Rivnut tool?

Anyone know anywhere I can buy or borrow a rivnut setting tool?

I've spent all day trying to fit the access ladder to the rear door and have
ruined 6 rivnuts (all I have) using the non-standard technique (loose
bolt/washer/flat metal strip and tighten until it crushes). All 6 rivnuts
crushed beautifully, but each time the expanding bit was too close to the
rim at the top and they squeezed out of the hole rather than lock themselves
in. I'm sure my technique isn't perfect, but I need to do a good job, so
I'm now on the lookout for the "proper" tool. Instead of the "proper tool"
who has mangled it so far :)

Willing to pay hire charge if anyone has one they would care to lend...

Go to google and search for "rivnut setting UK", I spotted a few while
I was looking for brake liner riveting gear. Pretty much the first
link I clicked had the tool for a little under £50.

If that's not quite what you want, there are lots of others to try.

have you tried the tool trader in Merlins Bridge? They're pretty good
for stuff like that. What are you trying to do again?

I'll have a phone around and see if anyone's got one

I'm a lttle hesitant to comment on this without knowing which version of
Rivnut we're talking about and/or whether we're talking the generic sort
of thing or the genuine.

Two thoughts:

If the 'Rivnut' is the type with a very small flange that is designed to
be almost flush with the surface, they are very sensitive to the hole
size into which they are being installed. It's very difficult to achieve
a decent result unless the Rivnut just fits the hole before you start.
If the hole is oversize even the proper tool won't help.

I'm struggling the visualise your description. If the collapsed 'Rivnut'
falls into the hole my first suggestion is the likely issue. If,
however, the expanded bit falls outside the hole it's likely that the
components were not fully in contact before you started the
installation. All the parts outside the hole must be fully in contact
with each other throughout the installation process if it's to work
properly - especially if the hole is oversize. The proper tool will help
you to maintain this contact.

Its the usual factory fastening used on the mudflaps on the RRC and Disco if
you want to get a quick peek.On replacement most folk use a round or panhead
head bolt and lock nut which at first glance appear similar but are more
easily removed.

Pembrokeshire, West Wales. The nuts I'm using are M8 - will yours do this
size?

Yeah, had a good Google about it, and found that site. Problem is, the
cheaper tools (~£50) only seem to handle up to M4 or M6, and the ones that
can go up to M8 and beyond are £90-£120 before the dreaded VAT & carriage.
The sites that come up on Google seem to be specialist fastener companies.
None of the usual LR suspects, which surprises me, given the common use of
rivnuts on Landies.

These were M8 rivnuts from Richard Beamends, Defender heater box for the use
of.

I drilled the holes so that I had to tap the rivnuts in with a light hammer.

I thought they were, but obviously not. Given the torque you need to apply
to crush the rivnut, it's pretty hard to keep things lined up and in
contact, I suppose. The tools I used were the same as those supplied by LR
as a fitting kit with the ladder when I fitted it to the last Disco
(basically a metal bar with an 'ole in it).

Except that the mudflap fastenings aren't blind like the door panel of a
Disco, which is the reason for using rivnuts in the first place.

When I fitted the ladder to the previous Disco, I managed to fix the rivnuts
in the door top but totally failed with those below the no. plate light. I
did indeed fit through bolts and locknuts there, but taking off the inner
door panel and getting the locknuts on the bolts from behind needed three
hands and fingers like Spiderman. I ended up soldering one nut to a length
of wire to get it into the right position behind the door lock. That
wouldn't be possible in the top of the door frame, of course. That's why I
was hoping to use the proper rivnuts, but do it right this time. :)

Hi Rich,

I've found someone that's got one that you can have on an overnight
loan, give me a shout if you want it

So Richard needs a bigger tool to crush his nuts ?

And he needs nuts he can screw with.

Oh the possibilities.

....because the hole his nuts fit into is the wrong size and the shoulder

On the subject of Rivnuts etc, for those within easy reach of Todmorden
(on the Yorkshire/Lancashire border) the firm of Harmsworth, Townley &
Co Ltd have some offers on at the moment for setting tools and so on.
Apparently they are moving to smaller premises, and a lot of stuff is
up for sale. There are special offers until the end of this month.

>From what I understand from a phone chat with the present owner (who
recently inherited the company from her father?), the old place is a
wonderful rabbit warren of un-thrown-away bits and pieces, and a real
Alladin's cave. But they are modern enough to have a website
(www.townleyltd.co.uk). +44 (0)1706 814931.

I think my sister may have married her -- not, that's not what it
seems... as Superintendant Registrar for Todmorden until a couple of
years ago, my sister performed many marriages in the town, and the
wedding of the lady in question fell into the right timescale.

The trouble is that specialist tools factors don't offer a
decent margin, so I/we'd have to charge more than their asking
price, and hence no sales.
If anyone knows a pervayor of such tools who does do a decent
trade discount without having to buy a loory load at a time
I'd love to know.
