Handan strong Fastener Manufacturing Co., Ltd. is a professional manufacturer of all kinds of nuts. Do you know the classification of six angle nuts? Here is a brief introduction: I hope to help you. The six corner nuts are divided into three types according to the nominal thickness: I, II and thin. The nuts of Grade 8 or above are divided into 1 Types and two types of II type. The I type six nut nut is the most widely used, the 1 nut is divided into A, B, and C three, of which a and B nut are suitable for small surface roughness, high precision machine, equipment and structure, and C nut is used for machine, equipment or structure with rough surface and low precision, and the thickness ratio of 2 type six angle nuts. It is thicker and often used in occasions where it is often required to be dismantled. The 1 type nut refers to the ordinary six angle nut with a nominal height m equal to or equal to 0.8D. The size of the nut shall conform to the requirements of GB/T6170. The height of the 2 type nut is higher than that of the 1 type nut, and the size of the type nut should conform to GB/T6175. There are two purposes for adding type 2 nuts: one is to obtain a cheaper nut without heat treatment by increasing the height of the nut. Because the D 8 M16 1 type nuts do not need heat treatment, only 8 D>M16~39 nuts are used in the 8 grade nuts. Obviously, the 1 type nuts without heat treatment can not meet the mechanical performance requirements of grade 9 nuts. A 12 grade nut with better toughness is provided for another purpose of type 2 nut. As the height of the nut increases, the stress can be guaranteed at lower quenching and tempering hardness, so the toughness of the nut is increased. According to the classification of teeth: standard teeth, regular teeth, fine teeth, very fine teeth and reverse teeth. According to material classification: stainless steel six angle nut and carbon steel six angle nut, copper six angle nut, iron six corner nut. According to thickness classification: six angle thick nuts and six angle thin nuts. Classified according to usage: hot melt copper nut, hot pressed copper nut, embedded copper nut and ultrasonic copper nut. Handan Hao strong Fastener Manufacturing Co., Ltd. mainly produces: national standard nut, new national standard nut, British nut, American nut, high strength nut, nut, nut, flange nut, loose nut, six angle bolt and so on.
