What diameter of screw do I need to attach a fender humbucker to its pickup ring as the one in my black top Tele is gubbed.
and the spare GFS ones I have are too thin.

If it's a US or Mexican part the screw will be an imperial size and staff in hardware stores will all look at you as if you're insane if you ask them for one.

Take the pickup to the store with you and try different screws until you find one that fits.

I had a problem finding grub screws for my Supersonic as the guitar shops only stocked US screws and those are Japanese saddles. I finally got a working screw from some block saddles that HR gave me.

Just take the part in and start trying until you find one.

do this. I always use hardware store screws and I just take the piece in and find one that works. It's never failed me before.

I'd need to take to whole guitar as my soldering iron is gubbed...

Then take the whole guitar.

Did someone say Imperial measurements?

Emailed fender and they say 2.5mm, and to try the screw from the other side of the pickup (don't ask me why I didn't think to try it...) turns out the hole in the pickup lug has been wrecked by the misaligned screw during manufacture and theyâ€™re going to replace the pickup under the warranty.

That's interesting, and hopefully a happy ending.

I was just Googling for more information and turned up:

A version of this standard, called SAE for the Society of Automotive Engineers, was used in the American automobile industry. The SAE is still associated with inch based fasteners by the public even though the U.S. auto industry (and other heavy industries relying on SAE) switched to ISO preferred series fasteners back in the 1970s and afterwards.

Screws are described as 4-40, 6-32, 8-32, 10-32, 10-24, etc. (for numeric sizes, odd numbers are rare), or 1/4"-20, 1/4"-28, etc. (for inch unit sizes), with the first number giving shaft diameter (numeric or inches) and the second number being threads per inch.
