- Superior corrosion protection through black-oxide coating on alloy steel, extending service life in demanding conditions
- Precise torque application enabled by 2.5mm hex drive design for reliable installation and removal
- Exceptional temperature tolerance with thread locker effective from -50° to 250° F for diverse industrial applications
- Optimized thread engagement through Class 5g6g tolerance and coarse thread spacing for quick assembly and reliable holding power
- Enhanced surface penetration with cup tip design that provides superior biting action on contact surfaces
- Consistent mechanical properties with Rockwell C45 hardness ensuring dimensional stability under load
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical vibration resistance in industrial machinery, automotive assemblies, and precision equipment where loosening under dynamic loads poses significant reliability concerns. The nylon patch thread locking technology creates consistent friction that prevents back-off without compromising reusability, while the cup tip design ensures maximum surface contact for superior clamping force. Manufactured to DIN 916/ISO 4029 standards with Class 5g6g thread fit, this metric set screw provides engineers with predictable performance in alignment-critical applications. The combination of Rockwell C45 hardness and temperature-stable locking makes it ideal for permanent fastening in motors, gearboxes, and rotating assemblies where thermal cycling and mechanical stress are constant challenges.
Specification Summary & Compliance
This M5 set screw features precise 0.8 mm pitch coarse threading with Class 5g6g tolerance according to ISO metric standards. The 20 mm length headless design with 2.5 mm hex drive conforms to DIN 916/ISO 4029 manufacturing specifications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
