Reading this forum, there's lots of mentions of "RivNuts".

I'd previously never heard of these things.

A quick search on google shows pictures of Rivnuts, but I couldn't quite see how they worked...




On further investigation, I found a video! Woohoo!! All is clear.

Rivnut Video

You use a rivnut tool, which has a threaded shank that you screw into the rivnut. The rivnut then goes into your drilled hole and the tool works like a pop rivet tool to pull on the threaded shank. This action deforms the lower part of the rivnut against the inside of panel or tube until it's securely fixed in place. Then you unscrew the shank to leave the rivnut in place.

Hope that makes sense, but I'm sure there must be pictures on here somewher that would show it.

There is a sectional side view on this website

Basically they work on the same principal as POP rivets but using a dedicated tool that has interchangeable threaded adaptors to 'set' the different thread size rivnuts, the threaded adaptor being the equivalent to the snap off pin in a POP rivet, the difference being that the threaded adaptor does not snap off it has to be unscrewed after the rivnut is 'set'.

Here's a picture of the hand tool

Cheers for the information guys - but I know that now, that's why I posted that video!!! (See my first post)

Cool vid!

You mistake was putting the vid at the bottom of the post- I'm guessing that many long-term LB'ers (myself included) tend to subconsciously skip the bottom of a post as it's usually someone's signature! That's why I missed it on 1st read anyway!

a-HA! Good advice, I'll make it a bit more clear in future.

Cheers!
