Cool, thanks for the pointers. The standards numbers don't seem to help
find suppliers when fed into Google - but I've emailed a company in the
UK who make such screws to see what they suggest. Their MOQ was 5,000
though.. and I only want 25 (plus 10x of several other sizes).

What is the catch with these screws.. I'd have thought they would be
much more common - given how convenient it is _not_ dropping your lock
washers into a piece of machinery when assembling things....
