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. 
That's ridiculous the dealer won't help.... I would never step foot in his store again
he didn't buy from that dealer, that's why they are going out of business now if they waste their time dealing with people that go and buy elsewhere.
