What are the general specifications of hex nut standard parts?

As a standard part, it should have its own common specifications

For hex nuts, the commonly used standards are: GB52, GB6170, GB6172 and DIN934. The main differences between them are: GB6170 thickness is thicker than GB52, GB6172 and DIN934, commonly known as thick nuts. The other is the edge of the difference, M8's nut series DIN934, GB6170, GB6172 on the opposite side is 13MM than the GB52 on the opposite side 14MM to be smaller 1MM, M10 nut, DIN934 and GB52 on the opposite side of 17MM, than GB6170 and GB6172 on the opposite side of the larger 1MM, M12 nut, DIN934, GB52 on the opposite side of the 19MM than the GB6170 and GB6172 on the opposite side 18MM to 1MM. For the M14 nuts, the opposite side of DIN934 and GB52 is 22MM larger than that of GB6170 and GB6172. The other is the M22 nut, DIN934, GB52 on the opposite side of the 32MM, than the GB6170, GB6172 on the opposite side of the 34MM to 2MM. (Except for the thickness of GB6170 and GB6172, the width of the opposite side is exactly the same.) The remaining specifications can be used without considering the thickness.

1. Ordinary Hexagon - widely used, characterized by a relatively large fastening force, the disadvantage is that there must be enough operating space in the installation, you can use a live spanner, open end wrench or glasses wrench when installing, the above wrenches need to be large The operating space.

2. Cylindrical head Hexagon - is the most widely used of all screws, because of its relatively large fastening force, can use the Allen wrench to operate, very convenient when installed, almost used in a variety of structures, the appearance of a more beautiful, The disadvantage is that the fastening force is slightly lower than the outer hexagon, and the repeated use of the inner hexagon causes the inner hexagon to be unable to be disassembled.

3, pan head Hexagon - rarely used on machinery, mechanical properties as above, mostly used in furniture, the main role is to increase the contact surface with the wooden material and increase the appearance of ornamental.

4. Headless Hexagon - Some structures must be used, such as a top wire structure that requires a lot of top tension, or a place where the cylinder head needs to be hidden.

5, countersunk head Hexagon - mostly used in power machinery, the main role of the same with the internal hexagon.

6、Nylon Locking Nut—Inlaid with a nylon rubber ring in the hexagonal surface to prevent the loose structure of the thread, and it is used on strong power machinery.

7, flange nuts - mainly play a role in increasing the contact surface with the workpiece, mostly used in the pipeline, the fastener has been some stamping parts and castings.

8, ordinary hex nut - the most widely used, is also one of the most common fasteners.
