Designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools.

The product cures when confined in the absence of air between close fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration.

Loctite® Threadlocker Blue 242 is particularly suited for applications on less active substrates such as stainless steel and plated surfaces, where disassembly is required for servicing.

Typical Applications: Valve cover bolts, water pump bolts, oil pan bolts, drive shaft bolts, rocker arm adjustment nuts, carburetor studs

Recommended for use on metal fasteners 1/4' (6 mm) to 3/4' (19 mm) in diameter such as bolts on small engines

Removable grade threadlocker. For fasteners up to 3/4" in diameter. Prevents vibration loosening and protects threads from rust and corrosion
