The TR-21 comes with long (1.25 inch) black flathead screws (4-40).
These screws are the countersink type and do not work well with my
fiberglass instrument panel. They have a small head.

I'm looking for a source for machine screws, 4-40 x 1.25", in a black
non-metallic material. Any suggestions would be appreciated.

"non-metallic material" or non-magnetic? Most mounting hardware is
brass or nylon (very low strength)and the heads are painted with black
prior to installation.
