Hex nuts (also known as hexagon nuts) are the most commonly used standard threaded fasteners for industrial applications, conforming to DIN, ISO, GB, ASME, ANSI, etc. It is used in conjunction with bolts, screws, studs, anchors, and other fasteners with mechanical threads, to connect and fasten. It is available in strength ratings of 4, 6, 8, 10 and 12, depending on the material. Its hexagonal design facilitates the use of wrenches for installation and removal, and features strong fastening force and non-slip corners, making it suitable for a wide range of industrial, mechanical and structural connection scenarios.
