3/4"-10 × 5" Carriage Bolt – Grade 8, Plain Finish

Engineered for extended fastening applications where maximum strength and reach are required, the 3/4"-10 × 5" Grade 8 carriage bolt is well suited for heavy structural and industrial use. The smooth, rounded head provides a clean exterior profile and helps distribute clamping force evenly across the surface, while the square neck is designed to pull tightly into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers high tensile strength and durability for demanding load‑bearing assemblies. The plain, uncoated finish makes it ideal for controlled environments or installations where surface coatings are unnecessary. Common applications include machinery frames, heavy equipment mounts, structural supports, and industrial fixtures requiring long‑reach, high‑strength fastening.
