Loctite 243 Medium Strength Threadlocker 50ml

LOCTITE® 243 is a blue, medium-strength, oil-tolerant threadlocker designed to lock and seal metal nuts and bolts to prevent loosening from shock and vibration.

Key Features and Benefits

• Medium Strength: Secures fasteners firmly while still allowing disassembly using standard hand tools. 

• Oil Tolerant: Cures reliably even with minor contamination from industrial, cutting, or motor oils. 

• All Metals: Works on active metals and passive substrates like stainless steel, aluminum, and plated surfaces without a primer. 

• Vibration Resistant: Prevents loosening on high-vibration machinery such as gearboxes, pumps, and presses.
