Heavy-duty hex nuts offer advantages over standard hex nuts

Heavy hex nuts are a type of nut that features a larger width across the flats compared to standard hex nuts. They are designed to provide a larger bearing surface and greater strength for applications that require high load-bearing capabilities.
Heavy hex nuts are manufactured from a wide range of materials, including carbon steel, stainless steel, alloy steel, and non-ferrous metals. The material choice depends on the specific application requirements, such as corrosion resistance, temperature resistance, or strength.

The larger size and increased width across the flats of heavy hex nuts contribute to their enhanced strength and load-bearing capability compared to standard hex nuts. They can handle higher axial loads and provide a more secure fastening solution in applications where significant forces are involved.
Heavy hex nuts are commonly used in heavy-duty industrial applications that involve high loads, such as construction, machinery, infrastructure, and automotive industries. They are frequently used in conjunction with heavy hex bolts or studs to provide a secure and reliable fastening solution.
Heavy hex nuts are manufactured to meet specific standards and specifications, such as ASTM A563, ASTM A194, ISO 4032, or DIN 934, among others. These standards define the dimensions, material requirements, and mechanical properties of heavy hex nuts.
