- Question & answer
If you’re working with small diameter screws made of low strength metals (e.g., aluminum or brass), try LOCTITE® 222. It is ideal for low-strength threadlocking of adjustment screws, countersunk head screws, and set screws; on collars, pulleys, tool holders and controllers. It works on most metals without primer, including passive substrates such as stainless steel, aluminum and plated surfaces. It also cures through light coatings of corrosion prevention oils without having to clean the parts.

How to use
It is recommended to use LOCTITE® SF 7070 to degrease and clean surfaces prior to applying adhesive.
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).
Apply liquid threadlocker to the engagement area. For manual dispensing the use of a peristaltic handgun is recommended to ensure a consistent application volume.
Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.
Apply into lower third of blind hole.
Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
Disassemble with standard hand tools.
For the disassembly of corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
