Professional Applications & Engineering Value
This 6-32 UNC thread set screw with nylon patch thread locker addresses critical vibration-induced loosening in industrial machinery, automotive components, and precision equipment. The black-oxide alloy steel construction combined with Rockwell C45 hardness ensures the fastener withstands repetitive stress while maintaining dimensional stability. The coarse UNC thread profile facilitates quick installation in production environments, while the cup tip design provides concentrated contact pressure for superior shaft positioning. Engineered for applications requiring high-temperature resistance and reliable locking without chemical adhesives, this headless set screw delivers consistent performance in assembly operations where space constraints and vibration are primary concerns.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for optimal engagement. Features 6-32 UNC coarse threads with right-hand direction and 3/8" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The nylon patch thread locker maintains effectiveness across the specified temperature range of -50°F to 250°F, meeting industrial requirements for chemical resistance and performance stability.
