Self tapping fixings

What are the "things" that are pushed on to the edge of sheet steel so that self tapping screws can be used in oversize holes. My old moggie 1000 had them for securing the door panels. Can't find them anywhere but presumably they are findable with the right word!


This kind of thing?

Also consider if you have two thin sheets of steel to join there are self drilling, self tapping screws.

You need to clamp the sheets together whilst fitting at least the first screw and an impact driver comes in handy.

Got an assortment of spire u clips off ebay. Thanks for the help.

We used to use them on the old metal TV chassis to secure the back. They were called cleat nuts by the company who supplied them. A word of warning, they are not good if you lose one on the floor and walk about in bare feet. Brian

Good question, I have been meaning to ask this here for ages!

I have some old kit which uses these to hold together metal screening plates. Was looking to get some replacements as I seem to have lost a few...

Thanks, J^n

Not nearly as bad as a 13amp plug :-(

'Clinching nuts' or 'self-clinching nuts' are inserts to take screws in thin panels. They're often threaded though, rather than self-tapping - a bit like threaded rivets. Although I could imagine a car factory using softer ones with self tappers to save 0.1 seconds on the assembly line.

Spire nuts are sharper than 13 A plugs

The stuff that is normally used are not those - they cost almost a shilling instead of half a pence..

They are normally known as spire clips but I am not sure that is in fact technically correct

Speed clips seems in wide use

But 13amp plugs, pins up, can be an awful lot more painful.

This sort of thing?
