Threaded inserts for plastic
I have just been converting my quantum to run a polo radiator and it is all now together. I have had it on and off so many times that the m6 threads I
tapped into the bosses on the polo rad to mount it are beginning to feel a bit "soft" when I do them up now.
Anyone ever used anything like this before?
http://www.theinsertcompany.com/brass_vaned_expansion_inserts_for_plastic.phpIt
would give me a metal-metal thread that would tolerate being undone fairly regularly and secure what is there.

They're regularly used in plastic boxes for exactly this purpose. Only problem with them really is buying them in small enough quantities. RS
sell them in bags of 100.

I thought self tappers were even less tolerant of being reused, almost to the point of being 'single use'?

Self tapers are ok if you reinsert the screw/bolt carefully so that you reuse the first tapped thread every time. (ie wind the screw backwards till it
clicks in to the thread).

I had a similar problem with my polo rad, so I araldited some threaded bar into the holes, and used nylocks and washers on the other end
its been like that for a few years now

Thats was probably spelt wrong, or had some grammer, that the "grammer police have to have a moan at

JB weld into the hole, screw in the fixing with a single wrap of cling-film around it, leave to cure then tighten later - simples.

You can get something that looks like a nutsert but has a rubber body so you get a bit of damping too. Not sure where from though
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

I actually have studs in there at the moment anyway so the plan for now is to try a set of inserts that are "press in" that I bought from
flebay today. If they don't work as the manufacturer intended then I will do as suggested above and below and bond it all in with epoxy.

Simon, I would recommended you checkout http://www.fasteningsolutionsuk.com/ also, they are a decent supplier of inserts.
I have used them for a while now, they offer good shipping also for bulk orders.
