Weld nut

Abstract

A weld nut has a base panel and a nut. The base panel has a through hole formed through and multiple weld points formed on a bottom of the base panel. The nut is mounted securely in the through hole in the base panel and has a nut body, a connecting section and a threaded hole. The connecting section is formed on and protrudes axially from the nut body, is mounted securely in the through hole. The threaded hole is formed through the nut body and the connecting section to screw with a bolt. The base panel has a lower carbon content and has an excellent weldability to make the weld points easy to be welded on a workpiece. The nut has a higher carbon content and has an enhanced hardness to prevent deformation resulted from an axial force.

Claims

1. A weld nut comprising: a base panel having a top;a bottom;a through hole formed longitudinally through the base panel; andmultiple weld points formed on and protruding from the bottom of the base panel around the through hole; anda nut mounted securely in the through hole in the base panel and having a nut body having a distal end;a proximal end; andan outer wall;a connecting section formed on and protruding axially from the proximal end of the nut body, mounted securely in the through hole in the base panel and having a distal end;a stabilizing flange formed on and protruding radially form the outer wall of the nut body and havinga top; anda bottom abutting with the top of the base panel; anda threaded hole formed through the nut body and the connecting section.

2. The weld nut as claimed in claim 1, wherein the through hole in the base panel includes a polygonal recess formed longitudinally in the top of the base panel; anda circular recess formed longitudinally in the bottom of the base panel, communicating with the polygonal recess and forming a join surface between the circular recess and the polygonal recess; andthe connecting section further has an expanded flange formed on and protruding radially from the distal end of the connecting section and abutting the join surface between the circular recess and the polygonal recess.

3. The weld nut as claimed in claim 1, wherein the top of the stabilizing flange is tapered off toward the distal end of the nut body.

4. The weld nut as claimed in claim 2, wherein the circular recess is tapered off toward the top of the base panel.

5. The weld nut as claimed in claim 2, wherein the polygonal recess is a hexagonal recess; andthe connecting section is a hexagonal prism to be mounted correspondingly in the polygonal recess.

6. The weld nut as claimed in claim 1, wherein the nut body is polygonal.

7. The weld nut as claimed in claim 6, wherein the nut body is hexagonal.

8. The weld nut as claimed in claim 6, wherein the nut body is octagonal.
