LOCTITE - 638 is a permanent thread lock adhesive. It is designed to hold nuts on permanently but can also be used on the tapered part of the crank/hub to help hold it on. Although this is classed as permanent the bond can easily be broken by the application of a little heat, this destroys the bond. Please note that this will not hold on cranks/hubs that have been damaged through riding when they are loose. The only solution there is to replace the worn parts. One supplied.
