Those won't work on V'steen barrier strips. Those are for binding posts with 1/4"- or 5/16"-diameter central sections. V'steen speakers need ring terminals or spade lugs for #10 screws, as barely seen here under the screwheads. These are AQ's direct-silver-over-copper spades.

I have a bunch of them, and I'll sell you 8 for a relative pittance, but I can't find them tonite. If you're interested in pursuing these, e-mail me at jeffreybehr(at)cox(dot)net, include something like 'AQ spades for V'steen speakers' in the subject line, and I'll then know what I have.
