This is a 10ml bottle of SAB Green "High Strength" Retaining Compound Thread Locker. Green thread lock is generally applied to fasteners that are already assembled and "wicks" down into the threads of fasteners using capillary action. This is simple preventative maintenance to help seal your metal on metal points.

Green thread locking adhesive is not permanent and will not permanently bond the screws. If you are having a hard time removing thread locked screws, use some heat from a heat gun as thread lock will break down under high temperatures.
