stainless steel ss304 custom Heavy Iron Hex head Nuts A2-70 / 80
1. Product Description
A nut is a fastener with internal threads and used in conjunction with a bolt, a mechanical part with internal threads and used in conjunction with a screw to transfer motion or power.
1,Common outer hexagon - the application is more extensive, the characteristic is the fastening strength is quite big, the shortcoming is when the installation wants to have the enough operation space, when the installation may use the live spanner, the open spanner or the glasses spanner, the above spanner needs the very big operation space.
2, cylinder head hex - is the most widely used in all the screws, because it is fastening force is larger, can use Allen key operation, the installation is very convenient, when used in almost all kinds of structure, appearance is beautiful and neat, faults is slightly lower than outside hexagonal fastening force, also repeated use can't remove the socket head broken easily.

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.
