Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw in 18-8 Stainless Steel addresses critical engineering needs in demanding applications. Its corrosion-resistant material prevents rust and degradation in outdoor, marine, or chemical-exposed settings, while the 80,000 psi tensile strength and Rockwell B70 hardness provide structural integrity for heavy machinery, construction, and infrastructure projects. The partially threaded configuration with coarse UNC threads offers optimal grip in soft materials and reduces the risk of cross-threading. With an external hex drive and 6 1/2" length, it simplifies installation in tight spaces, making it a reliable choice for industrial assembly, equipment manufacturing, and maintenance operations where durability and compliance are paramount.
Specification Summary & Compliance
This screw features a 5/8"-11 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy and easy assembly. It meets ASME B18.2.1 manufacturing standards, ensuring consistent quality and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for global industrial use.
