1. Product Description
Hexagon nuts according to the nominal thickness divided into I type, II type and thin three.Nuts of class 8 and above are divided into type I and type II.
Type I hexagon nut is the most widely used, type 1 nut is divided into A, B, C three grades, among which A class and B class nut is suitable for the surface roughness is small, high accuracy requirements of the machine, equipment and structure, and C class nut is used for the surface is relatively rough, accuracy requirements of the machine, equipment or structure;Since class 8 type I nuts with D≤M16 do not require heat treatment, type 2 nuts are only used for class 8 nuts with D>M16~39 specifications.
Apparently type I nuts without heat treatment do not meet the mechanical requirements of class 9 nuts.Another purpose of the type II nut is to obtain a grade 12 nut with better toughness.As the height of the nut increases, the guaranteed stress index can be reached under the lower quenching and tempering hardness, so the toughness of the nut is increased.Material: 40Cr, 45 steel, 35K, stainless steel, Q235 (A3 steel) hardness grade: 4, 5, 6, 8, 10, 12

1, the common six corners outside the world -- widely used, characterized by relatively large fastening force. The drawback is that there must be enough space for operation when installing. When installing, you can use live wrenches, open wrenches or glasses wrenches. The spanner needs large space for operation.
2, the cylinder head inside hexagonal-is the most widely used of all screws, because it is relatively large fastening force, the use of hexagonal wrench can be operated, easy to install, almost all kinds of structures. The appearance is more beautiful and neat, the disadvantage is that the fastening force is slightly lower than the outer hexagon, and it is easy to damage the inner hexagon after repeated use.
3, inside the disk head hexagonal-rarely used mechanically, mechanical performance is above, mostly used in furniture, the main role is to increase contact with wooden materials and increase the appearance of the ornamental.
4, a headless six angle - some structures must be used, such as a top wire that requires a large top force, or a place where a cylindrical head needs to be hidden.
5. Hex of countersunk head-mostly used in power machinery, the main action is the same as the inner hexagonal.
Nylon lock nut-insert nylon rubber ring in hexagonal plane to prevent thread loosening structure, strong power mechanical use.
7, flange nut - mainly to increase the effect of contact with the workpiece, mostly used in pipes, fasteners have some stamping parts and casting parts.
Ordinary hexagonal nuts-most widely used, but also one of the most common fasteners.
