How to use rivet nuts
Rivet nuts are a common fastener and are widely used in machinery, automobile, electronics and other industries. It is simple to install, firm and reliable, and is suitable for connecting thin sheet materials. This article will introduce in detail the use of rivet nuts, classification and precautions to help you better master this tool.
1. Classification of rivet nuts
Rivet nuts can be divided into the following categories according to their material, shape and purpose:
| Classification criteria | type | Features |
|---|---|---|
| Material | Stainless steel rivet nut | Corrosion resistant, high strength, suitable for outdoor or humid environments |
| Material | Aluminum alloy rivet nut | Lightweight, low cost, suitable for lightweight design |
| shape | Round head rivet nut | After installation, the surface is flat and beautiful |
| shape | Hexagonal rivet nut | Anti-rotation, suitable for situations where high stability is required |
| use | Through hole rivet nut | Suitable for through-hole installation, commonly used in mechanical connections |
| use | Blind hole rivet nut | Suitable for blind hole installation, commonly found in closed structures |
2. Steps for using rivet nuts
Use of rivet nuts requires the following tools: rivet nut guns, rivet nuts, drilling tools (such as electric drills), and suitable drill bits. The specific steps are as follows:
1.drilling: Drill the hole at the position where the rivet nut needs to be installed. The hole diameter should match the outer diameter of the rivet nut, which is usually 0.1-0.2mm larger than the outer diameter of the rivet nut.
2.Insert rivet nut: Place the rivet nut into the drill hole to ensure it fits with the surface of the workpiece.
3.Install the riveted nut gun: Put the puller of the rivet nut gun into the thread of the rivet nut and make sure the puller is in full contact with the rivet nut.
4.Tighten the rivet nut: Tighten the handle of the rivet nut gun vigorously until the rivet nut is completely expanded and secured to the workpiece.
5.Check the installation effect: Make sure the rivet nut is installed firmly and there is no looseness.
3. Things to note about rivet nuts
1.Choose the right rivet nut: Select the material and size of the rivet nut according to the material, thickness and usage environment.
2.Control drilling accuracy: Too large or too small the drilling hole will affect the installation effect of the rivet nut, and it is recommended to use a special drill bit.
3.Avoid excessive tension: Excessive tightening may cause deformation of the rivet nut or damage to the workpiece, so appropriate force should be applied.
4.Regular inspection tools: The pull head of the rivet nut gun is prone to wear and needs to be replaced regularly to ensure installation quality.
4. Application scenarios of rivet nuts
Rivet nuts are widely used in the following fields:
| industry | Application scenarios |
|---|---|
| Automobile manufacturing | Fixing of body panels and interior parts |
| Electronic equipment | Installation of circuit boards and housings |
| Machinery manufacturing | Thin plate connection, bracket fixation |
| Furniture industry | Assembly of metal furniture |
5. Summary
Rivet nut is a simple and efficient fastener suitable for a variety of scenarios. Correct selection and use of rivet nuts can significantly improve work efficiency and connection strength. I hope that through the introduction of this article, you can better master the use of rivet nuts and flexibly apply them in actual work.
