After removing and putting my SS7 Cowl back on, I can't find one of the fasteners. It is a phillips head fastener that sits flush when turned 1/4 turn. It has an "S" and a "2" on the screw head. I've been told it is a Southco fastener but after searching Aircraft Spruce, I can't find a Southco fastener that looks like mine. Anybody know what I have and where to get more?

I've tried to attach jpg files 10K in size but I can't figure out how to do this. Following the instructions on "Inserting pictures into your message" thread did not work for me. This has to be fairly easy thing to do because there are many pics often posted on this forum. Thanks for any help provided!
