LOCTITE® 243

Features and benefits

LOCTITE® 243 is a general purpose threadlocker that provides a medium strength bond. LOCTITE 243 works on all metals, including passive substrates such as stainless steel, aluminum 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 fluid.

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.
