Q. How can I remove fasteners held by threadlockers that can't be disassembled with a hand tool?
A. Heat is the key to removing them. Temperatures of 325°F and above are needed to break down a standard (removable, low and high strength) threadlocker. High temperature threadlockers require 500°F and above to remove them. A heat gun or propane torch is commonly used for this purpose. For small screws, hold a hot soldering iron (700°F) on the screw for a few seconds before removal. In each case, care should be taken as the disassembled parts will be very hot.
