A Hex Nut is a six-sided fastener with internal threads, designed to fit onto a bolt or screw with matching external threads. It is one of the most common types of nuts used for fastening and securing components together. The hexagonal shape allows it to be easily tightened or loosened using a wrench or spanner, providing a strong and reliable connection. ... Hex nuts are typically made from materials like carbon steel, stainless steel, or brass, offering durability and corrosion resistance. They are widely used in construction, machinery, automotive, and furniture applications, where secure fastening is required.
