Key Features & Benefits at a Glance
- Superior holding power with Class 6g thread fit ensuring precise engagement and vibration resistance in demanding assemblies
- Enhanced durability from alloy steel construction with Rockwell C39 hardness for long-term performance under stress
- Secure installation using a standard 1.5mm hex drive that prevents tool slippage and ensures consistent torque application
- Reduced component damage thanks to the ball tip design that distributes pressure evenly on contact surfaces
- Reliable coarse threading (0.5mm pitch) enabling faster installation and better performance in softer materials
- Regulatory compliance with RoHS 3 standards, making it suitable for environmentally conscious industrial applications
- Space-saving headless design allowing flush mounting where protruding fastener heads are not feasible
Professional Applications & Engineering Value
This M3 set screw delivers critical engineering solutions for precision assemblies requiring secure component positioning. The alloy steel construction and Rockwell C39 hardness provide exceptional resistance to loosening under vibration and thermal cycling, making it ideal for motor mounts, gear assemblies, and precision machinery. The ball tip design minimizes marring on shafts and components while maintaining positive engagement. With its metric coarse thread (0.5mm pitch) and Class 6g thread fit, this hex headless set screw ensures rapid installation in automated production environments while maintaining precise alignment in industrial applications where space constraints demand compact fastening solutions.
Specification Summary & Compliance
This precision fastener features M3 x 0.5mm coarse metric thread with Class 6g thread fit tolerance, 5mm length, and 1.5mm hex drive. Manufactured from alloy steel with Rockwell C39 hardness and ball tip configuration. Compliant with RoHS 3 (2015/863/EU) regulations under exemption 6(a) for lead as an alloying element in steel, ensuring environmental responsibility while maintaining mechanical performance standards.
