Professional Applications & Engineering Value

This 5/8"-11 UNC hex head screw is engineered to address critical sealing and high-pressure challenges in industrial settings. The 18-8 stainless steel material offers excellent corrosion resistance, while the silicone rubber O-ring provides a reliable seal against fluids and gases across a wide temperature range (-80° to 400°F). With a coarse UNC thread and Class 2A fit, it ensures quick assembly and vibration resistance in heavy machinery, pipeline systems, and pressure vessels. The external hex drive facilitates efficient installation, making it ideal for applications requiring high tensile strength (80,000 psi) and consistent performance under pressures up to 20,000 psi.

Specification Summary & Compliance

This screw features a 5/8"-11 UNC coarse thread with Class 2A dimensional accuracy for reliable fit. It is fully threaded and manufactured from 18-8 stainless steel with a Rockwell B85 hardness. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial fasteners.
