3/4"-10 × 4‑1/2" Carriage Bolt – Grade 8, Plain Finish

Designed for heavy‑duty fastening applications that require extended length and exceptional strength, the 3/4"-10 × 4‑1/2" Grade 8 carriage bolt is built to perform under high load conditions. The smooth, rounded head offers a clean, finished appearance and helps distribute clamping force evenly, while the square neck is engineered to seat securely into wood or metal to prevent rotation during installation. Manufactured from heat‑treated alloy steel, this Grade 8 fastener provides outstanding tensile strength and durability for structural and industrial use. The plain, uncoated finish is well suited for controlled environments or applications where surface coatings are not required. Common uses include machinery frames, heavy equipment mounts, structural supports, and industrial fixtures requiring long‑reach, high‑strength fastening.
