Rivet guns are essential tools across a wide range of Australian industries, from metal fabrication and automotive repair to construction, roofing, and DIY projects. When used correctly, a rivet gun creates strong, permanent joints that are reliable and visually neat. However, incorrect use can lead to weak fastenings, damaged materials, or personal injury.
This guide explains how to use a rivet gun safely and correctly, covering preparation, step-by-step operation, safety precautions, and best practices to ensure professional results every time.
What Is a Rivet Gun?
A rivet gun (also known as a pop rivet gun) is a hand-operated or powered tool designed to install blind rivets. Blind rivets are fasteners that can be installed from one side of the material, making them ideal when access to the rear is limited.
Rivet guns are commonly used to join:
- Metal sheets
- Aluminium panels
- Plastic components
- Thin timber or composite materials
They are particularly popular in Australian workshops and job sites due to their durability, ease of use, and consistent performance.
Choosing the Right Rivet and Rivet Gun
Before using a rivet gun, it is important to select the correct rivet and tool for the job.
Rivet Types
Rivets vary by:
- Material (aluminium, steel, stainless steel)
- Diameter and length
- Head style (dome, countersunk, large flange)
Ensure the rivet is compatible with the materials being joined and thick enough to clamp them securely.
Rivet Gun Types
Common options include:
- Manual rivet guns – suitable for light to medium-duty tasks
- Lazy tong rivet guns – provide greater leverage for repetitive work
- Pneumatic or battery-powered rivet guns – ideal for professional and high-volume applications
Using the correct tool reduces effort and improves accuracy.
Essential Safety Precautions
Safety should always be the first consideration when using a rivet gun.
- Wear safety glasses to protect against snapping mandrels
- Use work gloves for better grip and hand protection
- Ensure the workpiece is securely clamped or supported
- Keep fingers clear of the rivet head and tool jaws
- Inspect the rivet gun for damage before use
Never operate a rivet gun if it is damaged or malfunctioning.
Step-by-Step: How to Use a Rivet Gun Correctly
Prepare the Workpiece
Align the materials to be joined and mark the rivet positions. Drill holes slightly larger than the rivet diameter, ensuring they are clean and burr-free.
Accurate hole placement is critical for a strong and neat finish.
Insert the Rivet
Push the rivet through the aligned holes so the rivet head sits flush against the surface. The mandrel should protrude from the rear.
Load the Rivet Gun
Insert the mandrel into the rivet gun’s nosepiece until it is fully seated. Confirm the correct nosepiece size is fitted to match the rivet diameter.
Position the Tool
Hold the rivet gun square to the work surface. Keeping the tool straight ensures even expansion of the rivet body.
Operate the Rivet Gun
Squeeze the handles (or activate the trigger for powered models) until the mandrel snaps. This action pulls the rivet body tight, securing the materials together.
Remove the Mandrel
Once the mandrel breaks, release the tool and remove the spent mandrel from the rivet gun. Many modern rivet guns automatically collect broken mandrels for convenience and safety.
Common Mistakes to Avoid
Using a rivet gun incorrectly can compromise the strength of the joint. Avoid these common errors:
- Using the wrong rivet size for the material thickness
- Drilling holes that are too large or misaligned
- Holding the rivet gun at an angle during operation
- Applying excessive force after the mandrel has snapped
- Reusing damaged or bent rivets
Taking a few extra moments to prepare properly can prevent costly rework.
Maintenance and Care of a Rivet Gun
Proper maintenance extends the life of your rivet gun and ensures consistent performance.
- Clean the jaws and nosepiece regularly
- Lubricate moving parts as recommended by the manufacturer
- Store the tool in a dry environment
- Empty mandrel collection containers frequently
Well-maintained tools are safer, easier to use, and more accurate.
When to Seek Professional Advice
While rivet guns are straightforward to use, certain applications—such as structural connections or high-load environments—may require specialised rivets or tools. In these cases, consult a professional supplier or manufacturer to ensure compliance with Australian standards and safety requirements.
Conclusion
Learning how to use a rivet gun safely and correctly is an essential skill for both professionals and DIY users. By selecting the right rivet, following proper safety procedures, and using the correct technique, you can achieve strong, clean, and reliable joints across a wide range of applications.
Whether you are working in a workshop, on a construction site, or tackling a home project, a rivet gun, used properly, is a dependable and efficient fastening solution.
