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

Engineered for heavy‑duty fastening where both strength and added length are required, the 3/4"-10 × 3" Grade 8 carriage bolt is built for demanding structural and industrial applications. The smooth, rounded head provides a clean exterior appearance and even load distribution, while the square neck is designed to seat securely 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 machinery frames, equipment mounts, structural supports, and industrial fixtures requiring strong, mid‑length fastening.
