Chapter 1: What are Push Nut Washers?
a. Definition and Functionality
Push nut washers, also known as push-on nuts or push nuts, are ingenious fasteners designed to secure components without the need for threaded holes or external tools.
They consist of a circular, flat washer with internal teeth that grip onto the mating surface when pressure is applied.
This unique design allows for quick and efficient assembly, making them popular in various industries and applications.
Push nut washers are commonly made from materials such as steel, stainless steel, brass, or nylon, providing durability and resistance to corrosion.
The internal teeth create a firm and reliable hold on the mating surface, preventing the components from coming loose or vibrating during use.
b. Types of Push Nut Washers
There are several types of push nut washers available, each designed to suit specific applications:
i. Internal Push Nut Washers
Internal push nut washers are used when a secure fastening point is required inside a hollow shaft or tube. They are inserted into the shaft or tube and expand when pressure is applied, locking them firmly in place.
ii. External Push Nut Washers
External push nut washers are used when a secure fastening point is required on the outside of a shaft or stud. They are pressed onto the outside surface of the shaft and grip onto it with their internal teeth.
iii. Flanged Push Nut Washers
Flanged push nut washers have an extended flange around the perimeter, providing additional support and preventing the push nut from sliding too far onto the mating surface.
c. Applications
Push nut washers find application in a wide range of industries due to their simplicity, effectiveness, and cost-efficiency. Some common applications include:
i. Automotive Assembly
- Securing hubcaps onto wheels.
- Attaching trim and molding pieces.
ii. Electronics
- Holding knobs and switches in place.
- Securing panels or components.
iii. Furniture Manufacturing
- Assembling drawers and cabinets.
- Securing joints in furniture frames.
iv. Construction
- Fastening panels, signs, or access panels.
- Joining metal or plastic components.
v. DIY Projects
- Quick and easy solutions for home repairs.
- Secure fastening for craft and DIY projects.
The versatility of push nut washers makes them an invaluable hardware solution for a wide range of projects, simplifying assembly and ensuring components stay securely in place.
Whether you’re working on an automotive project, electronics assembly, furniture manufacturing, or any DIY endeavor, push nut washers offer a reliable and efficient way to secure components without the need for threaded fasteners or complex tools.
Chapter 2: How to Install Push Nut Washers
a. Pre-Installation Preparation
Before you begin the installation process, it’s essential to gather all the necessary components and prepare the surfaces for a secure fit. Here’s what you should do before installing push nut washers:
Gather Components: Collect all the push nut washers you need for the project, ensuring they are of the correct size and type for your application.
Clean the Surfaces: Make sure the surfaces where the push nut washers will be installed are clean and free from any dirt, debris, or lubricants. A clean surface will ensure a strong and reliable grip.
Verify Sizing: Check that the push nut washer’s inner diameter matches the diameter of the mating stud or shaft. Using the wrong-sized push nut can result in a loose fit and compromised performance.
b. Step-by-step Installation Process
Now that you’re prepared, follow these steps to install push nut washers effectively:
Step 1: Position the Push Nut Washer
Place the push nut washer onto the desired shaft or stud, ensuring that the teeth of the washer face the surface where the pressure will be applied.
Step 2: Apply Pressure
With the push nut washer in position, apply steady pressure by pressing down on the washer. Depending on the application, you can use your fingers, the palm of your hand, or a tool designed for push nut installation.
Step 3: Firmly Seat the Washer
Continue applying pressure until the push nut washer is firmly seated on the mating surface. The internal teeth will grip onto the surface, providing a secure fit.
Step 4: Verify the Tight Fit
Check that the push nut washer is properly seated and that there is no play or movement between the washer and the mating surface. A tight fit ensures that the components will remain securely in place.
c. Tips for Ensuring a Secure Fit
To ensure the push nut washers provide a reliable hold, consider the following tips:
Use Proper Pressure
Apply enough pressure during installation to ensure a secure fit, but be careful not to over-compress the push nut washer, as this could damage the mating surface or compromise the washer’s functionality.
Avoid Rotation: If you are installing an external push nut washer on a shaft, be mindful of its orientation. Avoid rotating the push nut washer during installation, as this can cause misalignment and reduce its grip.
Adhesive or Thread Locker
If the application demands additional security, you can apply a small amount of adhesive or thread locker to the mating surface before installing the push nut washer.
This can prevent any unintended loosening over time.
Use a Push Nut Installation Tool
For large-scale projects or to ensure consistent and precise installations, consider using a push nut installation tool.
These tools provide controlled pressure and help avoid damage to the push nut or mating surface.
By following these installation steps and tips, you can effectively install push nut washers for various applications.
Their straightforward installation process and secure hold make push nut washers an excellent choice for quick and reliable fastening without the need for threaded holes or external tools.

Chapter 5: Alternative Method: How to Remove Rivet Nuts
a. Understanding Rivet Nuts
Before delving into the removal process, it’s essential to understand what rivet nuts are and why they require a different approach compared to push nut washers.
Rivet nuts, also known as threaded inserts or blind rivet nuts, are tubular fasteners with internal threads.
They are commonly used to create a threaded hole in materials like metal, plastic, or composites where access to the opposite side is limited or impossible.
Rivet nuts are installed by collapsing the shank inside the material, creating a secure and threaded fastening point.
b. Different Ways to Remove Rivet Nuts
Unlike push nut washers, removing rivet nuts can be a bit more involved due to their threaded nature and secure installation. Here are a few methods to consider:
Method 1: Drilling Out Rivet Nuts
Identify the Rivet Nut: Locate the rivet nut you wish to remove. Note that rivet nuts are often installed flush with the material surface or countersunk, making them more challenging to access.
Choose the Right Drill Bit: Select a drill bit that matches the rivet nut’s size or slightly larger to ensure you can drill through the rivet nut without damaging the surrounding material.
Drill Carefully: Drill through the center of the rivet nut until the shank is fully removed, and the threads are no longer gripping the material.
Remove the Rivet Nut: Once the shank is drilled out, the rivet nut should be easy to remove by hand or with pliers.
Method 2: Use a Rivet Nut Removal Tool
Obtain a Rivet Nut Removal Tool: Specialized rivet nut removal tools are available for efficiently extracting rivet nuts. These tools grip the rivet nut and facilitate its removal without damaging the material.
Position the Tool: Place the removal tool around the rivet nut, ensuring it grips the nut securely.
Apply Pressure: Squeeze the handles of the removal tool to apply pressure to the rivet nut and release its grip on the material.
Remove the Rivet Nut: Once the rivet nut is loosened, remove it by hand or with pliers.
c. Comparing Rivet Nuts to Push Nut Washers
While rivet nuts and push nut washers both serve as fasteners, they are used in different applications and require distinct methods for installation and removal:
- Rivet nuts are ideal when you need a threaded fastening point in materials where rear access is limited or impossible. They provide a strong and durable connection for components.
- Push nut washers are well-suited for quick and secure assembly in applications where threaded holes are not present or external tools are not desired. They offer a simple and efficient alternative to traditional threaded fasteners.
In summary, removing rivet nuts requires more effort than removing push nut washers due to their threaded nature.
By using drilling or specialized rivet nut removal tools, you can safely and effectively remove rivet nuts from materials without causing damage.
Remember to choose the method that best suits the specific rivet nut and material you are working with, and exercise caution to avoid any accidental damage during the removal process.
