• Exceptional holding power with 90° cone point design that bites securely into mating surfaces
• Precise thread engagement with Class 5g6g tolerance ensuring reliable fastening performance
• High-strength durability from alloy steel construction with Rockwell C45 hardness rating
• Easy installation and removal using standard 3 mm hex drive tools
• Space-saving design with headless construction ideal for compact assemblies
• Regulatory compliance assurance meeting international standards and environmental regulations

Professional Applications & Engineering Value

This M6 set screw delivers exceptional engineering value in precision assembly applications where reliable positioning and secure fastening are critical. The zinc-plated alloy steel construction provides excellent corrosion protection while maintaining the Rockwell C45 hardness needed for repeated installations. The 90° cone point design creates positive locking action by concentrating pressure on a small contact area, preventing component slippage in high-vibration environments. As a headless set screw with metric coarse thread spacing, it offers flush mounting capabilities in machinery, automotive components, and precision equipment where protruding fasteners are impractical. The hex drive configuration ensures straightforward installation with standard tools, reducing assembly time while maintaining consistent torque values.
