• Precision thread fit with Class 2A UNC coarse threads ensuring secure fastening and vibration resistance
• Optimized torque transmission through the external hex drive and 1 1/16" head width for easy installation with standard tools
• Enhanced durability with Rockwell B96 hardness and ASTM Grade B8M certification for long-term performance
• Versatile partial threading with 1 1/2" thread length allowing for both clamping and unthreaded shank benefits
• Industry compliance meeting ASTM A193 specifications for consistent quality and engineering reliability

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 316 Stainless Steel composition provides excellent protection against chloride-induced stress corrosion cracking, making it ideal for marine, chemical processing, and offshore applications. The partially threaded design combines the benefits of a secure threaded connection with an unthreaded shank that maintains alignment in structural assemblies. With its coarse UNC thread pattern and external hex drive, this fastener resists loosening under vibration while enabling high-torque installation in confined spaces. The 3 1/2" length and 2" grip length accommodate thick material sections commonly found in heavy machinery, construction equipment, and industrial infrastructure projects.

Specification Summary & Compliance

This inch system fastener features precision Class 2A thread fit with 5/8"-11 UNC coarse threads and right-hand thread direction. Manufacturing complies with ASTM A193 specifications for high-temperature service, while the ASTM Grade B8M certification ensures material consistency and performance reliability. The fastener meets industry standards for dimensional accuracy and mechanical properties, including 75,000 PSI tensile strength and Rockwell B96 hardness. The partially threaded configuration provides 1 1/2" of engaged threading with proper clearance fit for optimal load distribution in critical assemblies.
