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

Manufactured for demanding applications where both strength and extended fastening length are critical, the 3/4"-10 × 4" Grade 8 carriage bolt delivers reliable performance under heavy loads. The smooth, domed head provides a clean finished surface and helps distribute clamping force evenly, while the square neck is designed to seat firmly into wood or metal to prevent rotation during installation. Produced from heat‑treated alloy steel, this Grade 8 fastener offers exceptional tensile strength and durability for structural and 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, heavy equipment mounts, structural supports, and industrial fixtures requiring secure, long‑reach fastening.
