Nuts are a type of hardware component that typically feature a hexagonal piece with a threaded hole. Nuts are used in conjunction with bolts and other threaded fasteners to secure two or more components together. The threaded hole in a nut allows it to be tightened onto the threaded shaft of a bolt, creating a secure and stable joint.

Nuts come in various shapes and sizes, with the type of nut used depending on the specific application and the type of fastener being used.
