LOCTITE® 290 - Bottle 10.0/case Wicking Grade Threadlocker
Features and Benefits
Available sizes:
Thin, low-viscosity threadlocker with the ability to flow into difficult-to-reach cracks and crevices, making it ideal for locking preassembled fasteners.
LOCTITE® 290 is a green, medium-high strength threadlocker designed for the locking and sealing of threaded fasteners. Because of its low viscosity, the product wicks between engaged threads by capillary action and eliminates the need for disassembly prior to application. This makes it ideal for sealing porosities in welds, castings and powdered metal parts. The anaerobic adhesive cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.
- Prevents fastener loosening on vibrating assemblies, e.g., pumps, gear boxes, presses
- Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
- Seals porosities in welds, castings and powdered metal parts
- Requires heat for disassembly
- Meets Mil Spec: Mil-S-46163A Type III Grade R

How to
LOCTITE 290 Threadlocker Product Overview
Step by Step Guide
1. Preparation - Cleaning
It is recommended to use LOCTITE® SF 7070 to degrease and clean surfaces prior to applying adhesive.
2. Application
Assemble nut and bolt. Dispense a low-viscosity wicking grade threadlocker, such as LOCTITE 290, at the nut and bolt juncture.
3a. Disassembly - Hand Tools
Disassemble with standard hand tools.
3b. Disassembly - Heat
If disassembly is not possible using normal hand tools, apply localized heat to approximately 500°F/260°C. Disassemble while hot with standard hand tools.
Hint
For the disassembly of corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
