Professional Applications & Engineering Value

These 18-8 stainless steel hex head screws deliver exceptional performance in demanding industrial applications where corrosion resistance and mechanical strength are critical. The 1"-14 fine thread configuration provides superior vibration resistance compared to coarse threads, making them ideal for machinery, structural assemblies, and equipment subjected to dynamic loads. The partial threading design ensures optimal stress distribution along the shank, preventing thread stripping while maintaining clamping force. With external hex drive and substantial head dimensions, these fasteners enable efficient installation in confined spaces using standard tools. The combination of 80,000 psi tensile strength and Rockwell B70 hardness guarantees reliable performance in heavy-duty applications across manufacturing, construction, and marine industries.

Specification Summary & Compliance

This hex head screw features precise Class 2A thread fit with 1"-14 fine thread spacing in UNS thread type, ensuring dimensional accuracy and interchangeability. Manufacturing complies with ASME B18.2.1 specifications for consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) regulations for chemical safety. With a minimum thread length of 2 1/4" and overall length of 3", these fasteners provide reliable mechanical properties for industrial fastening applications requiring right-hand threading and partial threading configurations.
