I realize that blue Loctite is our friend and would NEVER consider not using it on things like bit adapter screws..... but is it really necessary on the threads of the QC when you are changing it out?? It seems to me that the direction of rotation keeps the QC tightening in the right direction. Not using Loctite on those internal QC threads would make it easier to remove the chuck to really clean it well, or to change it out again, if need be.
Just wondering.......
