Welcome to Handan Audiwell Metal Products Co., Ltd., a leading manufacturer and supplier of fastening solutions in China. We are proud to introduce our range of high-quality square head bolts and round head carriage bolts. Our square head bolts are designed to offer a stronger grip and are ideal for heavy-duty applications where high torque and tension forces are present. The square head design provides a large bearing surface which reduces the chance of the bolt becoming loose under load. On the other hand, our round head carriage bolts are widely used in woodworking and construction projects due to their smooth, low-profile head and the square neck which prevents the bolt from turning as it is tightened into the material. All our bolts are made from premium grade materials and are manufactured at our state-of-the-art factory using the latest technology and strict quality control processes. At Handan Audiwell Metal Products Co., Ltd., we are committed to providing the best products to our customers, and our square head bolts and round head carriage bolts are no exception.
