At our factory, we are proud to manufacture high-quality DIN603 carriage bolts with a round head and square neck. These fasteners are designed with a smooth surface finish and precise dimensions to ensure reliable and consistent performance in a variety of applications. Made from durable and corrosion-resistant materials, our carriage bolts are perfect for use in construction, furniture assembly, and machinery. The unique square neck design prevents the bolt from turning when tightened, making them ideal for use with wooden structures and other materials that require a secure fastening solution. Trust in our expertise and experience to provide you with the best quality products that meet your needs.
