Professional Applications & Engineering Value
These nylon patch locking socket head cap screws provide critical vibration resistance in machinery, automotive, and aerospace assemblies where permanent thread locking is essential. The 18-8 stainless steel construction offers superior corrosion resistance for outdoor equipment and marine applications, while the Class 3A UNC coarse threads ensure rapid installation and reliable performance in high-volume manufacturing. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes these fasteners ideal for structural components subject to dynamic loads. The integrated nylon patch locking technology eliminates the need for separate locking washers or adhesives, streamlining assembly processes while maintaining secure fastening through thermal cycling and mechanical stress.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision dimensional accuracy. Features UNC coarse threads (2-56) with right-hand direction and fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 5/64" hex drive and standard socket head profile ensure compatibility with industry-standard installation tools.
