Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Rivnuts are basically evil

Very probably - and/or a smear of copaslip on the threads. I tend to do this anyway as I usually use stainless fasteners into the rivet and want to avoid differential corrosion.

They are good for lower load applications but a small dab of locking fluid/ JBWeld adds security. A light smear of a grease like copper based stuff and stainless bolts adds to a better life. You can build up a nice stock of stainless bolts/screws etc quite cheaply. I use them to replace older fixings whenever needed. Car/ garden house etc. A2 grade is ok or A4 if needed. Never on high stress safety fittings though.
Haven’t used rivnuts for a long time but if set correctly they are handy. Easier than tapping holes.

Rivnut is good for me





the best tool is this one



there are all kinds of different on the last photo they are crenellated



they can be mounted with loctite 638 for bonding.

Blimey GLLOQ , I see the problem is with me .... gets coat.

I had the same thought! We are lucky indeed to have the world's foremost proponent of rivnuts on this forum!

I would love to have a video of these fine tools being used down in the footwell on the transmission tunnel cover.
