What is a CR-VPH2 screwdriver bit
I'm working on the repair guide for the 24" A1225 iMac. The captive screw on the RAM access door is a Phillips screw, but strange one. It's shallow and a standard phillips does not work well. I found the correct bit in my security bit set. It's a CR-VPH2. I can't find a wiki that explains just what this is or the initials stand for and don't want to put something in a guide that I am uncertain of. I believe the last part stands for Phillips Head #2 but I don't know what the rest is for. Anybody know?
