Spot Weld Nut

Weld nuts with 2 projections are fasteners designed specifically for resistance spot welding, characterized by two precise engineering protrusions on the nut body. When these protrusions come into contact with metal plates, they melt at high temperatures generated by current to form solder joints, thereby achieving permanent and high-strength connections.

Structural characteristics of T Welded Nuts :

The corresponding Chinese for "T type weld nut plate" is T type welded nut plate, which is essentially a type of plate-shaped fastening accessory that integrates T type welded nuts. It is often referred to as T cap plate, and its core function is to be fixed on the substrate by welding, and to achieve tight connection between components by cooperating with bolts or screws.


Core structure and design advantages


Structural features: The overall structure is T-shaped, consisting of a nut body with internal threads and a plate-shaped base. Some products may have welding protrusions on the base. This structure can expand the contact area between the plate-shaped base and the substrate to achieve uniform force distribution, and can also adapt to narrow channels, grooves, and other confined spaces through T-shaped modeling, solving the problem of circular base nuts being unable to be installed in special scenarios.


Production process: The mainstream adopts wire cold heading forming process, and the internal threads of nuts are mostly made by reciprocating rotary tapping. This process can ensure high tolerance accuracy of products and stable production efficiency; For non-standard specifications, customized processing can also be carried out through multi-mode stamping equipment to meet different size requirements.


Material and surface treatment: The material is mainly carbon steel, but there are also materials such as 302, 304 stainless steel, and brass to choose from, suitable for different corrosion resistance and strength requirements scenarios.


Common surface treatment methods include color zinc plating, white zinc plating, blue white zinc plating, nickel plating, etc., to enhance corrosion resistance and extend service life.


Key specification parameters: The conventional outer diameter covers the range of M6-M10, and longer sizes can also be customized according to customer needs;

Application: 

The automotive and home appliance industry: Due to the strong connection after welding, it is commonly used for fixing parts of car compartments, electric vehicles, as well as sheet metal structure connections of household appliances such as refrigerators and washing machines, meeting the requirements for fastening stability and durability in these fields.

In the field of furniture manufacturing, it is a commonly used accessory for panel furniture and office furniture, such as sofas, child beds, cabinets, etc. It can be embedded in boards or frames and connected with screws to achieve component splicing.

General Machinery and Other Fields: It is widely used in the fixing of shells and internal parts of mechanical equipment and pneumatic tools, as well as in the structural assembly of medical devices and sports equipment. Some of it can also be used in scenarios such as steel structures and pipeline auxiliary fixing.

Core usage characteristics

During installation, it is necessary to weld on a flat and uncoated metal surface. The welding protrusions on the base can concentrate heat, help weld more firmly, and form a permanent connection; And there is no need for additional gaskets, the installation steps are simple.


Compatible with standard metric bolts and screws, with strong versatility, and can be removed by processing solder joints with specialized tools during disassembly, balancing connection stability and convenience for later maintenance.
