Emax MT2204 nut caps?!?

[thelakes]

I'm having trouble finding the right size nut caps for my Emax MT2204 motors I've ordered a few different ones now from different suppliers and each time there too big. They don't screw on they just slid on so obviously the wrong thread size in the nut.
I have got over this by adding PTFE tape to the thread on the motor to bulk it out but still have to re-tighten ever flight and i know this isn't the safest thing to do.
Can anyone help have i just been unlucky on three orders from different websites or has anyone else ever had this problem?

You don't need those, just go to your local hardware store and get some standard M4 nyloc nuts. They won't come off.

M5 is pretty much the standard.

yer after i wrote my last comment i did check emax website and its definitely M5 so would be easier to find reverse threaded locking nuts but cant understand why the 3 sets ive bought are all too big
