Mystery Flathead Screw
(OP)
I would appreciate it if someone could give me the technical term for this flathead screw. http://www .vegasamus ement.com/ eng/Myster y_Flathead _Screw.jpg 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.

You use to find these everywhere when it was fashionable to build you own box. All the component suppliers had little bags of them, in fact I'm looking at a half bag of them a the present time. Unfortunately it has no label.
How many are you looking for?
I would check.

He has seen fasteners with your approximate dimensions but they had thread forming threads.
The bevel at 120 degrees is unusual in respect that the normal bevels are 82, 90, and 100 degrees. The 120 degree bevel is common on flush rivets for thin skin applications.
We tried to use the backdoor approach by contacting manufacturers of 120 degree countersinks. No luck, they professed no idea of the end use and didn't part with any names of purchasers.
A local box builder, no longer builds, couldn't tell him any of their suppliers even though they were sure they used this size. They were no old hands around.
His suppliers only offered the 82, 90, and 100 degree head as standard. Both had a a quantity 1000 for non-stock items. This might be of help if you find someone who makes them.
Don't give up, strange things have happened on the way to the Forum.

also fits. This would be equivalent to a
M4.165 x .706mm pitch. Very close to the
M4 x .7mm pitch.

Make sure you check the links. Enough for now.

There will probably be a minimum order of 25,000 pieces or so for a total custom screw, with any features you want.
You will be amazed how small a container that quantity will need.
You will probably be pleasantly surprised at the cost.

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

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 .
