Key Features & Benefits at a Glance
- Vibration-resistant locking with nylon patch thread locker, maintaining secure fastening from -50° to 250°F (-45° to 121°C) in demanding environments
- Superior durability and wear resistance from black-oxide alloy steel with Rockwell C45 hardness, extending service life in high-stress applications
- Precise Class 5g6g thread fit ensuring reliable engagement and consistent clamping force in metric assemblies
- Space-saving headless design with hex drive for flush mounting where protruding fasteners are impractical
- Enhanced grip and minimal surface damage from cup tip design, providing secure positioning without excessive marring
- Standardized metric coarse threading (M4 x 0.7mm) for quick installation and compatibility with common industrial components
- Regulatory compliance assurance meeting DIN 916/ISO 4029 specifications, RoHS 3, and REACH for global industrial use
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical reliability in precision assemblies where vibration loosening threatens operational integrity. The nylon patch thread locker creates consistent friction to resist rotational forces in machinery, automotive, and electronics applications, eliminating the need for secondary locking mechanisms. Engineered with M4 coarse threading and Class 5g6g tolerance, it ensures rapid installation while maintaining precise alignment in pulleys, gears, and collars. The headless hex design allows complete embedment in tight spaces, while the cup tip concentrates clamping force without damaging shaft surfaces. Combined with Rockwell C45 hardness, this fastener withstands repeated adjustments and high torque applications where softer fasteners would fail.
Specification Summary & Compliance
Manufactured to DIN 916/ISO 4029 standards with Class 5g6g thread fit for precision metric assemblies. The black-oxide alloy steel construction provides corrosion resistance and meets Rockwell C45 hardness specifications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions. Thread locker performance validated across -50° to 250°F operational range.
