Silver Case

I need to pin my headset plug today. I just went through my set screw collection. I have some nice 3mm X 6mm set screws that would work great. And I have a nice 3mm tap.

That would work, except the set screw is a 0.5mm pitch ISO threading system and my 3mm tap is a 48 threads/inch American Standard Unified thread system. Those two aren’t going to cooperate. I double-checked all this with my Machinery’s Handbook 28 to confirm.

Damn it. Basically my taps are useless. I’ll have to buy the appropriate tap when I buy my chuck key.
