Every product page carries the standard it is built to, the catalogue group it belongs to, and the documents that go with it. Use the dimension table below to confirm sizes and tolerances, and the buttons to download the full PDF table or the CAD file for your drawing. If your application needs a size or a finish outside the table, our engineering team will review the drawing with you.

Heavy-duty hex nuts are used in structural applications, such as steel frameworks and bridges. They conform to specific strength and size...
