Henkel LOCTITE-241 (250-ml-Btl)

Additional Product Information

Overview

Loctite-241 from Henkel is a one-part, low viscosity anaerobic adhesive that cures between close-fitting metal threaded surfaces, preventing fastener loosening and leakage. Formulated for small threads up to M12, it works on steel, brass, and stainless steel. It withstands service temperatures up to +150°C (?302°F) and can cure on lightly oil-contaminated surfaces, making it ideal for aerospace MRO environments where vibration, shock, and thermal cycles challenge fastener reliability.
