Professional Applications & Engineering Value
This brass set screw combines the inherent corrosion resistance of brass with precision Class 3A thread fit to solve critical fastening challenges in industrial settings. The UNC coarse thread configuration provides rapid assembly while maintaining exceptional holding power, particularly valuable in high-vibration environments where fastener loosening can compromise system integrity. The cup tip design bites securely into shaft materials without causing excessive deformation, making it ideal for positioning collars, gears, and pulleys on rotating equipment. The headless construction with hex drive allows for installation in confined spaces where traditional fasteners cannot be accommodated, while the Rockwell B55 hardness ensures the screw maintains its form under repeated adjustment cycles common in maintenance applications.
Specification Summary & Compliance
This 3/8"-16 UNC set screw features precision Class 3A thread fit with coarse thread spacing, manufactured to exacting dimensional standards. The fastener complies with ASME B18.3 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in various industrial applications without hazardous substance restrictions.
