Where can I find 12-24 screws for my 27 coupe dash?
Trying to put together my 27 coupe and looks like all my dash screws and swing arm bracket screws are all 12-24. Mine was a Canadian car and had Robertson oval head 12-24 screws, but they are in rough shape and some broke trying to remove. I bought the interior trim screw package from Snyder’s but it didn’t have any of the right size. Anyone know where to get some? Doesn’t have to be Robertson.

Google finds plenty of 12-24 machine screws, but with combination heads. Have you tried Lang's?
The inevitable often happens.

Be careful when searching online, many of the screws you find will be stainless steel. I am not a fan of stainless steel fasteners, they tend to gall if not liberally coated with anti-seize.
Try searching for "12-24 square drive screws", that may give more results than searching for Robertson head.

Stainless slotted is about the best you're going to find short of making the screw yourself

Mark's comment on galling is valid but from my experience, only with larger fasteners...12-24 is a coarse thread and the torque/forces applied are generally too small to move material around. The key to installing them without damage is to use a gunsmith's screwdriver with parallel-ground tips so that you do not burr the slot.
If you want Robertson heads, you're going to have to make the screw yourself and blank the heads square. If the car was a Duesenberg, I'd do it...but it's a "T", so I wouldn't.

Thanks everyone, thought maybe I was missing something the suppliers carried or might have found locally but guess I’ll just order the stainless slotted ones online.

Just about all those screws were also used in the Early Model A Fords.
If I had lots of time, I would make a cross reference of all the 1926-1927 parts used on the Model A Fords.
One is the little handle that turns off the gas to the carb is no longer available, but the handle used on the early Model As can be used, if you cut off the finger on top that limits the turn and round off the area.
