Hello,

I am looking for something but do not know what it is called. It is a
clip that you attach to one sheet of metal and then screw into a hole
in that clip, through another sheet of metal, holding the two pieces
of metal together.

Googling has found me some of what I am looking for:

Looking on the internet, Halfords call them u-clips:

ebay calls them spire clips:

What is the proper or most common name for these, as I am hoping that
knowing that will help me find more sellers, so that I can track down
a good quality item at a good price from somewhere near me or
somewhere with cheap delivery.

Thanks,
Stephen
