3/4"-10 × 6" Carriage Bolt – Grade 8, Plain Finish

Designed for heavy‑duty fastening where maximum length and strength are required, the 3/4"-10 × 6" Grade 8 carriage bolt is built to perform in demanding structural and industrial applications. The smooth, domed head provides a finished appearance while distributing load evenly, and the square neck is engineered to lock into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers high tensile strength suitable for load‑bearing and high‑stress assemblies. The plain, uncoated finish is ideal for controlled environments or applications where surface coatings are unnecessary. Commonly used in structural frameworks, heavy equipment mounts, machinery bases, and industrial fixtures requiring long‑reach, high‑strength fastening.
