• Excellent durability with Rockwell B96 hardness, providing long-term wear resistance and fastener integrity
• Precision thread fit with Class 2A UNC coarse threads for easier assembly and reduced galling risk
• Optimized drive engagement through external hex design and 1 1/16" head width for secure tool connection
• Versatile partial threading with 1 1/2" thread length allowing both secure fastening and adjustable grip
• Industry compliance assurance meeting ASTM A193 standards for guaranteed material quality and performance

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this 5/8"-11 UNC hex head screw combines 316 stainless steel corrosion resistance with ASTM Grade B8M mechanical properties to solve critical fastening challenges. The coarse thread design prevents cross-threading in field applications while maintaining Class 2A precision for consistent clamping force. Partially threaded configuration provides both secure engagement and unthreaded shank strength, making it ideal for structural connections, marine equipment, and chemical processing applications where vibration resistance and material integrity are paramount. The external hex drive ensures reliable torque transmission even in confined spaces.

Specification Summary & Compliance

This fastener maintains Class 2A thread fit per UNC standards with precise dimensional control. Manufacturing complies with ASTM A193 specifications for high-temperature service, while 316 stainless steel composition ensures compatibility with regulatory requirements including RoHS and REACH. The 75,000 psi tensile strength and Rockwell B96 hardness verify consistent performance across industrial applications.
