Fixed a Wickes rad to a wall for a customer yesterday.

Rule One of fixing things to walls - throw away screws & fixings
supplied & use your own.

But these looked a bit good. Huge meaty plugs & coach screws.

I broke Rule One & tried to use them.

No size marked on plug as usual. Read instructions; "Using a 9mm
masonry bit, drill holes for the plugs".

9mm???

Check extensive stock of drill bits. 8mm & 10mm - no 9mm. Check in
Wickes book. No 9mm. Check in SF, TS, ITS catalogues - no 9mm.

Tried 8mm, plug wouldn't go in, tried 10mm, plug spun.

Applied Rule One & binned the bloody things.

Why would anyone make a plug that doesn't use a standard size hole?

There's a 9mm in my collection -no idea how long I've had it, perhaps it
was to fit radiators ;-)

plenty on google.
