Professional Applications & Engineering Value
These 18-8 stainless steel socket head cap screws with nylon patch locking technology solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and precision equipment. The UNC coarse thread design ensures rapid installation and reliable performance in high-cycle applications, while the Rockwell B70 hardness provides excellent wear resistance against repeated torque applications. The combination of fully threaded construction and Class 3A thread fit delivers superior load distribution and prevents joint failure in dynamic loading conditions. Engineered for industrial locking fasteners requiring consistent performance across temperature extremes from -70° to 250°F, these screws maintain their locking integrity where conventional fasteners would fail.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit for precision engagement and consistent performance. Features 1/4"-20 UNC coarse threads with right-hand direction and standard socket head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries and international markets.
