Title:

CPU fastening screw size and source?

Text:

Hi all,

Performed a CPU upgrade on my 20 inch 2210 iMac from 2.4GHz to 3.06GHz recently, which was cool.

I broke 2 of the screws that fasten the heatsink to the CPU on my iMac. There are 4 spring-loaded phillips screws on the top of the board and four 7.5mm T10 screws on the bottom. The ones I broke are on the bottom. The heads of the screws came clean off! The iMac runs a bit hot as a result.

Can anyone tell me if there are any more specifications for these kinds of screws? I've heard screw sizes being M1.4 and M2.6 and I have no idea what these mean or which one would be right for me.

Also, does anyone know of a good source for buying these kinds of screws online?

Thanks in advance.
