Beeswax is also very good to use when tapping aluminum.

EZ-Outs for when the above fails. If you don;t chase a tap through your #6's, I believe it's only a matter of time under the best of conditions...
A mole of screws??? What's the atomic weight of a screw?

This helpful hint first published in The Experimenter by Avogadro

He considered it to be the normal solution.

Wink Ribbed for your pleasure

I always make sure I have ribs on my tip when screwing. I do not use lube, I just put them in there. No sweet-talk or anything like that, just go for it.

The lil ribs on the tips hold the screw tightly. This also helps in tight quarters and unusual positions if the driver is a little out of alignment with the screw. As for the shaft, the threads do get roughed up by the nutplate, but I figure that is how it is supposed to be?

If you think it's an issue of dirt, paint, or other FOD, I cut a slit length wise in the threades with a dremmel. The slot cleanes out any materials without cutting new threads or making the "hole sloppy" just use the screw as a chase and then replace it with a new fresh screw.

+1 But lube allows return performance, less trauma.

I seldom (almost never) have a driver slip now with the ribbed, replaceable tips.

Default Tap

Boelube for sure but I actually run a tap in three turns. It leaves plenty of tension. Downside is the time involved. When I have a few extra minutes but don't want to start a new step, I tap nutplates.

Doing the same for #6 screws.
These strip even more than the phillips. Ask me how I know. I did both wing tips with these and i get a few stripping every time I remove the tips. I've been switching back to Phillips as these strip.

1) Torx might seem like they strip easy, but are you sure you are using the correct sized bit? Because they work for a while with the wrong bit, and then strip. Also, people often mix Torx and Allen tip heads all the time. Again, they mostly work but will strip eventually.

FYI, Phillips head screws are designed to strip. They were first created so machines could drive screws, and have the head strip before the threads did.


2) For sure tap the nut plates. I think they are using the same tap to make them, that they used 50 years ago, and it is getting small.

3) Boelube also helps a lot.
