They always stay tight. Never in all this time with all the hundreds of screws I have installed had one back out that was properly tightened. So now that I think about it, I have only had to chase the threads in a maybe 3, 4 nutplates, ever. Maybe they were out of tolerance too small. And I may have had to drill out/twist out 1, maybe 2 screws ever. Not a frequent problem. Moving ahead, I think using ACF-50 (ref Mickey's comment below) or some similar product would be the first, best course of action if you have a tight fastener.

I find that Torx (6lobe) are so much better than Phillips head screws. If you put the tool in, and of course use the right size, it does not come out. Can't say the same with Phillips.

I have not had any issue with galling or seizing, but I always touch mine with a tiny bit of ACF-50 before screwing them in the first time. It lasts a while.

I now use JIS screwdrivers on all of my Phillips screws. Much better "grip" than with Phillips screwdrivers. They are a virtual necessity if you actually have JIS head screws - like in Denso style alternators (ask me how I know ).

Another vote for the Torx and also echo the thinking of if you're stripping them, something other than the screw is the issue. I've used Torx in decking applications and a single Torx bit will last an entire 10 lbs box of screws and none of them strip out, this is a high Torx, high speed use case.

Default When using the inferior philips, use a superior tool.

I agree that TORX is a superior engagement for screws, but only if the screw material is equal. They are not for our aviation application as mentioned by Walt and David Paul. Yes, A286 is good if you can find them in a 6-32. Our exhaust system nuts are A286.

Read somewhere that Phillips screws were designed so that you couldn't over-tighten them, instead the screwdriver would pop out.

Don't know if that's true or not.

I always have a supply of spares, and any screw head that looks even slightly worn gets pitched. Ten cent screw vs ten minutes of trying to get it out?

Torx actually DO come in 100 head!

To prevent galling of the SS screws use Boelube on the thread, it always worked for me.

Micro has a pretty good supply but only 1/2" long in 6-32.

They only seem to have the 82 degree flat heads and they cost $8.90/ea? Maybe this is for 100 pieces? Couldn't find that in the description, though.

I may stick with JIS screwdrivers and Phillips
