Choosing the right threadlocker for the application
How do I decide which threadlocker to use?
Loctite® threadlockers are available in many grades to
satisfy a wide range of applications. To make grade selection
easy, the grades are color- coded to help you identify one
threadlocker from the other.

The application method for blind hole assemblies
requires that the product be applied to both parts. If
the product is applied to the fastener only, air pressure
will force the liquid threadlocker to escape as you
torque down.
Yes, Henkel has threadlockers for applications below
300°F and between 300°F to 450°F. One example is
Loctite® 246™, a medium strength product for
temperatures up to 450°F. Other high temperature
products can be found in the Properties Chart.
There are several Loctite® products with oil -cutting
capabilities. These include Loctite® 243™, 246™, 266™
and 294™ threadlockers. Use the Properties Chart to
choose the one that is right for your application.
Loctite® 2440™ (medium strength) and 2760™ (high
strength) threadlockers are the latest and best
technology, enabling the assembly of inactive metals
without the need to use a primer. These products are
ideal for use on metals such as stainless steel, zinc,
magnesium, black oxide, cadmium, anodized
aluminum, passivated titanium, and others.
Most anaerobic adhesives attain full cure in around 24
hours but will fixture in less time. For cure speed of the
various products, refer to the Properties Chart or to the
Technical Data Sheets (TDS).
For plastic fasteners, only use the Loctite® 425™ Assure™
Instant Adhesive, a surface curing threadlocker.
Primers help speed the curing process for faster return
to service. For this reason, they can be used in any
application but are most often used on less active metal
surfaces. Alternatively, the use of Loctite® 2440™ and
2760™ primerless products provides a fast cure on
inactive surfaces.
