and vibration resistance are primary concerns.
Specification Summary & Compliance
This precision set screw features M5x0.8mm coarse thread spacing with Class 5g6g thread fit tolerance according to ISO metric standards. The 4mm length provides compact fastening solutions while maintaining full thread engagement. Manufacturing complies with DIN 916 and ISO 4029 specifications, ensuring dimensional accuracy and performance consistency. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial components.
