Surfaces should be dry, clean, and free of any contamination. Thread locker should be applied to the bolt in sufficient quantity to fill threads. ChemTools 8243 performs the best in thin bond gaps. This thread locker is specifically formulated to give controlled friction and torque/tension ratio during assembly.

Storage:
Anaerobic adhesives shall be ideally stored in a cool, dry place in unopened containers at a room temperature between 46 ºF to 82 ºF. Please do not return any unused material to its original container.
