Threadlocker 243 High Strength - Henkle Loctite

The Loctite Threadlocker 243 (Model 1330906) is a versatile, medium-strength threadlocking solution engineered for professional automotive and industrial applications. This advanced anaerobic adhesive reliably secures and seals threaded fasteners, preventing loosening caused by shock and vibration, even on "as-received" components with minor oil contamination. It is designed to enhance the integrity and safety of crucial assemblies while allowing for future disassembly with standard hand tools.

Key Features

• Medium Strength Formula: Provides a dependable hold for metal fasteners, ensuring components remain secure yet can be disassembled for maintenance using common hand tools.
• Oil-Tolerant Application: Formulated to cure effectively despite minor surface contamination from industrial oils, such as cutting, lubrication, anti-corrosion, or engine fluids, eliminating the need for extensive pre-cleaning.
• Vibration and Shock Resistance: Prevents the unwanted loosening of threaded assemblies that are subjected to dynamic loads and vibrations.
• Broad Metal Compatibility: Suitable for use on all metals, including active substrates like brass and copper, as well as passive materials such as stainless steel and plated surfaces.
• High-Temperature Performance: Maintains its locking and sealing properties across a wide operating temperature range, typically from -55°C to +180°C (-65°F to 360°F).
• Corrosion Protection: Seals threads to protect against rust and corrosion, extending the lifespan of fasteners and components.

Applications

Loctite Threadlocker 243 is ideal for securing fasteners in a wide array of professional settings where reliable locking and easy disassembly are crucial.

• Automotive Assemblies: Commonly used for securing engine components such as rocker studs, valve cover bolts, oil pans, disc brake calipers, intake manifolds, and alternator brackets.
• Industrial Equipment: Effective for locking bolts on pumps, gearboxes, presses, electric motors, and general industrial machinery, preventing loosening from operational vibrations.
• General Maintenance and Repair: A go-to solution for threaded fasteners between 1/4" and 3/4" (6 mm to 20 mm) in diameter, offering both holding power and serviceability.
