iM 4,1-14,4 Where too buy cpu heat sink bracket screws 2009 IMAC

[Radmcg]

I bought a replacement Mother board for the above computer went to refresh the CPU thermal paste and found 3 of the 4 (T9?) screws are missing. Looks like someone was taking it apart and stopped. The only screw left in was the one covered by the warranty sticker. I see a few "sets" of screws on Ebay (most from UK) but none specifically say what screws are included. I need the 4 screws that are on the back of the mother board that screw into the CPU Phillips head screws that secure the heat sink bracket to the motherboard. I think they are T9. If this needs to be posted somewhere else let me know.

Note: I have a loose affiliation with them as I do some system repair from time to time. However, I have no financial incentive to recommend them.

You said these screws are missing from the replacement logic board that you bought.
Can you use the screws from the original logic board? Or, are those missing, too?
(screw size is probably T10)

Take out the only screw left.
Take a picture of it, measure carefully dimension.
Use the picture search function.
After a while, you will find a similar item sold online.

I did the above and finally found a lot of usable screws for my GPU. Some were longer than the original screws, but I didn't mind cutting them off using my power tools.

Normally we bought a box of 500~600 screws of various sizes and pick the one that fit.
