Square nuts are commonly used in channels, slots, or welded to components. Their large flat surface area provides greater resistance to loosening and offers a strong grip in tight alignment environments.
Coupling nuts, also known as extension nuts, are designed to connect two male threads or threaded rods together. They are essential for extending length in structural and plumbing setups.
Flange nuts feature a wide flange at one end that acts as an integrated washer. This helps to distribute the pressure of the nut over the secured part, reducing damage and compensating for uneven mounting surfaces.
Lock nuts employ specialized friction-generating mechanisms—such as nylon inserts or distorted threads—to resist vibration and rotational force, preventing the fastener from backing off.
Crown cap nuts, or dome nuts, cover the exposed end of a bolt. They provide a clean, finished aesthetic and prevent injuries caused by contact with sharp thread ends.
Cage nuts combine a spring steel cage with a square nut. They allow for slight adjustments in mounting and thread alignment, making them the standard choice for server racks and electrical cabinets.
