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 360 degree band of threadlocker to the male fastener at the area of engagement and completely fill the thread roots - generally the width of 2-3 threads. Assemble nut and tighten to proper torque.

3b. Application - Blind Hole

Apply threadlocker to entire diameter of thread engagement area on male fastener, install fastener into blind hole, and tighten to proper torque.

4. Assembly

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

5. Disassembly

Disassemble with standard hand tools. If not possible, apply localized heat to approximately 500°F/260°C and disassemble while hot.
