• Maximum holding power achieved through 90° cone point design that bites deeply into mating surfaces
• Enhanced durability with Rockwell B80 hardness, providing excellent wear resistance and longevity
• Easy installation and removal with hex drive design allowing high torque application without stripping
• Reliable performance ensured by compliance with ASME B18.3 manufacturing standards
• Environmental compliance meeting RoHS 3 and REACH regulations for safe usage across industries

Professional Applications & Engineering Value

This 3/8"-16 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent, vibration-resistant fastening. The 18-8 stainless steel construction provides excellent corrosion resistance in demanding environments, while the 90° cone point creates permanent seating by concentrating pressure on a small contact area. The Class 3A thread fit ensures precise engagement with mating components, preventing loosening under continuous vibration and thermal cycling. Particularly valuable in machinery assembly, power transmission systems, and precision equipment where headless design maintains clean profiles and the coarse UNC thread facilitates quick installation. The hex drive configuration allows for high torque application without cam-out, making it ideal for maintenance-critical applications requiring reliable, long-term positioning of gears, pulleys, and collars on shafts.
