LOCTITE® 222

LOCTITE® 222 is a low-strength threadlocker that allows the adjustment of screws including countersunk head screws and set screws. Good on low-strength metals which could fracture during disassembly, e.g. aluminium or brass. The product works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces. t is proven to be tolerant of minor contamination due to industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluids.

Ideal for low-strength threadlocking of adjusting screws, countersunk head screws and set screws
Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
Especially suited to small thread sizes
Permits disassembly with hand tools

How to

Step by Step Guide

1. Preparation - Cleaning

It is recommended to use LOCTITE® SF 7063/7064 to degrease and clean surfaces prior to applying adhesive.

2. Preparation - Activation

If cure speed is too slow due to passive metals (stainless steel, aluminium and plated metals) or low temperature (below 5°C), use activator LOCTITE® SF 7240 or 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 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 into lower third of blind hole.

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.

8. Hint

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