iPhone 4 Thread tapping tool

Hi all,

Does anyone know where to get a tap to put a thread into the mid case?

I had a water damaged phone and the screw that holds the motherboard down, middle-top that is crucial for wi-fi signal rusted and it snapped off.

Was able to drill the screw out but need to tap a new thread.

Any help with thread size or availability would be appreciated.

thanks

Since you are so willing to re-tap your iPhone I allowed myself to find some more info for you. Here is the drill size to re-tap it :

Thread Size Tap Drill (mm)

M1 x 0.25 0.75

M1.1 x 0.25 0.85

M1.2 x 0.25 0.95

M1.4 x 0.3 1.10

M1.6 x 0.35 1.25

M1.8 x 0.35 1.45

M2 x 0.4 1.60

M2.2 x 0.45 1.75

M2.5 x 0.45 2.05

M3.5 x 0.6 2.90

M4 x 0.7 3.30

M4.5 x 0.75 3.70

and here is a site where you can get the tap. As for the screw size, use a pair of caliper and measure the diameter of your screws. If you are not sure how to determine if its metric or standard check this site http://mdmetric.com/tech/tic1e.htm Good Luck and a steady hand to you...

Thanks oldTurkey03 that has been very helpful. I am willing to give it a go. Otherwise I have to buy a new mid case.

Well, good luck to you and just be careful the smaller the thread the tougher it can be....;-)
