And they have the fasteners at a decent price.

It did take some internet lurking to find it though.

For realy confined spaces I use a HT caphead bolt + 2 well fitted washers all well greased (flange type inserts,) For c/sunk type you need to turn a thick washer with a small cone .

I'm a bit thick Jugs. Got any pics? not sure wot you mean.

Rivnuts if not installed correctly can spin, and are not intended for continual use or high torque . Where this is likely these should be used Hexagonal type,

If you think the bolt will be installed/removed then a couple of tacks with the TIG should hold it fast

Not really intended for any torque resistance at all the standard type, however one way to increase the torque resistance without welding (you have a painted finish etc) is to either tap the hole and have a slight interference fit or cut small small teeth into a .25mm undersize hole using a small carbide burr, with a result similar to firearm rifling.

It would probably only resist 10's of Nm but it'll certainly help stop it turning if you need to tighten the bolt up.

I missed out on a FAR pneumatic tool for £20 recently.... it was well used and i didn't get it because the seller didn't know if it was complete, wish i had got it at that price and had a fiddle anyway!

Rivnuts have the same advantages and disadvantages as blind rivets really...use them as they are intended and they are brilliant, too many people abuse them!

There are some really low profile rivnuts with splined shanks for good grip.
