Loctite® 270 is a high-strength, low-viscosity threadlocker designed for the permanent locking and sealing of threaded fasteners. It cures anaerobically between close-fitting metal surfaces, providing robust resistance to vibration, shock, and thermal cycling. The adhesive is particularly effective on passive substrates such as stainless steel and plated surfaces, and it fluoresces under UV light for easy inspection.

Loctite® 270 is a one-component, anaerobic adhesive formulated for the permanent locking and sealing of threaded fasteners. 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® 270 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 high-temperature resistance up to 180°C, ensuring long-term reliability in demanding environments.
