Afternoon all,

 

Potentially daft question but can anyone advise if the door mirror nutserts on late model door skins are welded in, or are they just supposed to be a push/interference fit? My doors have been re-skinned at some point, and it's had holes drilled for earlier mirrors 36 mm apart (in the wrong place too - far too far back) so I want to return it to standard at bodywork time so I can fit the mirrors I want. I can work out position from pictures, but is there a template available, to get it spot on?

 

Cheers,

 

Rich.

Pretty sure they are rivnuts.

[rich_959]

Thanks Panky, that makes sense. So they're 'popped' in with a rivet gun?

 

Here's the part...

Yep you need a special tool to fit them but I think you can use a bolt to squash them into place. I've never fitted a rivnut so hopefully someone who has will put you right. If you search for then on Ebay it may give you an idea.

It can be done no problem with a nut and bolt and and a couple of spanners,

if your are ever over in the West of the county you can borrow this from me,

 

 

won't be using it for a while,

Do you need an individual adapter for a particular thread or do they just slide down the bore of the rivnut?

[rich_959]

Excellent info, thanks guys. So whatever the bolt spec of the standard mirror is - you're basically forcing the same thread through the rivnut, which spreads it wide enough to grip the door skin?

 

Next stupid question....... how big a hole do I need to drill?! I'll wait til I get the rivnuts and just measure with calipers

[MacGyver]

It works a bit like a classic rivet, adapter for each thread, screw in and pull out...

Picture is easier...

Great diagram MacGyver, thanks very much.

I drilled mine to accept M6 rivnuts. Trial fit of the mirrors shows a great fit!

Hi,

 

I have just bought some Rivnuts from Mini Spares (ADU2038) but can anyone tell me what thread bolt/screw I need to fit them as my original bolts seem to be the wrong thread?

 

I need these as I am about to fit a new door skin and want to fit the Rivnuts first. 

[Bobbins]

If you're fitting the rivnuts using a bolt and spacers just find a bolt that is a correct fit in the Rivnut, it's likely to be metric. I'd suggest however investing in a proper Rivnut tool, you'll use it plenty more once you have it!

3/16" UNF.

[johnv]

you can get the UNF rivnuts OK but I can't find a source for an insert or even complete tool to put them in .. (unless you spend a fortune getting one from the states)

 

very happy to be proved wrong!

[Steve220]

Problem with going imperial rivnuts is its expensive. As I said above, M6 works just fine and readily available and cheap stainless fasteners can be found.
