Rubber nuts
I've just found out about the existance of these. They sound just the thing for replacing my riveted on undertray.
I was going to use rivnuts but rubber seems better to isolate the ally tray from the steel frame and also no other tool is needed to insert them.
Any one with experience of rubber nuts who can confirm their usefulness and staying power?
Cheers
John

Do you mean the things that hold motorbike screens to their fairing?

All of the bodywork on my car uses them (except bonnet) 3 years on with these and nylon washers and there's no gelcoat cracking arround the
fastening points.
I found a company that sold bags of 1000 m6 rubnuts for 20 quid, they all got sold in bags of 12 on ebay for £10 a bag. happy days!
sadly a bag of a 1000 now costs over a £200.
theyre comonly used to hold motorcycle fairings on. the only downside is the 10/12mm hole that you need to drill in what you insert them in being
larger than a riv nut or rivet.

hi
hi
i work in a quarry and some of the large electric motors use them for fixing on the fan cowel, in the past these have come loose but i think it was
from the vibration.they have been on for about 3 year tho without any problem. might be worth just checking them ever month to see if the work
loose.

We call them wellnuts at the bike shop, they are usually a brass thread in a rubber insert used for holding screens on.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I use these rubber fasteners for work.
Try JGPFixings.co.uk
look under cavity fixings.
I think this is probably the best price you will get.

Yes, those are the guys, similar on here

I've been also told they are good but need to watch out for corrosion of the captive nut preventing undoing. I think they will be fine for the
undertray on a competition car garaged in winter and well greased.
Larger holes won't be too much trouble as I can cut down from the number of rivets already there.
Thanks for your help

Yep, called wellnuts. I've used them for my undertray.

Just keep an eye on them over time. On my bike, being 19 years old, they tend to harden and consequently tear. Not much of a problem for me as I can
quite easily reach the inside of the screen and hold them. But when you put them in a tight spot....
They do work well though... just don't expect them to survive a lifetime.

Attaching a panel with compliant fixings means the panel adds no stiffness to the chassis.
