American National Thread is widely used in regions and industries that are influenced by American industry. In World War II, due to the inconsistent thread standards used by the Allies, the logistical supply difficulties caused serious economic losses and casualties to the Allies.

Riveting is a method for combining two pieces of metal. Therefore, riveting technology is often used to fasten rivets such as nuts or rivets to metal sheets.

Existing bolt and nut connections usually use threads for connection, and this connection method has two main drawbacks. First, tools are required to be used to lock it during installation, and it takes a long time to complete, which is time-consuming and labor-intensive; Second, the installed bolts and nuts are prone to loosening after a period of time, resulting in loosening and shaking between the connecting parts. Therefore, there is a need for a bolt and nut fastener that is easy to install and can effectively prevent the loose fit of the bolt and nut, so as to solve the problems existing in the prior art.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: waterproof sealing rivet nuts, non-standard stainless steel bolts, GB55 hexagonal thickened nuts, flange nuts and other products, we can provide you with The right fastener solution for you.
