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

Designed for applications that require added fastening depth and high load capacity, the 1/2"-13 × 2‑1/4" Grade 8 carriage bolt provides dependable strength in demanding structural and industrial assemblies. The smooth, domed head offers a clean exterior appearance, while the square neck is engineered to pull securely into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers excellent tensile strength suitable for load‑bearing and high‑stress use. The plain, uncoated finish is ideal for controlled environments or installations where surface coatings are not required. Commonly used in machinery frames, equipment mounts, fixtures, and structural connections requiring secure, mid‑length high‑strength fastening.
