I bought about 10 nylon set screws from CCI a couple weeks ago. They're pretty cheap and hardly ever wear out if used properly.
I guess the difference is that I've had my TPC in the same spot for a while now. I chrono'd at 270 and counted the turns on my TPC so that everytime I take apart my gun I just reset it to the same spot before putting it back together and tightening the set screw. I re-chrono everytime I go out and it's always the same velocity so I haven't had to adjust it since then, plus 270 keeps me safe all day as things heat up. If I had to change it, the set screw will hold it steady, it's just a little hard to move and moving it with the set screw locked down will wear it out faster. Though at 15 cents a pop I'm not that concerned and like you I've got about 10 of em' sitting around just in case
