Brand: Loctite Products
The familiar medium-strength (blue) Loctite&tm; 242 Nutlocker is an excellent way to keep critical fasteners from loosening, but many racers struggle with the chemistry. Loctite recommends the use of a special primer on certain "inactive" metals like aluminum, titanium, magnesium and stainless steel, as well as black oxide, cad plating, and zinc plating -- which is pretty much everything racecars are made of! When it isn't convenient to use the primer, this new formula solves the problem!
Loctite 243 is a medium-strength nutlocker which prevents properly-torqued fasteners from loosening due to vibration, yet allows disassembly with hand tools. But unlike the original 242 formula, 243 Primerless will adhere to inactive metals without the need for primer. This is the perfect formula to keep in your trackside kit for emergency repairs when it might not be practical to carry a can of primer. 243 is also more tolerant of minor surface contamination from oil, so a quick cleaning is normally sufficient. Temperature limits -100°F to 350°F (-75°C to 175°C). 6 ml tube.
