What types of nuts are there?

The nut is an integral part of the machinery. It is usually used to fix mechanical accessories and is a removable connector. The nut is the nut, and bolts or screws screwed together used to play a fastening role in the parts; all production and manufacturing machinery must be used in a component according to the different materials, which are divided into carbon steel, stainless steel, non-ferrous metals (such as copper) and so on a few major types. Nuts are mechanical equipment with closely connected parts through the inner threads; the same specification nuts and bolts can be linked, such as M4-P0.7 nuts can only be associated with M4-P0.7 series of bolts (in the nut, M4 refers to the inner diameter of the nut is about 4mm, 0.7 refers to the distance between the two threaded teeth for 0.7mm); U.S. products are also the same, such as 1/4- 20 nut can only be paired with a 1/4-20 screw (1/4 refers to a nut ID of approximately 0.25 inches, and 20 refers to each inch in which there are 20 teeth). Stainless steel self-locking nuts, anti-loosening nuts, lock nuts, four-jaw nuts, screw-in nut safety nuts, thin rod screw connection nuts, self-locking hexagonal cap nuts, nuts for special ground screws, thin hexagonal disk nuts, and eyebolt nuts. Fine teeth all-metal hexagonal flange face lock nut, all-metal hexagonal flange face lock nut, fine teeth non-metallic insert hexagonal flange face lock nut, fine teeth hexagonal flange face nut, welded square nut, welded hexagonal nut, fastening nut, inset round nut with slot round nut, side with hole round nut, end face with hole round nut, small round nut, ring nut, butterfly nut. Copper nuts, inlaid copper nuts, knurled copper nuts, embedded copper nuts, injection molded copper nuts, alloy zinc-copper alloy nuts, etc. According to different occasions of use and requirements, nuts can be divided into various types.

1. Conventional nuts: Conventional nuts are the most common. It is shaped as a hexagonal cylinder with six corners and is usually used for mechanical fixing and connection. It is widely used because of its simple structure and low production cost.

2. Lock nut: A lock nut is a special nut. It has a circle of adjustable metal spacers on the top, which can be adjusted by adjusting the spacer's thickness to increase the nut's tightening force. The lock nut is mainly used for mechanical operation and must withstand significant vibration to ensure that the mechanical parts of the fixed will not be loose.

3. Flange nut: A flange nut is a kind of flange that uses a nut. It has a round protruding part at the top, which can be used in conjunction with the groove of the flange to ensure the fixation of mechanical parts. Flange nuts are generally used to connect equipment such as pipes and valves.

4. Self-locking Nut: A self-locking nut is a type of nut that can lock automatically. It has a curved metal piece on the top that can close the nut through elastic deformation. Self-locking nuts are usually used in mechanical parts that need to withstand tremendous shock and vibration.

5. Threaded pipe fitting nut: Threaded pipe fitting nut connects threaded pipes. It is threaded at the top and can be used with threaded pipes. Threaded pipe-appropriate nuts are generally used to connect gas, water, oil, and other pipes.

6. Long Nut & Heavy Duty Nut: A long nut is a long nut with a longer length. It is usually more than twice the length of a conventional nut and can be used to connect thicker mechanical parts. Long nuts are generally used when mechanical parts are subjected to more significant pressure.

7. Conical Nut: A conical nut is a tapered nut usually used to connect conical mechanical parts. Its conical design can improve the fixing force and make the mechanical parts more solid.

8. Countersunk Nut: A countersunk nut has a countersunk head. The countersunk head is recessed, allowing the top of the nut to be flush with the surface of the mechanical component for a tighter connection.

These are the common types of nuts. Different types of nuts are suitable for additional mechanical fixing and connection occasions. When selecting nuts, you need to choose the appropriate nut type according to the requirements of mechanical components and the use of occasions to ensure the quality of mechanical components fixed and connected.
