Description

PRODUCT DESCRIPTION
PERMATEX Medium Strength Threadlocker BLUE is a
medium strength anaerobic threadlocking material, which
cures between engaged threads to form a unitized assembly
that resists virtually all leakage, shock and vibration. The
product is a single component, anaerobic liquid that cures
when confined in the absence of air between close fitting
metal surfaces. Ideal for all 1/4 inch to 3/4 inch diameter nut
and bolt assemblies. Excellent chemical resistance with a
temperature resistance range of -54C to +149C (-65F to
+300F). Easily removable with hand tools for servicing
requirements. OEM Specified. NSF White Book registered.
PRODUCT BENEFITS

DIRECTIONS FOR USE
For assembly
1. Clean all threads (Bolt and Hole) with a cleaning solvent
such as Permatex Brake and Parts Cleaner and allow to
dry.
2. Determine if the threads to be bonded are Active or
Inactive Metals (Ref: Cure Speed vs. Substrate on the
second page). If material is an Inactive Metal, spray all
threads with Permatex Surface Prep and allow 30 seconds
to dry . Priming is not required if the material is an Active
Metal. If unknown, it is always best to use the primer.
3. Shake the product thoroughly before use.
4. To prevent the product from clogging in the nozzle, do not
allow the tip to touch metal surfaces during application.
5. For Thru Holes, apply several drops of product onto the
bolt at the nut engagement area.
For Blind Holes, apply several drops down the female
threads into the bottom of the hole. As threads are
engaged, compressed air forces the product upwards into
the threads.
6. Assemble and tighten as usual. When tightening to
established torque values, torque compensation is not
required.
For Cleanup
1. Residual liquid films and/or fillets outside the joint are
readily soluble in Permatex Brake and Parts Cleaner.

Cured product can be removed with a combination of
soaking in Permatex Gasket Remover and mechanical
abrasion such as a wire brush.
For Disassembly
1. Remove with standard hand tools.
2. In the rare instance where hand tools do not work, because
of excessive engagement length, apply localized heat to nut
or bolt to approximately 232C (450F). Disassemble while
hot.
For Reassembly
1. Remove loose product from nut and bolt.
2. Apply primer to all threads, regardless of metal type.
3. Assemble and tighten as usual.
