LOCTITE® 262
Features and Benefits
This red, high strength, thixotropic, anaerobic-curing threadlocking adhesive locks and seals threaded fasteners.
LOCTITE® 262 is a red, general purpose, high strength, anaerobic-curing threadlocking adhesive, which prevents threaded fasteners from loosening due to heavy shock and vibration. Ideal for applications where migration of the adhesive must be prevented. It is oil tolerant and fluoresces under UV light – great for quality control.
- Vibration resistant
- Fluorescent under UV for quality control

How to
Step by Step Guide
1. Preparation - Cleaning
It is recommended to use LOCTITE® SF 7070 to degrease and clean surfaces prior to applying LOCTITE 262 threadlocker.
2. Preparation - Activation
If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperature (below 5°C), use activator LOCTITE® SF 7649 (see cure speed vs activator graph in the TDS).
3. Application
Apply liquid threadlocker to the engagement area. For manual dispensing, the use of a peristaltic handgun or the LOCTITE® Pro Pump is recommended to ensure a consistent application volume.
4. Application - Through-Hole
Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.
5. Application - Blind Hole
Apply several drops of liquid threadlocker down the sides of the blind hole filling the lower third. Apply several drops to the bolt.
6. Assembly
Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
7a. Disassembly - Hand Tools
Disassemble with standard hand tools.
7b. 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.
