Super Glue 6 ml Blue Removable Thread Locker (12-Pack)

Blue removable thread locker is a liquid that completely fills the inner space in threaded metal parts to prevent loosening. More effective than lock washers or nylon inserts which work only in a limited area as they push against the face of a nut or screw head. Assures positive, controlled locking; prevents air, oil and water leakage; seals out corrosion, but allows easy disassembly with hand tools even after extended exposure to weather.
