Loctite 290 Wicking Grade Threadlocker(bottle)

Loctite 290 Wicking Grade Threadlocker is a single-component, low-viscosity anaerobic threadlocking adhesive that delivers medium to high locking strength on threaded fasteners. What sets Loctite 290 threadlocker apart from standard threadlockers is its very low viscosity, which allows it to wick into pre-assembled threaded joints by capillary action. This means Loctite 290 wicking grade threadlocker can be applied after fasteners are already in place, eliminating the need for disassembly before treatment — a major time-saver on instrumentation, electrical, and set-screw assemblies. Available at Tapemart, your dependable Loctite distributor, genuine Loctite 290 threadlocker is ready for dispatch to workshops, OEMs, and maintenance teams nationwide.

Key Features and Benefits

•      Low-viscosity, wicking-grade formula penetrates pre-assembled threads by capillary action

•      Medium to high locking strength prevents fastener loosening from shock and vibration

•      Green, fluorescent liquid for easy visual inspection and quality control under UV light

•      Cures anaerobically — only inside the joint, in the absence of air, between close-fitting metal surfaces

•      Seals porosity in welds, castings, and powdered metal parts, preventing leaks and corrosion

•      No need to disassemble fasteners before application, reducing rework time

•      Tested to Mil-S-46163A and ASTM D5363 specifications for consistent quality

•      Effective continuous operating temperature range of -55°C to +150°C

Typical Applications

Loctite 290 wicking grade threadlocker is the go-to solution for locking and sealing threaded fasteners on equipment that is already assembled or difficult to access. Common applications include instrumentation screws, electrical connectors, and set screws on motors, gearboxes, pumps, and presses, where vibration over time would otherwise loosen the joint. It is equally effective at sealing micro-porosity in welds, die castings, and powdered metal components, preventing fluid or gas leakage through tiny surface voids. Maintenance technicians frequently favor Loctite 290 threadlocker because it can be dripped directly onto an installed fastener head without dismantling the assembly first.

How to Use Loctite 290 Wicking Grade Threadlocker

Ensure the fastener and surrounding surface are clean and free of oil or debris; use a Loctite cleaning solvent if necessary. For through-holes, apply several drops of Loctite 290 directly at the head of the screw or bolt and allow capillary action to draw the product through the threads. For blind holes or nut-and-bolt junctions, apply the product at the visible thread juncture. The anaerobic adhesive will cure once confined between the close-fitting metal surfaces in the absence of air, typically reaching handling strength within minutes and full cure within 24 hours. If disassembly is later required and cannot be achieved with standard hand tools, localized heat of approximately 260°C (500°F) will break down the cured threadlocker. Always check the official Loctite 290 technical data sheet for exact fixture and cure times relevant to your substrate.
