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.

LOW STRENGTH –

good for adjustment screws, calibration screws, meters

and gauges, and for fasteners up to

MEDIUM STRENGTH –

tools, good for machine tools and presses, pumps and

compressors, mounting bolts, gearboxes, and for fasteners

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.
