Welding nut
Welding nut is an internally threaded fastener that can be directly welded to the surface of the workpiece. No drilling or tapping is required for welding fixation, which simplifies the processing process. It is integrated with the workpiece, has strong load-bearing capacity, and is suitable for heavy-load vibration environments. There is no risk of loosening after installation, and is suitable for permanent connection scenarios. It has a compact structure and is suitable for small installation spaces.

Main uses
Automobiles and engineering machinery: used in automobile chassis, frames, engine brackets, Excavator body parts are resistant to vibration and loosening after welding and fixation, and are suitable for long-term bumpy and heavy-load environments. They are one of the core fasteners in automobile manufacturing.
Machinery and equipment manufacturing: used for permanent connection of equipment shells, frames, conveyor frames, and workpieces without threaded holes to simplify the processing process. , improve the overall rigidity of the equipment and adapt to mechanical components that require high-frequency operation.
Building and steel structures: used for steel structure connectors, curtain wall keel welding and fixing, pipe supports. The carbon steel hot-dip galvanized version is corrosion-resistant, and is integrated with the steel structure after welding. It has strong load-bearing capacity and is suitable for heavy-duty construction. Scenarios.
Universal and special scenarios: used in furniture frames (metal materials), outdoor fences, agricultural machinery parts, stainless steel models used in chemical industry, marine equipment and other corrosion-resistant environments, blind hole type adapted to the connection requirements without penetrating the workpiece.
