1/4"-20 × 3/4" Carriage Bolt – Grade 8, Plain Finish

Designed for high‑strength fastening in structural and industrial applications, the 1/4"-20 × 3/4" Grade 8 carriage bolt features a smooth, domed head with a square neck that prevents rotation during installation. Manufactured from hardened alloy steel, this fastener provides significantly higher tensile strength than standard carriage bolts, making it suitable for demanding load‑bearing applications. The plain (uncoated) finish is ideal for controlled environments or applications where plating is not required. Commonly used in machinery, equipment assemblies, frames, and structural connections where strength and secure fastening are critical.
