Plastic vs metal pop rivets for car panels

3 min read · Clip types explained

Pop rivets join two parts from one side. On cars you will see two kinds: plastic (nylon) rivets that hold trim and liners, and metal blind rivets that hold brackets and fittings. They are not interchangeable.

Plastic pop rivets

A plastic pop rivet has a split nylon body and a long pin. Setting the pin spreads the body behind the panel. They are light, will not rust, and are easier to remove later. Use them on mud flaps, arch liners, trim and light panels. See plastic pop rivets.

Metal pop (blind) rivets

A metal blind rivet is set with a rivet gun. The mandrel pulls the body tight behind the panel and snaps off. They are stronger and permanent. Use them for brackets, heat shields and fittings such as fuel lids. See metal pop rivets.

Sizing either type

• Diameter: must suit the hole (for metal rivets, the drill size).
• Length: must suit the total thickness you are joining.
• Head size: bigger heads spread the load on soft material.

Our product pages list the sizes shown on each photo. See how to measure a car clip.

Removing old rivets

Drill out metal rivets through the head with a bit just smaller than the rivet, then tap the rest out. For plastic rivets, cut or lift the head and push the body through. Try not to make the hole bigger, or the new rivet will be loose.

Which one should I use?

Use what the car came with. If a plastic panel was riveted with plastic, a metal rivet can crack it. If a bracket was metal riveted, a plastic one will not be strong enough.

When to choose each

Drilling out a metal pop rivet

1. Use a drill bit the same size as the rivet stem.
2. Drill through the head only, keeping the drill straight.
3. Knock the rest of the rivet through and clean the hole.

Pop rivet sizes in our range

Our plastic pop rivets have stems of about 4 to 7 mm. Our metal pop rivets have stems of about 4 to 6 mm. The stem size is the drill size you need, so check it before you drill out an old rivet.

Sizes are approximate, read from the measurement marks on our product photos. Always compare with your original part.

Frequently asked questions

Can I replace a metal pop rivet with a plastic one?

Only where the joint does not need the strength of metal, such as a trim. Keep metal rivets on load-bearing joins.
