1/2"-13 × 5" Carriage Bolt – Grade 8, Plain Finish

Built for extra‑long fastening applications where strength and stability are critical, the 1/2"-13 × 5" Grade 8 carriage bolt is engineered to perform under heavy loads. The smooth, rounded head provides a clean exterior surface, while the square neck is designed to lock firmly into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener offers high tensile strength and durability for demanding structural and industrial use. The plain, uncoated finish is ideal for controlled environments or applications where coatings are unnecessary. Commonly used in machinery frames, heavy equipment mounts, structural supports, and industrial fixtures requiring extended reach and dependable clamping force.
