Professional Applications & Engineering Value
These 18-8 stainless steel hex head screws with nylon patch locking technology deliver critical vibration resistance in demanding industrial applications. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures structural integrity in machinery, equipment assembly, and automotive components where dynamic loads are present. The UNC coarse thread pattern with Class 2A tolerance provides reliable engagement in various materials, while the permanent nylon patch locking mechanism eliminates the need for secondary locking devices, streamlining assembly processes. Engineered for environments requiring temperature stability from -55° to 250°F, these fasteners maintain consistent performance in outdoor, manufacturing, and transportation applications where thermal cycling occurs.
Specification Summary & Compliance
Manufactured to precise dimensional standards with UNC 1/4"-20 thread size and Class 2A thread fit for consistent installation performance. The external hex drive (7/16" width, 5/32" height) accommodates standard tooling. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance. Right-hand thread direction with coarse spacing provides optimal engagement in most industrial materials.
