Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions where vibration resistance and secure fastening are paramount. The permanent nylon patch thread locker eliminates the need for secondary locking mechanisms, maintaining clamp force in high-vibration environments from automotive assemblies to industrial machinery. The UNC coarse thread configuration provides rapid installation while the cup point design creates permanent seating in shafts, collars, and pulleys. With Class 3A thread fit precision, this fastener ensures consistent performance in precision equipment, manufacturing fixtures, and power transmission systems where loosening could cause catastrophic failure. The combination of high-temperature resistance and Rockwell C45 hardness makes this set screw ideal for demanding industrial applications requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This 3/8"-16 UNC thread set screw features Class 3A thread fit for precision engagement and is manufactured to ASME B18.3 standards. The component is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial use. The coarse thread spacing and precise dimensional tolerances ensure compatibility with standard mating components across various industrial applications.
