I can fix stuff but this cut and paste computer stuff throws me for a loop

using a torque wrench..if that had been done every time the fastener was put in it most likely would still be functional since improper, over tightened or under tightened fasteners will cause premature failure, not an OPINION but FACT.

Used one every time on my inspection cover, and I still have inserts.

I stripped one taking it apart.... not much you can do.. it'll fail eventually.

You would think that a bolt that has a TQ of a little more than hand tight would never strip... must be HD quality.

One thing that can help long term reliability of the steel bolts screwed into soft aluminum threads is to reduce the amount of galvanic corrosion that occurs with the dissimilar metals.  The use of either thread locker coatings or anti-seize coatings can have that beneficial effect.  I wouldn't use a thread locker on the small 1/4-20 stuff, but I do use a light coating of anti-seize.  Haven't had any problems with inspection cover threads since I started doing that, and also haven't had any bolt heads (internal hex or Torx) strip out either.

now i dont feel like the lone ranger...  been doing the same for years jerry and several arguments along with it.. BUT like you, never had one problem since ... I tell ya,,, bring this subject up in the 'wrong' forum and you'll have bone heads trying to tell how much smarter they are...   A few of em linger over here,, but only a very few

This applies to most dissimilar metal interactions. The compounds prevent oxidation of a galvanized bolt, rusting of non-galv and prevents galling of stainless.

I've used LT Red on 1/4x20 bolts, depending on what its for with no adverse effects. (of course that means hand tight going on is NOT going to be hand tight coming off... good stuff) on the smaller bolts use LT Blue.... bolts already in place?... use LT Green.

There is a big difference between thread lockers and anti-seize compounds. Just a little confused about how they are being grouped together on the thread.

You're absolutely correct, they are two totally different products.  Use a thread locker where it's called for, use anti-seize where thread locker isn't required.  Do not use both at the same time.
