Product Description

The 3/8-16x2 Hex Bolt is a precision-engineered Grade 8 Heavy Duty Bolt designed for extreme load-bearing applications in industrial machinery, construction, and automotive assembly. With a 2-inch Zinc Plated Machine Screw configuration, it offers robust tensile strength (minimum 150 ksi) and corrosion resistance for harsh environments. The hex-head design ensures secure torque transmission up to 300 ft-lbs, compatible with standard 9/16" wrenches. Featuring a 3/8" nominal diameter and 16 threads per inch (UNF thread pattern), this fastener maintains structural integrity across temperatures from -65°F to 450°F. Its zinc plating provides durable protection against rust in outdoor or high-moisture settings. Typical industrial applications include heavy equipment manufacturing, steel frame connections, and high-vibration systems. Key advantages include superior shear strength and fatigue resistance, though the Grade 8 material requires proper hardening during installation to prevent brittleness. The 2" length allows secure fastening of materials up to 1.75" thick when paired with standard hex nuts.
