Product Description

Product Description

    A cap nut is a special type of nut, which mainly consists of two parts: the nut body and the cap. The nut body is used to cooperate with bolts to achieve the fastening function, and its thread specifications and dimensions are similar to those of ordinary nuts, following the corresponding standard specifications. The cap part covers the top of the nut body, usually in the shape of a cylinder or a slightly tapered cylinder, and is closely connected to the nut body. Some are integrally formed, while others are connected by welding or other methods.

 

Materials of Cap Nut

 

Carbon Steel :Carbon steel cap nuts have relatively high strength and a relatively low price. These nuts can withstand relatively large tensile and compressive forces, and are suitable for general mechanical connections and building structure connections with high strength requirements.

Stainless Steel :They have good corrosion resistance and can be used in harsh environments such as humidity, acid, and alkali.

Copper :Copper cap nuts have good electrical conductivity and thermal conductivity, as well as a certain degree of corrosion resistance.

 

Product Parameters

 

Thread Specifications	The thread specifications of cap nuts are the same as those of ordinary nuts, including coarse threads and fine threads. Coarse thread specifications include M3, M4, M5, M6, M8, M10, M12, etc.
Cap Dimensions	The height of the cap varies with different specifications. Generally, for smaller-sized cap nuts such as M3 - M6, the cap height may be around 3 - 6 mm. For M8 - M12 cap nuts, the cap height can reach 6 - 10 mm. The outer diameter of the cap also has various sizes, usually slightly larger than the opposite side width of the nut body to ensure effective coverage of the threaded hole.

 

Product Advantages

Protection Function: Its main function is to protect the internal threads of the nut. By closing the threaded hole with the cap, it can prevent dust, moisture, corrosive liquids, and gases from entering the threads, reducing the corrosion and damage of the threads. 

Aesthetic Function: The appearance of cap nuts is more aesthetically pleasing than that of ordinary nuts. In some occasions with high appearance requirements, such as car interiors, precision instrument housings, high-end furniture, etc.

 

Application

 

Automobile Industry:In the engine compartment of a car, cap nuts can be used for some connection parts that do not directly contact high-temperature and highly corrosive liquids, which can prevent dust and moisture from entering and improve the overall aesthetics of the car. 
Mechanical Manufacturing:cap nuts can protect the threads from being affected by debris, coolant, and other impurities during the processing, and can also beautify the appearance of the equipment.
Furniture Industry:In the assembly of high-end furniture, cap nuts can hide the rough appearance of the nut body, making the furniture surface smoother, and can also prevent dust from entering the threads, which is suitable for connection parts such as drawer rails and cabinet hinges.
