Mystery Flathead Screw

[GamEng]

I would appreciate it if someone could give me the technical term for this flathead screw.

I have searched high and low for this fastener with no success. The screw I measured was one that I found on a computer case. I am in need of them for my current project I am working on, thanks in advance.

One last item: should help with the angles/calcs./specs. and terms.

OK, this has been bugging me! It's not the undercut that I thought it was and the closest I can find is a slotted flat trim head screw at:

Another site makes reference to an "M33" specification (vs the DIN 963 for example):

lumenharold ,

You are right that is the closest I have seen, if it only had a phillips head instead of the slotted head I would kiss you, lucky for me and you it isnt the exact screw. Tempted to try them but the old fashion slotted head proves to be worthless in many application. Thanks lumenharold .

This screw reminds me of the stang attach fasteners on Grumman manufactured thrust reversers, such as those used on the AMD-BA Falcon 10, or the IAI 1124 Westwind Corporate jet aircraft. I don't have the p/n in front of me, but I'll check tommorrow. Betcha they're too expensive for your application, tho.
