Screw size

So I am trying to put in my Infinity 10.9 T tweeters. I lost the Allen wrench that came with it to loosen the wire screws. It is literally the smallest Allen head ever. I have a 3/64 and it is too small. I have called Infinity but couldn't communicate with the Indian support guy and have Emailed them. Does anyone know this screw size so I can finish my install?

 

whenever I was faced with a problem like you are having, I took said screw to the local hardware store and match the screw head with the correct size allen, it either is metric or SAE, shouldn't take you long, but more than likely you will have to buy the full set of allens to complete your job...

 

I did. Took it to Lowes but their smallest wasn't small enough. Hopefully Infinity customer support can come through

 

Go to your hobby store. Probably 2 or 1.5mm

 

Heard back from Infinity. It is a 1.0 mm wrench.
