Key Features & Benefits at a Glance
- Superior vibration resistance with cup point design that bites into surfaces for secure, long-term fastening
- Exceptional durability from Rockwell C45 hardened alloy steel that withstands heavy loads and repeated use
- Precise thread engagement with Class 5g6g tolerance ensuring consistent performance in demanding applications
- Easy installation and removal using standard 10mm hex tools without requiring additional clearance for screw heads
- Reliable coarse threading (2.5mm pitch) that resists loosening under dynamic loads and vibration
- Global compliance assurance meeting both DIN 916/ISO 4029 manufacturing standards and environmental regulations
- Optimized for industrial environments with right-hand threading compatible with standard assembly processes
Professional Applications & Engineering Value
This M20 set screw delivers critical engineering solutions where vibration resistance and positional security are paramount. The cup point design creates permanent seating by displacing material at the contact surface, preventing rotational slippage in high-torque applications. Manufactured from alloy steel with Rockwell C45 hardness, it maintains structural integrity under extreme mechanical stress while the headless configuration allows flush mounting in space-constrained assemblies. The metric coarse thread (2.5mm pitch) provides rapid installation and superior holding power in pulleys, gears, and collars where traditional fasteners might fail. These DIN 916/ISO 4029 compliant components are specifically engineered for heavy machinery, automotive systems, and industrial equipment requiring reliable set screw performance.
Specification Summary & Compliance
This metric set screw features M20x2.5mm coarse threading with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. The 50mm length with 10mm hex drive conforms to DIN 916 (ISO 4029) manufacturing specifications. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global industrial applications.
