Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw delivers critical engineering value in demanding industrial settings where corrosion resistance and high tensile strength are paramount. Manufactured from 18-8 Stainless Steel, it effectively combats rust and chemical degradation in marine, construction, and chemical processing applications. The coarse UNC thread design prevents cross-threading and allows for rapid assembly in structural steel, machinery, and heavy equipment frameworks. With a fully threaded 8-inch length, it accommodates varying material thicknesses while maintaining consistent clamping force. The external hex drive and generous head dimensions enable high-torque installation with standard tools, reducing assembly time and labor costs in production and maintenance operations.
Specification Summary & Compliance
This hex head screw features precision UNC 5/8"-11 coarse threads with Class 2A thread fit for consistent dimensional accuracy and reliable performance. It is manufactured in compliance with ASME B18.2.1 specifications for hex bolts and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and regulatory adherence for global industrial use.
