Professional Applications & Engineering Value
This M20 alloy steel set screw delivers critical engineering value in demanding applications where secure fastening and vibration resistance are paramount. The cup point tip bites deeply into shafts, gears, and collars, preventing rotational movement in machinery, automotive, and heavy equipment assemblies. Manufactured from high-strength alloy steel with Rockwell C45 hardness, it withstands dynamic loads and harsh operating conditions without loosening. The Class 5g6g thread fit and metric coarse threading ensure quick installation and reliable performance in high-stress environments, while the headless hex drive design allows for flush mounting in space-constrained applications. Compliant with DIN 916 and ISO 4029 standards, this screw provides consistent quality for OEM and MRO requirements across global industries.
Specification Summary & Compliance
This set screw features M20x2.5mm coarse threads with Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. The 35mm length and headless hex drive design comply with DIN 916/ISO 4029 manufacturing specifications. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and restricted substance control.
