5/8"-11 × 3" Carriage Bolt – Grade 8, Plain Finish

Intended for heavy‑duty fastening where extended length and high load capacity are required, the 5/8"-11 × 3" Grade 8 carriage bolt provides exceptional strength and stability in demanding applications. The smooth, domed head offers a clean exterior finish and helps distribute clamping force evenly, while the square neck is designed to draw firmly into wood or metal to prevent rotation during installation. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers high tensile strength suitable for structural and load‑bearing assemblies. The plain, uncoated finish is ideal for controlled environments or applications where coatings are unnecessary. Common uses include machinery frames, equipment mounts, structural supports, and industrial fixtures requiring secure, long‑reach fastening.
