• Regulatory compliance assurance meeting ASME B18.3 specifications and RoHS/REACH environmental standards

Professional Applications & Engineering Value

This 3/8"-16 UNC Class 3A hex headless set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor elements. The 90° cone point creates deep penetration into mating surfaces, preventing rotational movement in pulleys, gears, and collars. With its headless design and coarse UNC threads, this set screw offers reliable performance in high-stress assemblies while maintaining a low-profile installation. The Rockwell B80 hardness ensures the fastener maintains its structural integrity under continuous mechanical stress, making it particularly valuable for manufacturing equipment, automotive components, and heavy machinery where disassembly is infrequent but reliability is essential.
