M12 Coach Bolts

M12 coach bolts, also known as M12 carriage bolts, are durable fasteners with a domed head and a square neck designed for secure fastening in wood or metal. The M12 size refers to the 12mm diameter of the threaded shaft, making these bolts ideal for heavy-duty applications such as construction, woodworking, and structural projects.

Their square neck prevents rotation during tightening, while the smooth, rounded head offers a clean, tamper-resistant finish. Suitable for both indoor and outdoor use, M12 coach bolts in stainless steel are often used in conjunction with nuts and washers for a firm, lasting hold.
