Replacement for speaker binding post


This is for my Sonus Faber Toy Tower.

Not sure what's the right term for this thing. But somehow I lost one of the screws on the back...

I bought mine from Audiogon so the local dealer won't help me out.   Anyone know where I can buy a replacement ?

I’m actually shocked that a dealer wouldn’t support a line it sells because you purchased something used online. That’s like a Toyota dealer not servicing my car because I bought it used. 
 Even though with the above links you’ll probably get them for a better price as this dealer sounds like a real tool.
