1/2"-13 × 1‑1/4" Carriage Bolt – Grade 8, Plain Finish

Engineered for high‑load fastening where strength and stability are essential, the 1/2"-13 × 1‑1/4" Grade 8 carriage bolt is built for demanding structural and industrial applications. The smooth, domed head provides a clean finished appearance while distributing clamping force evenly, and the square neck is designed to lock into wood or metal to prevent rotation during installation. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers excellent tensile strength and durability for load‑bearing assemblies. The plain, uncoated finish is ideal for controlled environments or applications where surface coatings are not required. Commonly used in machinery frames, equipment mounts, fixtures, and structural connections requiring compact, high‑strength fastening.
