...I appreciate that but if that design needs loctite
they should include it in the package...
Using your logic, every electric bass should include an amp.
Nothing wrong with being not so well versed in the proper use of tools, but to blame that on a manufacturer because you don't know how to use their product is pretty weak.
I've never had to use anything extra on my schaller strap buttons and I've never had one come loose unless I took it off, but I know which tools to use and how to use them to insure they will not come loose, so it's not a matter of a poor design or something not being included in the package, it's a matter of knowing how to properly use what you do get in the package that matters.
I have no idea what they are actually supposed to be used for! But I've been using them for about 3 or 4 years on all my basses.
