Pro Seal Blue Thread Locker, 50ML

The SUPG24250 Pro Seal Blue Thread Locker (50 ml) is a removable-strength blue anaerobic threadlocker designed to keep fasteners from vibrating loose while still letting you take things apart later—using hand tools, not a torch and a prayer. Built for fasteners up to 3/4 in diameter, it also helps seal threads, prevent galling and corrosion, and holds up against common shop fluids like gasoline, antifreeze, transmission fluid, and oil, with a working temperature range from -65°F to 300°F.
