Quick answer: line up the holes in every layer, make sure the centre pin is raised, push the rivet body straight through until the head sits flat, then press the pin flush with your thumb. If the pin won't go flush, stop and check the hole size and the panel stack rather than forcing it. A removed push rivet can be reused if its legs are straight, its head is uncracked and its pin still locks firmly.
Push rivets are one of the simplest fasteners there is, but a few small mistakes cause most of the "my clips keep falling out" problems. This guide covers the right technique and how to decide whether an old clip deserves a second life.
How a push rivet locks
A two-piece push rivet has a body (head plus split legs) and a centre pin. With the pin raised, the legs are free to close, so the body slides through the hole. Pressing the pin down drives it between the legs and spreads them behind the panel. The panel is now clamped between the head and the spread legs.
That means two things must be right: the legs must pass fully through all the layers, and there must be enough room behind for them to spread.
What you need
- Replacement rivets of the right hole size and grip range. See the size guide and grip range guide.
- A trim tool or small screwdriver, for nudging panels into line and for raising pins.
- A rag to clean around the holes.
Step-by-step installation
- Clean the area. Grit and mud behind a panel stop it sitting flat, which puts the rivet under tension.
- Raise the pin. New rivets usually arrive with the pin up. If it is down, lift it with a fingernail or a trim tool until the legs move freely.
- Align every layer. Look through the hole; you should see straight through all of them. Nudge the panel with a trim tool rather than forcing the rivet to do it.
- Push the body through. Press straight in, square to the panel, until the underside of the head sits flat.
- Press the pin flush. Use your thumb. The pin should finish level with the head, or very slightly below.
- Tug-test. Pull gently on the head. It should not move, spin or click.
Common installation mistakes
| Mistake | Symptom | Fix |
|---|---|---|
| Pressing the pin before the head is flat | Legs spread inside the hole; rivet sits proud | Lift the pin, reseat the body, then press |
| Holes not aligned | Rivet goes in at an angle; panel cracks | Line up the holes first |
| Stack too thick for the rivet | Pin won't go flush | Re-measure; you may need a longer fastener |
| Stack too thin | Rivet spins and won't lock | Check for missing layers or an enlarged hole |
| Hole too big | Rivet pulls straight out | Repair the hole or use a wider head or washer |
| Hammering the pin | Cracked head, pin pushed through | Thumb pressure is enough |
Installing on different vehicles
- ATVs and UTVs: fender and floor panels often overlap. Start at one end and work along, so the overlap doesn't push earlier holes out of line. See our ATV and UTV fastener guide.
- Cars and trucks: wheel-well liners and splash shields hang best when you start with the top clips. Our fender liner clips guide has the full sequence.
- Cold weather: nylon gets stiffer when cold. Warm the rivets in your pocket before installing on a snowmobile or in a cold garage.
Can you reuse push rivets?
Often, yes. Use this checklist on each one:
- Legs: straight, complete and springing back together when the pin is raised.
- Head: no cracks, chunks missing or warping.
- Pin: present, not bent, and it clicks or firms up when pressed.
- Locking test: install it in a spare hole or the original hole and tug. If it pulls out, bin it.
Clips that have been in service for years, especially in sun, salt or heat, are worth replacing even if they look fine. Plastic that has gone chalky or brittle can snap the next time it is removed.
Replace in sets
If several clips on a panel have failed, the rest are usually not far behind. Replacing all of them at once saves pulling the panel twice. Our 8mm nylon push rivets come in bulk packs for exactly that, and 8mm automotive push rivets suit liners and bumpers. Both have an 8mm shank, 15mm head and 21mm length.
Installing in a new hole
If you are adding a mounting point, for example on a custom panel or an accessory bracket, drill the hole to the rivet's stated hole size. For our 8mm rivets that is an 8mm or 5/16" hole. Deburr both sides so the legs pass cleanly, and check the total stack is inside the grip range before drilling the matching hole in the second layer.
Every 8mm option we stock is grouped in one place: the 8mm push rivets collection.
FAQ
Do I need a tool to install push rivets?
No. Thumb pressure is all it takes. A trim tool helps align panels and raise pins.
Why won't my push rivet lock?
The hole is too big, the stack is too thin, or the pin was pressed before the body was seated. Lift the pin and reseat it.
Which way does the pin go?
The pin sits in the head on the outside of the panel. You press it inwards, towards the panel.
How do I remove a push rivet I just installed?
Lift the centre pin a few millimetres, then lever the body out. See our removal guide.
