Four Corner Weld Nut

Four corner weld nuts feature four protruding welding lugs around the square body, which act as positioning points during spot welding to prevent rotation and detachment after welding. The whole nut is cold forged for uniform texture and stable mechanical performance.

We offer two mainstream material options: galvanized carbon steel for general indoor use and stainless steel for damp or outdoor anti-rust scenarios. Every thread is finely processed to ensure consistent tolerance and reliable locking force. Standard metric specifications are in constant stock, and we can produce customized weld nuts according to your drawings, including changes to thread size, body thickness and lug height.

This type of weld nut is widely applied in automobile frames, communication cabinets, air conditioner housings and metal machinery parts, serving as a cost-effective fastener for permanent sheet metal connection. All finished goods pass dimensional and surface inspection before delivery to ensure stable quality for global buyers.
