Product Description

The 3/8-16x5-3/4 bolts are high-strength threaded fasteners designed for industrial applications requiring secure mechanical connections. Featuring a 3/8-16 unified coarse thread pattern and a 5-3/4 inch shank length, these machine bolts are compatible with standard 3/8-16 threaded screws and nuts. Constructed from grade-5 carbon steel with zinc-plated or stainless steel finishes, they operate reliably across temperatures from -40°F to 250°F. Ideal for heavy machinery, automotive assemblies, and structural frameworks, these bolts deliver exceptional shear strength (up to 120 ksi) and corrosion resistance. While optimized for static load-bearing applications, their non-conductive coating limits electrical conductivity. The hexagonal head design enables easy installation using common wrenches, ensuring robust clamping force in high-vibration environments. Common industrial uses include equipment mounting, piping systems, and steel fabrication.
