Professional Applications & Engineering Value
This alloy steel set screw with nylon patch locking technology addresses critical challenges in precision assemblies where vibration-induced loosening compromises equipment reliability. The Class 3A UNF fine threads provide exceptional dimensional accuracy for secure fastening in tight-tolerance applications, while the extended tip design enhances grip in soft materials or shallow holes. Engineered for industrial machinery, automotive components, and precision instruments, this headless hex drive screw combines high-temperature resistance with permanent locking performance, eliminating the need for secondary retention methods and reducing maintenance cycles in demanding operational environments.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A external thread fit and UNF fine thread profile (3/8"-24). The alloy steel construction achieves Rockwell C45 hardness for optimal strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Thread locker maintains integrity up to 250°F maximum temperature with precise tip dimensions (0.25" diameter, 0.099" length) ensuring consistent performance.
