I cant even begin to tell you, If I was you I would just take one that came with the set to the hardware store or a home depot and see if they have screws that size. These are awesome banana clips.

mine did the same thing I bought 10 gauge wire worked perfectly or you can strip the wire farther and fold it over on its self to make the wire thicker hope this helps you out

NO WAY! An 8 gauge speaker wire will never work or fit in these banana plugs. I had a hard time trying to instal a 5 gauge. To fix them You will need a very small screwdriver to turn a very smal screw that press the wire in a even small entrance. Hope my poor english can be understood. Paulo Vitor.
