Loctite® 274 is a medium-strength, low-viscosity threadlocker designed for the locking and sealing of threaded fasteners. It cures anaerobically between close-fitting metal surfaces, providing resistance to vibration, shock, and thermal cycling. The adhesive allows for disassembly with standard hand tools.
Loctite® 274 is a one-component, anaerobic adhesive formulated for the locking and sealing of threaded fasteners that require normal disassembly with standard hand tools. Its low viscosity ensures easy application and penetration into tight-fitting threads. The product cures in the absence of air between close-fitting metal surfaces, forming a durable bond that resists loosening due to vibration and thermal expansion. Loctite® 274 is particularly effective on less active substrates such as stainless steel and plated surfaces, and it can cure through light coatings of industrial oils and cutting fluids without the need for prior cleaning. The adhesive exhibits temperature resistance up to 150°C, ensuring long-term reliability in demanding environments.
