Ribbed Neck Steel Zinc Plated Carriage Bolts 1/4-20X1/2 are heavy-duty fasteners designed for secure wood-to-wood assemblies. The ribbed neck improves grip during installation, while the zinc plating provides superior corrosion resistance for indoor and outdoor projects.

These carriage bolts feature a 1/4-20 UNC thread and measure 1/2 inch in length, making them ideal for furniture, decking, cabinetry, fencing, and other woodworking or light industrial applications. The domed carriage head and square neck under the head help prevent rotation while tightening.
