Product Description

Square Welding Nut

The main materials for square nuts are carbon steel and stainless steel. Carbon steel nuts are usually used in ordinary scenarios and are relatively inexpensive; Stainless steel nuts are often used in corrosive or humid environments to prevent rusting. They all have high strength and durability, ensuring the stability and safety of the connection. The commonly used specifications range from M4 to M10, but can also be customized according to the specific needs of customers. This type of nut has a wide range of applications, whether in power engineering construction, road traffic, or the home building materials industry, its presence can be seen. They achieve a sturdy connection through welding, which is not easy to loosen, greatly improving the safety and stability of the connection.

Resistance welding is a process by where current and pressure are used to bond two pieces of metal. Resistance welding requires force in the bonding process. Pressure is used to hold two pieces of metal together while they are cooling. This also allows for the metals to properly bond together. The necessary pressure for the bonding process is typically applied by the machine or manually by the operator.
Square weld nuts feature four precision weld projections located on the head. This design allows for attachment of the fastener on the topside of the panel. The four equispaced projections are of equal height and size allowing for a properly balanced and positioned weld. 
Square weld nuts are designed for through-hole applications and are not self-locating, so require additional jigging or a locating pin for accurate placement during installation.  
Square weld nuts are available in a range of thread sizes, manufactured from steel and stainless steel and are suitable for use with compatible panel materials. 
Square weld nuts require appropriate resistance welding equipment for attachment.
