Stop in for a cup of coffee

To answer to this one, this must be easy to find in a regular hardware store.

But, it looks like this: Pan head, phillips, 1/4" x 1 1/4" (6.35 mm x 31.75 mm) regular sheet metal screw. Dimensions according to my Czech caliper.

Looks like I struck out on both. Closest I have on cluster are #10 and have a countersink to the head. The armrest screws in pic are from 74- 76 and much larger.
