Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 18-8 Stainless Steel hex head screw combines high tensile strength (80,000 PSI) and Rockwell B70 hardness to withstand mechanical stress and prevent stripping. The 5/8"-18 UNF fine thread enhances clamping force and resists loosening in vibrating machinery, making it ideal for heavy equipment, structural assemblies, and marine applications. Its fully threaded design ensures uniform load-bearing capacity, while the external hex drive facilitates quick installation in confined spaces. With excellent corrosion resistance, it reduces maintenance needs in chemical processing, outdoor infrastructure, and food-grade environments, delivering long-term reliability and cost savings.
Specification Summary & Compliance
This hex head screw adheres to UNF thread standards with a Class 2A thread fit for precise dimensional accuracy and interchangeability. Manufactured from 18-8 Stainless Steel, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The specifications include a thread size of 5/8"-18, length of 4 1/2", and full threading for consistent performance in industrial fastening applications.
