Hướng dãn sử dụng Loctite 222

1. Preparation – Cleaning

LOCTITE® 222™ is suitable for use on most “as-received” fasteners with light coatings of corrosion prevention oils without cleaning. However, for heavily oiled or contaminated fasteners, it is recommended to use LOCTITE® SF 7070™ to degrease and clean surfaces prior to applying LOCTITE 222 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.

7. Disassembly – Hand Tools

Disassemble with standard hand tools.

Hint

For the disassembly of corroded or seized parts use LOCTITE® LB 8040™ Freeze and Release.
