Gosh they do look great, excellent color and text. 
My own fault for not seeing that these were metric I suppose. But Vintage Strat = metric does not compute in my mind and simply adding to cart does not get you to the installation information. Perhaps metric should be indicated right there on the Vintage Strat page?
You squeeze a CTS pot like that (first thing I thought of doing and did) and it will likely break. That has been my experience anyways. Better to gently ream out the hole in knob until you get a snug fit.
