Again, I beg to differ. The issue under discussion was the use of
thread locker in installing replacement studs, after the broken stud had
been removed. The representation was made that loctite would prohibit
subsequent disassembly. It will not. further, the purpose of using a
stud rather than a bolt that would be removed fron the casting from time
to time is that the threads in the casting are not suitable for multiple
dissassemblies. I have yet to see a fastener secured by loctite that is
sufficiently corroded to shear, not even close. A stud in a casting is
properly installed by threading it in little more than finger tight,
secured with loctite. Lets not malign fine products if we don't
understand their application. John
