3/4"-10 × 2‑1/2" Carriage Bolt – Grade 8, Plain Finish

Built for heavy‑duty fastening where increased grip length and high strength are essential, the 3/4"-10 × 2‑1/2" Grade 8 carriage bolt delivers dependable performance in demanding structural and industrial applications. The smooth, domed head provides a clean exterior profile and helps distribute clamping force evenly, while the square neck is designed to lock into wood or metal to prevent rotation during tightening. Manufactured from heat‑treated alloy steel, this Grade 8 fastener offers exceptional tensile strength suitable for load‑bearing and high‑stress 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, structural supports, and industrial fixtures requiring strong, mid‑length fastening.
