The "Blue" in PERMATEX 242 signifies its versatile medium strength, which is the key to its widespread use in marine applications. This formulation provides a powerful, reliable lock that withstands the rigorous conditions at sea, yet it is not permanent. When it´s time for routine maintenance, inspection, or repair, fasteners secured with Permatex 242 can be easily disassembled using standard hand tools, without the need for excessive force or damaging heat application. This makes it the perfect choice for components that require periodic servicing.

Ideal for fasteners ranging from 1/4" to 3/4" (6mm to 20mm), this threadlocker is your go-to solution for a vast array of applications on any boat. Use it to secure engine mounting bolts, water pump and thermostat housing bolts, oil pan bolts, drive shaft and propeller hardware, trim tab fasteners, and console instrumentation screws. By applying a small amount to the threads before assembly, you create a secure unit that resists loosening and seals against leakage, safeguarding your investment from the harsh elements.
