LOCTITE® 266

Known as Loctite 266 High Temperature, High Strength Threadlocker

Features and Benefits

High strength, thixotropic liquid threadlocker with a temperature resistance up to 232°C (450°F). Locks fasteners up to 19 mm (3/4") in diameter.
When a high strength, high-temperature resistant threadlocker is required, consider LOCTITE® 266. It is high strength and cures rapidly on fasteners lightly coated with rust prevention oils, and locks fasteners up to 19 mm (3/4") in diameter. Once cured, it prevents fastener loosening caused by severe shock and vibration, and resists temperatures up to 232°C (450°F). Ideal for heavy duty applications, e.g. bolts used in transmissions, construction equipment or railroad assemblies.
