Cap nut, also known as cap nut, is a hexagonal nut with a cap. Its main function is to prevent moisture or other corrosive substances from entering the inside of the nut, thereby playing a role in rust prevention and extending the service life of the nut and its connectors.
Structure and material
The cap nut consists of two parts: a stem and a cap. The stem is the main part of the nut, and its diameter is usually the same as the thread diameter of the nut, and its length is determined according to the needs; the cap is used to cover one end of the stem to protect the nut from external influences. The material of the cap nut can be carbon steel, alloy steel, stainless steel or non-ferrous metal.
Classification and use
Cap nuts can be classified according to use and material:
By use: ordinary cap nuts, anchor cap nuts, anti-theft cap nuts, etc.
By material: plastic, iron, copper, stainless steel, etc.
Cap nuts are widely used in various environments that require rust prevention and beauty, especially in the fields of automobiles, machines, building structures, etc., which can effectively prevent nuts from loosening, rusting or deformation. In addition, they can also be used on work equipment to secure tires and front and rear axles, as well as equipment that is frequently exposed to the sun and rain.

A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
