Hex Steel Nut Threading technology
Hex nuts are parts that are tightly connected to the machine and can be connected together by the inner threads, the same size nuts and screws.
Nuts a wide variety, we are common GB, British standard, American standard, the standard nut. Nuts according to the different materials, divided into carbon steel, high strength, stainless steel, steel and other major types. According to product attributes corresponding to different countries Standard number is divided into ordinary, non-standard, (old) GB, the new national standard, US, British, German standard. Different sizes, different threads are divided into different specifications. General GB, German standard with M said (such as M8, M16), the United States, the British system with the score or # that specifications.
Nuts are nuts, screwed together with bolts or screws used to fasten the role of the parts, all manufacturing machinery must use an original. Nuts a wide range, we have a common GB, British standard, American Standard, Japan The nuts are divided into carbon steel, high strength, stainless steel, steel and other types according to the material, according to the product attributes corresponding to different national standard number is divided into ordinary, non-standard, (old) GB, the new national standard, , British, German standard. (Such as M8, M16), the United States, the British system with the score or # that specifications (such as 8 #, 10 #, 1/4, 3), the size of the different, different threads are divided into different specifications. /8)
The definition of hex nuts
Hex nuts and bolts, screws with the use of fastening machine from the role of connection. Which by the first type of six nuts with the most widely used, C-class nuts for rough surface, the accuracy requirements of the machine is not high, equipment or structure; A and B-class nuts for the surface is relatively smooth, high precision Of the machine, equipment or structure. Type 2 hexagon nut thickness M thick, mostly used often often need to wear and tear of the occasion. The thickness M of the hexagonal thin nut is thin and is used for the case where the surface space of the connected part is restricted. Thread technology has gradually entered a number of areas including aircraft, cars, trains, railways, ships, construction, machinery, oil, agricultural machinery, electricity, military, medical equipment and other fields. This is a successful example of the successful use of American aerospace technology to civilian industry, a revolution in traditional threading technology.
With the anti-loose nuts in China gradually increase the user, the scope of application gradually expanded, there have been some new application examples. In order to facilitate the use of the majority of users to promote the above seven cases for the majority of users reference.
Loose nuts have been loaded into the domestic institutions of higher learning mechanical design disciplines of university unified textbooks, published by the Higher Education Press, edited by Peng Wensheng, "mechanical design," a book will be loose nuts and spring washers, Metal pre-stressed nuts and nylon nuts and other four other technologies tied to the five major thread-locking technology. Lock nuts and product standards are also included in the Chemical Press's mechanical design manual.
