What does the loctite 648 retaining compound work for?
Loctite 648 is an anaerobic adhesive, which means that it works in the absence of air. It is ideal for close fitting surfaces that form such a tight bond that they do not allow air in. It is often to form a strong bond between smooth metal surfaces. It can also stand up to heat (up to 200 Fahrenheit degrees,) so it will not lose its strength in a hot environment. In particular, it can be used for holding metal gears onto gearbox shafts and rotors on electric motor shafts. It can be purchased at a variety of retailers, as a quick search reveals: http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Daps&field-keywords=loctite+648&x=0&y=0 Sources: http://www.ellsworth.com/display/productdetail.html?
