Cap nuts, also known as cap nuts, are a type of nut used for fastening and connection, and are widely used.
Prevent loosening and falling off:
Cap nuts are often used with stainless steel hexagonal slotted nuts, and cotter pins are used with screw bolts with holes. They are particularly suitable for situations where vibration and alternating loads are applied to prevent the nuts from loosening or falling off.
Cap nuts with inserts also play a role in preventing loosening by tightening the nuts to tap the internal threads, and have good elasticity.
Protecting threads:
Cap nuts can protect the threads of bolts or screws from the influence of the external environment, such as preventing moisture, dust and other impurities from entering the threaded connection, thereby extending the service life of the connection.
Easy to disassemble and assemble:
The design of the cap nut makes it difficult to slip when the nut is clamped with a wrench during assembly and disassembly. However, it should be noted that only adjustable wrenches, fixed wrenches, combination wrenches (opening part) or special square hole socket wrenches can be used for assembly and disassembly.
In some occasions, such as when frequent disassembly is required and the force is not large, cap nuts and ring nuts can usually be disassembled and assembled by hand without the use of tools.
Fixing and connection:
Cap nuts are mainly used on tires and front and rear axles of vehicles such as cars, tricycles, and electric vehicles to fix tires and maintain vehicle stability.
They are also commonly used to fix the base of street lamp stands that are often exposed to sunlight and rain, as well as some mechanical equipment.
Cap nuts are also suitable for many fields such as high-strength fasteners, mechanical fasteners, furniture fasteners, and vehicle fasteners.
Aesthetics and decoration:
The design of cap nuts can also make the connection parts neater and more beautiful, especially in some occasions with high requirements for appearance, such as furniture manufacturing, architectural decoration, etc.
In addition, the surface of cap nuts generally needs to be treated, such as zinc plating, nickel plating, chrome plating, and Dacromet surface treatment processes, to improve their rust resistance and service life. Among them, the chrome plating process is favored because of its smooth and bright surface and longer rust and corrosion resistance.
