1. Product Description

Hexagon nuts are used in conjunction with bolts and screws to connect and fasten the mechanical parts. Type 1 Hexagon nuts are most widely used for rough surfaces. A machine, device, or structure that does not require high precision; Class A and B nuts are used in machinery, equipment or structure whose surfaces are smooth and clean, and the thickness m of type .2 hexagonal nuts is thicker. Hexagon thin nut has a thin thickness m and is mostly used in cases where the surface space of the connecting parts is limited.

Common color, blackening, galvanizing are ordinary carbon steel nuts.Nuts generally have a performance rating.Stainless steel is usually 2-70.Separate the carbon steel nuts and stainless steel nuts from the magnets.Stainless steel will not be absorbed by the magnet.Stainless steel products are usually bright silver.

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.
