Thread size is 5/16-24 fine thread (NF National Fine)
Rick, They are longer than necessary to secure the doors. The additional length allows the ends that protrude beyond the plate to rust and then they are very difficult to remove.
I'd say 5/8" of threads with total length of 3/4" is more than enough to adequately secure the doors.
I just went out to the garage and found one..... will send you some PIC's via my phone
Here are the PIC's of the Door/Hinge screws.
1st PIC shows the screw and a guage I use to identify for thread and size purposes.
The head is round with angled shoulders and the threads are 5/8" in length. It has what I refer to as a Phillips head.
2nd PIC I placed the screw head in the "slot" of the guage to show the taper.
3rd PIC depicts the screw in the 5/16" hole. The threads are 24tpi fine as Gary T stated.
Interesting comment, with useful info about rusting. But I think the extra length is to help install the screws. It's difficult to get the hinge plate lined up and flat enough against the surface to get the screw in. Maybe use a long screw for just the first one in each hinge plate and then replace it with the shorter length after the other screws are inRick, They are longer than necessary to secure the doors.

You are correct Jack.... I forgot to mention a good source.Available from Sunbeam Specialties
10 years ago I made a pair of these from old screw drivers. One phillips and one flat blade. I should have got a patent. LOLOne thing that helps greatly with screw removal is the "Screw Buster" from Eastwood. Attaches to an air hammer, and cost is only 20 bucks. Makes removal of even rusted screws possible. Wish I'd known about it sooner. David
