Hex Nut M14 M16 M18 Fastener Hardware Kit,a fastener hex nut is a type of hardware component that is used to secure a threaded fastener, such as a bolt or a screw. It is typically hexagonal in shape, with six flat sides and a threaded hole in the center. The hex nut is designed to be tightened onto the threaded fastener, creating a secure and stable connection between two objects.

The hex nut is often used in combination with a washer, which is placed between the nut and the surface of the object being secured. This helps to distribute the pressure evenly and prevent damage to the surface. Hex nuts are commonly made from steel, stainless steel, brass, or other materials, depending on the application and the level of corrosion resistance required.

The size of a hex nut is specified by the diameter and thread pitch of the fastener it is designed to fit onto. Common sizes include M4, M6, M8, M10, and M12, although larger and smaller sizes are also available. Hex nuts are widely used in construction, automotive, machinery, and other industries where secure fastening is critical.
