S-95362A620 3/4"-10 x 2" ASME B18.2.1, SAE J429, ASTM A354BD, MS90728-187 Mil. Spec. High-Strength Steel Hex Head Screws

Key Features & Benefits at a Glance

• Maximum load-bearing capacity with 150,000 PSI tensile strength for critical structural applications
• Superior corrosion resistance through zinc yellow-chromate plating in demanding environments
• Reliable thread engagement with Class 2A thread fit ensuring consistent installation performance
• Exceptional durability from Rockwell C33 hardness maintaining integrity under heavy stress
• Optimized drive efficiency with external hex design for high-torque applications
• Industry-standard compatibility through UNC coarse threading for easy replacement and maintenance
• Full regulatory compliance meeting REACH and multiple industrial specifications

Professional Applications & Engineering Value

This Grade 8 hex head screw delivers exceptional engineering value in heavy machinery, structural steel connections, and industrial equipment where failure is not an option. The 3/4"-10 UNC coarse thread configuration provides superior resistance to vibration loosening while enabling rapid installation in thick materials. The zinc yellow-chromate plating creates a protective barrier against corrosion in harsh industrial environments, significantly extending service life. With fully threaded construction and external hex drive, these fasteners maintain consistent clamping force across the entire 2" length, eliminating weak points in critical assemblies. The combination of 150,000 PSI tensile strength and Rockwell C33 hardness ensures these screws withstand extreme dynamic loads without deformation, making them ideal for construction equipment, transportation systems, and heavy-duty manufacturing applications where reliability is paramount.
