• High tensile strength of 75,000 psi ensures reliable performance under heavy loads and stress conditions
• ASTM Grade B8M certification guarantees consistent material quality and mechanical properties for critical applications
• External hex drive design provides secure tool engagement and easy installation with standard wrenching tools
• Class 2A thread fit offers optimal assembly clearance while maintaining vibration resistance in coarse UNC threading
• Partial threading configuration combines strong grip length with reduced thread galling risk in high-clamp force applications
• Rockwell B96 hardness rating delivers excellent wear resistance and durability through repeated use cycles

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 1/2"-13 UNC hex head screw addresses critical challenges in chemical processing, marine equipment, and offshore installations where corrosion resistance is paramount. The 316 stainless steel composition with ASTM A193 Grade B8M certification provides exceptional performance in chloride-rich environments that would rapidly degrade standard fasteners. The coarse UNC thread pattern ensures rapid assembly in structural connections and heavy machinery, while the partial threading design maximizes clamping force distribution across the 4 3/4" grip length. With 75,000 psi tensile strength and external hex drive compatibility, these screws deliver reliable fastening solutions for pressure vessels, pump systems, and structural frameworks requiring long-term durability in aggressive service conditions.

Specification Summary & Compliance

This hex head screw features precise 1/2"-13 UNC coarse threads with Class 2A thread fit tolerances, ensuring proper assembly clearance while maintaining vibration resistance. Manufactured to ASTM A193 specification for high-temperature service, the fastener meets ASTM Grade B8M requirements for chemical and mechanical properties. The inch system measurements include a 6" overall length with 1 1/4" thread length and 7/8" head width for standardized installation. Compliance with industry standards ensures consistent performance in industrial applications requiring reliable corrosion resistant fastening solutions.
