TRADITIONAL FASTENING METHODS LEAVE GAPS,
LOCTITE^® THREADLOCKERS FILL THEM

Mechanical locking devices (such as split washers, nylon nuts, etc.) were invented to solve the common loosening problem in most threaded assemblies. The reality is that they don't maintain clamp load as assemblies "locked" with mechanical devices often loosen under vibration, thermal expansion, and/or improper torque. Why? Because mechanical devices don't fill the gaps between the engaging threads.

By bonding the thread roots and filling all of the gaps, eliminating side-to-side movement, LOCTITE^® Threadlockers have dramatically increased the reliability of threaded assemblies by preventing fastener loosening – a leading cause of catastrophic equipment failure.

LOCTITE^® Threadlockers solve common challenges related to threaded fasteners in electric motors.

HOW TO SELECT THE RIGHT LOCTITE^® THREADLOCKER

There are three things to consider when choosing a Threadlocker, and the color is vital, as it represents strength:

1. Strength
   • Low Strength (Purple)
   • Medium Strength (Blue) – most applications can be served with blue Threadlocker
   • High Strength (Red)
2. Fastener Size
   • From < ¼" (6 mm) fasteners on up, there's a LOCTITE^® Threadlocker
3. Application Methods
   • Pre-Assembly: Most LOCTITE^® liquid threadlockers are designed to be applied at the moment parts are assembled
   • Post-Assembly: Wicking grade formula can be used on parts that are already assembled
