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

Built for high‑strength fastening where additional length and load capacity are required, the 1/2"-13 × 2‑1/2" Grade 8 carriage bolt is well suited for demanding structural and industrial applications. The smooth, rounded head provides a clean, finished surface, while the square neck is designed to seat firmly into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener delivers exceptional tensile strength for load‑bearing and high‑stress assemblies. The plain, uncoated finish is ideal for controlled environments or applications where coatings are not needed. Commonly used in machinery frames, equipment mounts, fixtures, and structural connections requiring secure, extended‑reach fastening.
