Rear axle bolts/nuts for 172

Hi guys probably already discussed but what bolts are needed when the old ones are cut off the rear beam of a Clio mk2 172.
What tensile strength, length, diameter etc.
Any information would be a great help

Cheers Marcus

The bolt that goes through the bracket and bush is 7703002732 and uses an M10 bolt.

Kam Racing sell them here - https://www.kamracing.co.uk/renault-oe-rear-bush-retaining-bolt-nut-renault-clio-mk2.html

The bolts that go through the floor and into the bracket have captive retainers on them - 7703015200 but sadly NLA.

Those are a high tensile 10:9 M10 bolt 130mm in length with a 1.25 fine thread - you'd get the nuts from your local fasteners.

Thank you for all the above information that really is a great help. Will now concentrate on getting the rear beam removed, blasted, and painted,
Cheers again

You’re welcome.

When replacing the floor-to-bracket bolts, ensure the bolts have sufficient threading.

When I first replaced my rear beam, I bought some bolts from Cromwell to save money. Unfortunately, these bolts didn't have enough thread, so I had to temporarily use a bunch of washers until the factory bolts arrived. See the attached pictures for reference.

Aftermarket bolt on the left with a lot of washers. Factory bolt to the right with single washer.



Factory bolt and aftermarket bolt side by side.



In hindsight it would have been easier to walk into my local fasteners with the original bolt and asked them to match as close as possible. Buying online can be more difficult.

Yes that's true. Quite lucky there is a nuts and bolt company not to far away which carry a huge stock.
I have the same powerflex bushes to fit when the beam is finished.
Cheers for the pic etc 👍
