Installing small head rivet nuts is a crucial skill in various industries, from automotive manufacturing to DIY home improvement projects. As a trusted supplier of small head rivet nuts, I'm here to guide you through the process step by step. In this blog, we'll cover everything from understanding what small head rivet nuts are to the tools required and the installation procedure.
What are Small Head Rivet Nuts?
Small head rivet nuts, also known as threaded inserts or rivet nuts, are a type of fastener that can be installed into a material to provide a threaded hole. They are designed with a small, low - profile head, which makes them ideal for applications where space is limited. Unlike traditional nuts and bolts, rivet nuts can be installed from one side of the material, making them particularly useful for blind installations.
There are different types of rivet nuts available in our inventory, including Full Hex Rivet Nuts, Cylindrical Rivet Nuts, Blind Hole Rivet Nuts, and Knurled Rivet Nuts. Each type has its own unique features and applications, but the small head rivet nuts stand out for their compact design.
Tools Required for Installation
Before you start installing small head rivet nuts, you'll need to gather the necessary tools. Here's a list of what you'll generally require:
- Rivet Nut Tool: This is the most important tool for the job. There are different types of rivet nut tools available, including manual, pneumatic, and hydraulic. Manual tools are ideal for small - scale projects or DIY applications, while pneumatic and hydraulic tools are better suited for large - scale industrial applications.
- Drill and Drill Bits: You'll need a drill to create a hole in the material where the rivet nut will be installed. Make sure to choose the correct drill bit size according to the specifications of the rivet nut. Using the wrong drill bit size can result in a loose or improper installation.
- Deburring Tool: After drilling the hole, you need to use a deburring tool to remove any sharp edges or burrs from the hole. This will ensure a smooth installation and prevent damage to the rivet nut.
Preparation Before Installation
- Select the Right Rivet Nut: The first step is to select the appropriate small head rivet nut for your application. Consider factors such as the material of the base material, the required thread size, and the load - bearing capacity. You can check out our wide range of Small Head Rivet Nuts on our website.
- Determine the Hole Size: Refer to the manufacturer's specifications to determine the correct hole size for the rivet nut. Mark the location where you want to install the rivet nut on the material and use a center punch to create a small indentation. This will help prevent the drill bit from wandering.
- Drill the Hole: Using the appropriate drill bit, drill the hole at the marked location. Make sure to drill straight and keep the drill perpendicular to the surface of the material. After drilling, use the deburring tool to clean up the edges of the hole.
Installation Procedure
- Insert the Rivet Nut into the Tool: Open the jaws of the rivet nut tool and insert the small head rivet nut into the tool. Make sure the rivet nut is properly seated in the tool and that the threads are aligned correctly.
- Position the Tool Over the Hole: Place the tool with the rivet nut over the drilled hole in the material. Ensure that the rivet nut is centered in the hole and that the tool is perpendicular to the surface of the material.
- Begin the Installation Process: If you're using a manual rivet nut tool, start turning the handle clockwise. As you turn the handle, the tool will pull the mandrel into the rivet nut, causing the rivet nut to expand and form a tight fit in the hole. If you're using a pneumatic or hydraulic tool, follow the manufacturer's instructions for operating the tool.
- Complete the Installation: Continue applying pressure until the mandrel breaks off at the break - point. This indicates that the rivet nut has been properly installed. Remove the broken mandrel from the tool and inspect the installation. The rivet nut should be firmly in place, and the threads should be clean and undamaged.
Troubleshooting
- Rivet Nut Not Expanding Properly: This could be due to using the wrong size drill bit or a damaged rivet nut. Check the hole size and replace the rivet nut if necessary.
- Mandrel Not Breaking Off: If the mandrel doesn't break off after installation, it may be because the tool is not applying enough pressure. Try increasing the pressure or check if the tool is functioning correctly.
- Rivet Nut Loose in the Hole: This may be a result of using the wrong size hole or a damaged rivet nut. Redrill the hole to the correct size and install a new rivet nut.
Applications of Small Head Rivet Nuts
Small head rivet nuts have a wide range of applications. In the automotive industry, they are used to attach various components such as interior panels, brackets, and wiring harnesses. In the aerospace industry, these rivet nuts are used due to their high - strength and lightweight properties.
