S-92198A828 5/8"-11 x 11" ASME B18.2.1 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• High tensile strength of 80,000 psi ensures reliable performance under heavy loads and stress
• Rockwell B70 hardness provides superior durability and resistance to wear and deformation
• Coarse UNC thread design allows for faster installation and reduced cross-threading risks
• Class 2A thread fit guarantees consistent, precise engagement with standard nuts and tapped holes
• Partially threaded shank offers optimal clamping force distribution for structural applications
• External hex drive enables easy installation with common tools, reducing assembly time

Professional Applications & Engineering Value

This 5/8"-11 UNC hex head screw delivers critical performance in demanding industrial settings where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents rust and chemical degradation in marine, chemical processing, and outdoor applications. With its coarse thread spacing and Class 2A thread fit, it maintains secure fastening in vibration-prone machinery while allowing for quick assembly. The partial threading design concentrates clamping force where needed most, making it ideal for structural steel connections, heavy equipment assembly, and infrastructure projects requiring 80,000 psi tensile strength and long-term reliability under dynamic loads.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerances for consistent performance. This 5/8"-11 UNC screw features a right-hand thread direction and coarse thread spacing in the inch system. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
