LOCTITE® 243

Features and benefits

LOCTITE® 243 is a blue, general purpose threadlocker that provides a medium-strength bond. It works on all metals without primer, including passive substrates such as stainless steel, aluminium, and plated surfaces. Suitable for use on most oil-coated, 'as-received' fasteners without cleaning.

How to use

1. Preparation - Cleaning

It is recommended to use LOCTITE® SF 7063, SF 7064, or SF 7070 to degrease and clean surfaces prior to applying threadlocker 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 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 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

6. Assembly

Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
