Loctite 222 Low Strength Threadlocker
Available in 10ml, 50ml and 250ml Size Options
Description
Loctite 222 Low Strength Threadlocker (Purple coded) is recommended for use with small fasteners, that allows the
adjustment of screws including countersunk head screws and set screws.
Low-strength threadlocker for the locking and sealing of small fasteners under 6.35 mm (1/4″) in diameter.
Prevents loosening from shock and vibration, removable with hand tools.
Good on low-strength metals which could fracture during disassembly, e.g. aluminum or brass.
The product works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces.
It is proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils
and cutting fluids.

How to Use
1. Preparation – Cleaning
It is recommended to use LOCTITE® SF 7070 to degrease and clean surfaces prior to applying adhesive.
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 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
Disassemble with standard hand tools.
Hint
For the disassembly of corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
