Product Description

The 5/8-11x1-1/4 Bolt is a precision-engineered 5/8-11 Hex Bolt designed for heavy-duty industrial applications, including construction, machinery assembly, and automotive systems. This 1-1/4 Inch Hex Bolt features a 5/8-inch diameter with 11 threads per inch and a 1.25-inch shank length, complying with ASTM A307 or SAE J429 standards for strength and durability. Manufactured from grade B7 or equivalent high-tensile steel with optional zinc-plated or hot-dip galvanized coating, it offers corrosion resistance in temperatures ranging from -50°F to 400°F (-45°C to 204°C). Its hexagonal head enables secure torque application up to 150 lb-ft (203 Nm) using standard wrenches. While excelling in load-bearing scenarios, installation requires proper alignment and thread lubrication to prevent galling. Typical applications include structural steel connections, equipment frames, and heavy machinery components requiring reliable shear and tensile strength.
