Philips heads

I am STUNNED that no-one except me knows that Philips heads are all but
obsolete these days.

You MUST use the correct driver.

Plenty still use the term for any cross head screw.

I'm pretty certain Mr Cook knows there is more than one type...

Come to replace them and they are not in fact 3mm , bit larger than 2.5mm ,
they would seem to be 3 UNF threads on 1978 Japanese Aiwa AD9700. Well 3 UNF
threaded screws have gone back in there comfortably and securely, manual
just specifies some company stock number. Whatever they were , for the size
of crosshead (saves argument), they were well glued in .

On equipment of that era it was common to indicate metric thread screws with an
embossed dimple on the head.
