Nut

The main functions of the nut include: Connection: the nut and bolt are combined to form a bolt connection, which is used to connect two parts, such as pipes, mechanical equipment, etc. Easy disassembly: By rotating the nut, the installed bolts can be easily removed for easy maintenance or replacement of parts. Corrosion protection: Many nut surface treatments, such as nickel plating or stainless steel, to enhance corrosion resistance.

What does a nut mean?

The nut is a fixed tool with a hole in the center and a spiral grain on the inside of the hole. Nuts are often shared with screws of the same size to hold the relevant joint. If environmental factors such as vibration cause the nut to loosen, tools such as glue or pins can be used to further strengthen the relevant part. The nuts are mostly hexagonal, followed by squares.

What are the categories of nuts?

There are many kinds of nuts, which can be divided into carbon steel, high strength steel, stainless steel, plastic steel and so on. According to product attributes and national differences, the standard number is divided into ordinary, non-standard, old national standard, new national standard, the United States, the United Kingdom, Germany and so on. Hexagonal nut thickness, hexagonal nuts are divided into type I, type II and thin type. Nuts greater than 8 grades can be divided into Class I and Class II.

What about nut specifications?

A common representation of metric threads is a combination of diameter and pitch. For example, M10x1.5, this means that the outer diameter of the nut is 10 mm and the distance (pitch) of the thread per turn is 1.5 mm. In addition, there is another representation method is the inner diameter plus thickness, such as M6-3H, where 6 represents the inner diameter and 3H is the accuracy level.
