I need to replace some missing screw-posts on the face plate of an EVGA GTX 770 FTW graphic card. The ones that hold the face plate to the card and allow VGA/DVI connectors' thumbscrews to screw in. Am I using the correct term... screw-posts? And, are they universal or sold by metric thread size/length? Kinda in the dark on these tiny parts. Not even sure what to search for.
