A hexagon weld nut, also known as a hex weld nut or a projection weld nut, is a type of nut with a hexagonal (six-sided) shape and a specially designed projection or boss on the backside. The projection allows the weld nut to be easily welded to another metal object, typically a metal plate or sheet, by creating a strong and permanent joint.
Here's how a hexagon weld nut works:
1. Shape: The top side of the hexagon weld nut has standard hexagonal wrenching flats, making it easy to tighten or loosen the nut using a standard wrench or socket.
2. Projection: On the backside of the nut, there is a small cylindrical or rectangular projection, which serves as a welding point.
3. Welding Process: The hexagon weld nut is positioned on the metal surface where the nut is to be attached. A welding process, such as resistance spot welding or projection welding, is then used to melt and fuse the projection of the nut with the metal surface, creating a strong and permanent bond.
4. Threaded Opening: After welding, the nut remains securely attached to the metal surface, and the threaded hole in the center of the nut can be used for fastening bolts or screws.
Hexagon weld nuts are commonly used in various applications, including automotive, construction, industrial equipment, and metal fabrication. They provide a reliable and efficient way to attach threaded fasteners to metal surfaces, especially in situations where it may be challenging to access the backside of the metal or where welding is the preferred method of attachment.
The availability of different thread sizes and materials (such as steel or stainless steel) allows hexagon weld nuts to be used in various environments and for different load-bearing requirements. They are particularly useful in applications where a strong and permanent threaded connection is needed without the risk of the nut becoming loose or falling off over time.
