PRODUCT DESCRIPTION S.I.N.: 834-300
Permatex
®
High Strength Threadlocker RED is a high
strength anaerobic threadlocking material that 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 which 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 where future disassembly is improbable. Excellent
chemical resistance with a temperature resistance range of -
175°C to 150°C (-65°F to 300°F). OEM Specified.
PRODUCT BENEFITS
Improved Reliability
• Eliminates vibration issues
• Seals against leakage
• Prevents rusting of threads
• Cures without cracking or shrinking
Easy Application
• No mixing
• No curing outside of joint
• No torque compensation required during assembly
TYPICAL APPLICATIONS
Prevents loosening and leakage of threaded fasteners.
Particularly suitable for applications such as:
• Cylinder block
• Rocker arm studs
• Ring gear bolts
• Fan hub bolts
• Frame bolts
• Shock absorber bolts
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 (24163) and allow
30 seconds to dry. Priming is not required if the material
is an Active Metal. If unknown, its always best to use the
primer.
3. Shake the product thoroughly before use.
5. For Thru Holes, apply several drops of product onto the
bolt at the nut engagement area.
For Blind Holes, apply several drops down 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.
2. 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.
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.
