Loctite 243 Threadlocker for Automotive: Medium-Strength, Oil Tolerant, High-Temperature, Anaerobic

LOCTITE 243, a general purpose, medium strength, primerless, blue threadlocker with improved oil tolerance, is designed for fasteners between 1/4" to 3/4" (6mm to 20mm). This product can be separated using hand tools. LOCTITE 243 is a medium strength threadlocker that works on all metals, including passive substrates such as stainless steel, aluminum, and plated surfaces. It is proven to be tolerant of minor contamination.

The product is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. It cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It is suitable for applications on less active substrates, such as plated surfaces, where disassembly with hand tools is required for servicing.
