Slab base weld nuts?

[marknotgeorge]

I finally got the last nut of the bumper off on my TR7, using a nut splitter and various metal twatting tools. Now I have a problem.

The rear bumper on a TR7 is held on with 6 M10 nuts, which screw onto threaded studs. These studs go through the bumper frame to a plate, which presumably had weldnuts or something on to hold the other end of the stud.

I say had, because 30 years of corrosion has meant that all but four of the studs have come out, having frozen to the nuts. Replacing the studs would be fine, but in two or three of them, the bumper-side thread has come away and is rattling round in the bumper cavity. I can't get in there as it's all welded up.

I figured using some of these might help:

They're slab base weld nuts. I can weld these to the bumper frame, put the stub in them and be done.

But where do I get them? Any ideas?

I'm sure I seen one of these the other day on a website..

Hope this helps you out, BRB with the link.

on the page, far right about eye level.. Is that the kind of weld nut your looking for? I've downloaded the image too just so you can have a look before looking on the site.

Just be careful of quality, most are stamped out, and the threads are very poor. You could make the same but better with a piece of plate with a hole in middle and nut welded on the back.

you could use m10 back plate which are available in black/galv iron,you can get them from most plumbing/pipe stockist like plumb centre/pipe centre/bss/plumbase/city plumbing.

Would channel nuts do? You can get them from fastener suppliers & electrical conduit stockists.

sorrey for duplicating your idea shox i never noticed

 

[Shox Dr]

No prob's Great minds think alike

'Volksbolts' will sell them, they are the weld in fixings we use to replace the nuts that are used to fix the wings on a Beetle. I have a tub with around 20 in in my workshop

****edit****

sorry, volksbolts no longer sell them, 'megabug' have them though

Beetle wing captive nuts

VW Heritage do them too but are asking £2.50 each

(To shox and brightspark, the ones I have are very good quality indeed, they are forged rather than pressed and it is very difficult to strip the threads in them)

The beetle ones will be M8 though, not M10.

The beetle ones would be just the thing if they were the right size. I can't weld nuts onto plate, as I wouldn't be able to fit the nut through the hole in the bumper. I've found a supplier that hopefully won't make me buy a shedful.

Wow, thank you for that link, loads of very useful bits and bobs available on there

 

[Ratty]

Great link cheers Hitch - can you get it added into the linky thread?

Mark..if nut's won't fit through how about welding on a nutsert? There's a few different types to chose from here and you can buy in small quantities
