What Are Hex Nuts?

Hex nuts are six-sided internally threaded fasteners used with bolts, screws, and threaded rods to securely join two or more components. Their hexagonal shape allows easy tightening and removal using common hand tools while providing a strong and reliable connection.

Due to their versatility, hex nuts are among the most widely used fastening components across industrial, structural, and mechanical applications.
