- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure
- Exceptional mechanical strength delivering 75,000 PSI tensile strength and Rockwell B96 hardness for heavy-duty load-bearing applications
- Reliable thread engagement with Class 2A thread fit ensuring precise assembly and vibration resistance
- Optimized for high-torque applications featuring a 1 1/4" external hex head for secure tool gripping and easy installation
- Enhanced stability in assembled joints with 2" grip length and partial threading for controlled clamping force distribution
- Industry-standard compliance meeting ASTM A193 and ASTM Grade B8M specifications for guaranteed quality and performance
- Versatile coarse threading (3/4"-10 UNC) providing quick assembly and reduced cross-threading risk in industrial equipment
Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 3/4"-10 UNC hex head screw combines 316 Stainless Steel's corrosion resistance with ASTM Grade B8M certification to solve critical challenges in chemical processing, marine, and offshore applications. The partial threading design and 2" grip length prevent joint loosening under dynamic loads, while the coarse UNC thread ensures rapid installation in structural frameworks, heavy machinery, and pipeline systems. With 75,000 PSI tensile strength, it maintains integrity in high-stress connections, reducing maintenance frequency and downtime in corrosive or high-temperature settings where external hex drive accessibility is essential for serviceability.
Specification Summary & Compliance
This heavy-duty hex screw maintains precision Class 2A thread fit per UNC standards with 3/4"-10 coarse threading and 3 3/4" total length. Manufactured under ASTM A193 specifications with full ASTM Grade B8M compliance, it meets industrial mechanical and material requirements. The inch system measurements ensure compatibility with North American equipment, while 316 Stainless Steel composition supports RoHS and REACH environmental directives for restricted substance control.
