threaded studs - help

[r1ot]

When I was an apprentice we used to use these threaded studs which had a base with a knurl on it which was fitted into a hole in aluminuim and then secured using a punch with a hole in it passed over the thread. This was then hamnmered down cutting the base into the aluminium leaving a threaded portion on the otherside and on the reverse side the base was flush with the aluminuim.

I hope my description was clear?! I can't remember what the trade name was for these things and I need about 20 of them in M4 x 10. Does anybody know any suppliers of them.

Thanks

Have you checked your local fastener suppliers? See Yellow Pages under 'Fixings and Fastenings'.

You can get countersunk rivnuts if you need them to be flush.

That sounds like a Hank Bush to me.
