6750 Connection incompatible with Speaker Stands

[swb162]

I bought the 6750 system yesterday (sounds great by the way), but I am trying to attach the surround sound speakers into my speaker stands; however, the insert screw provided only fit Bose speakers which are smaller. My question is what size insert screws do I need to connect the speakers to my stands? And where can I get them?

Thanks,

Take small speaker with you to lowe's or home depot,they sell the screws
