LOCTITE® 262

Name: LOCTITE® 262
Brand: LOCTITE

Features and Benefits

This 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 fluoresces under UV light – great for quality control.

Vibration resistant
Fluorescent under UV for quality control
Suitable for all metal fasteners

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.

Frequently Asked Questions

Prevent vibration loosening, prevent leaks, protect threaded components from corrosion and increase the reliability of mechanical fasteners by using a LOCTITE® anaerobic threadlocking adhesive.

The standard continuous operating temperature range for LOCTITE® anaerobic adhesives is -55˚C to +150˚C.Depending on the specific application requirements, high-performance grades are also available offering increased temperature resistance. Please consult with the Henkel technical team for availability and grade selection.

Yes, LOCTITE® anaerobic adhesives and sealants become highly resistant thermoset polymers once cured, making them suitable for a vast number of applications. Consult our online product resources or contact our technical teams for further information.

Yes, these products are all anaerobic adhesives that will function in a similar way. Variations in the adhesive characteristics (viscosity, gap-fill, strength etc.) will make them better suited to certain applications. Consult the product technical data sheets and/or LOCTITE® representatives for further information.
