Import Carriage Bolts — Buy in wholesale FOB from Supplier in China

These carriage bolts feature a round head with a square neck, designed specifically for wood-to-wood or wood-to-metal connections where the square neck prevents rotation during tightening. The supplier stocks a full-thread range with diameters from 3/8 inch to 1-3/8 inch and lengths up to 17 inches, all produced to grade 10.9 for high-strength structural applications. No matching nuts are included, as these are typically paired with standard hex nuts or washers by the buyer.

Carriage bolts in this grade are manufactured from medium-carbon steel, quenched and tempered to achieve the mechanical properties required for grade 10.9 classification, which includes a minimum tensile strength of 900 MPa and yield strength of 720 MPa. The square neck under the head is machined to a standard 0.156 inch width for 3/8 inch to 1/2 inch diameters, scaling proportionally for larger sizes, ensuring a snug fit in pre-drilled wood holes. Surface finishes are typically plain or zinc-plated for corrosion resistance in indoor environments.

Common buyers include furniture manufacturers, timber frame constructors, and agricultural equipment producers who require reliable fasteners for heavy-duty wood joinery. These bolts are often used in outdoor applications such as decking, fencing, and playground equipment when paired with hot-dip galvanised or stainless steel variants. Importers should confirm bulk packaging options, as these are usually supplied in cartons or palletised boxes for export, with no minimum order quantity stated by the supplier.
