Collar nuts are specialized fasteners characterized by their unique design, which includes a cylindrical shape with a collar or flange at one end. This distinctive feature allows for enhanced grip and stability when securing components together, making them particularly useful in applications where vibration or movement may otherwise loosen standard nuts. Typically made from durable materials such as steel or stainless steel, collar nuts are employed in various industries, including automotive, construction, and machinery, to ensure reliable connections. Their ability to provide a secure fit while also allowing for easy installation and removal makes them a preferred choice among engineers and technicians.
