Key Features & Benefits at a Glance
- Permanent vibration resistance with nylon patch thread locker that maintains secure fastening in temperatures from -50° to 250°F
- Superior corrosion protection through black-oxide coating on alloy steel, extending service life in demanding industrial environments
- High-strength performance with Rockwell C45 hardness rating ensuring reliable load-bearing capacity and minimal deformation
- Precise installation control via 0.9mm hex drive design that prevents tool slippage and enables consistent torque application
- Optimized thread engagement with Class 5g6g thread fit and coarse pitch (0.4mm) for rapid assembly and reduced cross-threading risks
- Enhanced gripping power from cup point tip design that concentrates pressure for superior resistance to rotational loosening
- Global compliance assurance meeting DIN 916/ISO 4029 specifications along with RoHS 3 and REACH environmental regulations
Professional Applications & Engineering Value
This M2 set screw delivers critical vibration-resistant fastening for precision assemblies where space constraints demand headless design. The black-oxide alloy steel construction provides exceptional durability against environmental exposure, while the permanent nylon patch thread locker eliminates the need for secondary locking components in machinery, electronics, and automotive subassemblies. Engineered with Class 5g6g thread fit and coarse metric threading, it ensures rapid installation in high-volume production environments while maintaining secure positioning of gears, pulleys, and collars against shaft rotation. The cup point tip creates permanent seating marks for maximum resistance to loosening under dynamic loads.
Specification Summary & Compliance
Manufactured to DIN 916/ISO 4029 standards with Class 5g6g thread tolerance for precision fit. The metric coarse thread (M2 x 0.4mm) with right-hand direction ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety for global industrial applications.
