Seat Mounting Thread Stripped

[nigelj77]

Hi all,

I've had my 111R for a month or so now and am really enjoying it, the experience was a little spoiled by play in the drivers seat runners so as per something I read on seloc I removed the seat and squeezed up the gap in the runners.

The issue I now have in that on refitting it I have stripped the rear mounting hole in the floor of the car.

I'm wondering what the best fix for this is, I'm an engineer and am aware there are a number of potential solutions but what I don't know is how thick the raised aluminium section into which the seat bolts are attached is, any ideas?

If it's solid of heavy wall then I suspect it could be helicoiled or I could drill the hole out further and fit a threaded bush / adaptor.

If it's thin wall then some rivnuts and bracketry may be required.

Any advise would be appreciated.

Cheers,

Nigel

Thanks for your try junks.

Current status is I bonded the bolt into the stripped hole with epoxy resin, it seems rock solid but it's something I think should be mechanically fixed.

I spoke to a couple of garages who've suggested drilling right through the floor and add-ons a nut and washer to secure a longer fixing bolt.

The epoxy seems to have such a hold I'm not sure how easily it will come out to be honest...

This sounds more positive then at least it won't be a one off having a nut and bolt on the underside.

I have to say a tapped hole in relatively thin aluminium seems like a pretty poor design.

Cheers for the replies.
