How to

Step by Step Guide

1. Preparation - Cleaning

It is recommended to use LOCTITE SF 7070 to degrease and clean surfaces prior to applying threadlocker.

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 LOCTITE SF 7649 activator. Allow to dry.

3a. Application - Through Hole

Apply a few drops of liquid threadlocker to the thread engagement area. Assemble nut and tighten to proper torque.

3b. Application - Blind Hole

Apply several drops of liquid threadlocker into lower third of blind hole, as well as a few drops onto male threads, and then install male threads. Tighten to proper torque.

4. Assembly

Assemble and tighten to proper torque requirement. If several screws/small bolts are being assembled, torque them down to the correct value within the fixture time window.

5. Disassembly

Disassemble with standard hand tools.
