As I remembered and checked, I don't see any T41 green locker used in Trex-manual, at least not from those I built. Can you tell where T41 threadlocker apply, is for screws and nut fasteners or for bearing mount.

As I know T41 is SAF-T-LOK product and is medium strength, used for bearing mount, i.e. retaining compund. On the other hand, Z42 is zap product, medium strength and used for screw/nuts fasteners.

If you find T41 is true, then Z42 is not substitute for T41.

can u tell what trex model and if you may find from manual where T41 applied. Trex manual pretty good and indicate where you should apply thread locker, CA or adhesive.

my trex kit manual use T43, R48 and CA, no T41

I suggest you do not use T22, it is low strength threadlocker and I won't use for any metal to metal fastebers in heli. use your Z42 instead which is medium stregth threadlocker.

I suggest do not use Z42 to substitute R48. R48 is reatining compound and used for bearing mount or other press fit/slip fit application. Retaining compound can be used as threadlocker but not vice versa. All retaining compound are designed to withstand dynamic radial load, like on bearings.

I would go to lhs or hardware store to pick up R48 or same loctite 680 or 609. I used loctite 242, 243, 680 and 609 all the times, depends on the applications.

R48 commerical name is loctite retaining compound and medium strength, loctite 609. Loctite 243 and 242 are both medium strength threadlocker but 243 is capable of being used in oil contamination, like thread /w grease or lubrication

I ordered loctite 609, 243, 242 ... from grainger.com

I have attached loctite reference chart too.
