Professional Applications & Engineering Value
This alloy steel set screw delivers critical vibration resistance in high-stress industrial applications where loosening can cause equipment failure. The Nylon patch locking technology creates permanent friction against mating threads, eliminating the need for secondary locking mechanisms in machinery, automotive components, and power transmission systems. The extended tip design provides deeper seating in shaft collars and pulleys, while the UNC coarse thread facilitates quicker installation in production environments. With Class 3A thread fit precision and heat-resistant properties up to 250°F, this fastener maintains clamping force in applications subject to thermal cycling and dynamic loads, making it ideal for permanent assemblies requiring zero maintenance.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A external thread fit tolerance. Features UNC 3/8"-16 coarse threads with hex drive compatibility. The Nylon patch thread locker provides permanent locking function. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Material certification includes Rockwell C45 hardness rating for verified mechanical properties.
