A2 - 70 Gread Heavy Hex Head Nuts For Industry , Custom Steel Hex Nut

A2 - 70 Gread Carbon Steel black PTFE Coated heavy hex nut for Industry

1. Product Description

For hexagon nut, commonly used standards are: GB52, GB6170, GB6172 and DIN934, for the main differences between them are: GB6170 thickness than GB52, GB6172 and DIN934 to the thick, commonly known as thick nut.Another is the difference on the side, M8 nut series DIN934, GB6170, GB6172 side are 13MM than GB52 side 14MM smaller than 1MM, M10 nut, DIN934 and GB52 side for 17MM, than GB6170 and GB6172 side for 1MM, M12 nut, DIN934, GB52 side for 19MM than GB6170 and GB6172 side for 18MM to 1MM.For the M14 nut, nut specification table is specific and detailed to unify all kinds of nuts, use the table to subdivide some specifications of nuts.There are many kinds of nuts and there are different kinds of nuts.Each type of nut has a different specification, each screw also has its mechanical properties and functions.The opposite side of DIN934 and GB52 is 22MM 1MM larger than the opposite side of GB6170 and GB6172 21MM.In addition is the M22 nut, DIN934, GB52 side for 32MM, than GB6170, GB6172 side 34MM smaller 2MM.(GB6170 and GB6172 have the same opposite width except for their different thickness) the other specifications can be universal without considering the thickness.

3. Application

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.
