NUT

Wheel hub nuts are specialized nuts used to fix the outer wheels of vehicles.Like ordinary hexagonal nuts they also have various sizes between M12-M42. Compared with regular hexagonal nuts, wheel hub nuts are generally thicker than hexagonal standard nuts of the same specifications, and are generally fine threaded.The shape is the same as hexagonal nuts,however, there is a taper at one end of the nut.Some sedans pursue better appearance of wheel rims,the wheel hub nuts have a cover like a cap nut. Wheel nuts are usually used in conjunction with wheel hub bolts to ensure the safety and stability of the wheels. The wheel hub nut has good thread tightening performance and has undergone strict testing and inspection to ensure its tight fit with the wheel hub bolt, which is not easy to loosen or fall off. It can maintain a strong connection between the wheels and the vehicle axle, improving driving stability and safety.

Weld nut provided with lugs, annular rings, or embossments to facilitate its attachment to a metal part by resistance welding. They are fasteners with internal threads that are used in connecting with bolts, is designed to stand off the material to allow easy weld penetration, widely used automotive, machinery, pneumatic tools, furniture hardware, etc.

Welding nuts are a very important automotive connecting component with advantages such as fixation, safety, and reliability, which can be widely used in automotive manufacturing and maintenance. It plays an important role in improving the stability and durability of automotive structures.According to specific application scenarios and shapes, automotive welding nuts can be divided into various types such as, square nuts, T welding nuts, round welding nuts, etc..

A slotted nut is a hexagonal nut with opposing slots is cut into the top of the nut through the center of the plane. The groove is located at the end opposite the bearing surface. Slots for the insertion of a cotter pin to hold nuts when used with drill shank fasteners.

They are often used with shank or clevis bolts and are slotted to allow a cotter pin; they are generally used where shear strength is required. The function of slotted nuts in automotive industry is to fix the front and rear wheel axles of the vehicle by tightening the screws that pass through the front and rear wheel axles, so that the frame and tires are fixed together.

Flange nuts have a wide flange at one end that acts as an integrated, non-spinning washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. The flange is also serrated to provide a locking action. The serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations they cannot be used with a washer or on surfaces that must not be scratched. The serrations help in preventing the vibration of the nut from moving the fastener, thus maintaining the holding power of nut.There are a variety of serrated flange nut types in different grade and meet the standards of both DIN and ISO.

Rivet nuts, also known as pull rivet nuts or pull caps, are used in the fastening field of various metal sheets, pipes and other manufacturing industries. They are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decorations.Available in round, hex, and square body styles, our rivet nuts feature a variety of options and locking features. There are through-holes, blind holes, embossed and non embossed.

Developed to address the shortcomings of metal sheets and thin tubes, such as easy melting of nuts, easy welding deformation of substrates, and easy sliding of internal threads, it does not require internal threading, does not require welding of nuts, has high efficiency in riveting, and is convenient to use. Rivet nuts are mainly used in non structural load-bearing bolt connections, such as the connection of interior components such as rail cars, highway buses, and ships. The improved anti spin rivet nuts are superior to aircraft pallet nuts, with the advantage of lighter weight, no need to fix the pallet nuts with rivets in advance, and can be used with no operating space on the back of the substrate.

Nylon locking nut is a type of component in which a circle of elastic nylon is wrapped around a hexagonal nut, and the nylon is compressed during tightening, generating friction to prevent loosening. Its working principle is based on the friction force of the nylon ring. When an external force acts on the thread, the nylon ring is squeezed and embedded with the thread, forming an anti rotational torque, which can achieve the effect of anti loosening.

The basic structure of nylon lock nut consists of: nut shell, one end of the threaded hole nut shell is provided with a ring groove; the ring groove is provided with a nylon ring nut shell; the other end is provided with a riveted joint; riveting riveting riveting hole and connecting pieces of the. The utility model has the advantages of simple structure and convenient operation, and is especially suitable for occasions where the automobile and the aviation lamp are small and have high reliability requirements.
