I'm fixing up the iron work on some old chapel doors and I'm looking for coach screws with an antique appearance - ideally square head rather than hex - and blackened or unplated. Anyone suggest a source?
Prob need around 50, daimeter not critical M5 orM6 or whatever that is in old money 3/16"-1/4", around 25mm / 1" long - but again not critical.
Is that wise? Are you fastening hinges?
They're fairly widely available try googling 'square head coach screws'. You can 'antique' them by heating in a fire and leaving them to rust a bit.

periodproperty.co.uk sell medieval style screws, though not cheap. Its worth noting that such things are used way out of character more often than not.

Thanks for the tips - no, the coach screws aren't being used to hang the doors, just the decorative hinges (original) and door hardware.

Any acid works - even vinegar. If you're going to blacken them, it just needs to be roughened.
Liberon do a good black wax for steelwork. Not weatherproof though.
If I'm doing black iron for rough / outdoor use, I heat it with a blowtorch and wipe it with used sump oil. I'd also leave the zinc on in this case.
