Anaerobic Fastener Protection

Engineered Fastener Security Under Extreme Vibration

Protect threaded assemblies from loosening, shock loads, and thread corrosion. Genuine Loctite anaerobic threadlockers convert liquid resin into durable thermoset plastic inside metal thread engagements.

Selection Guide

Formulations for Every Fastener Size

Select the correct strength grade based on fastener diameter, operating temperature, and scheduled maintenance requirements.

Low Strength
Medium Strength
High Strength

Precision & Small Screws

Machine Bolts & Pumps

Heavy Equipment & Studs

Ideal for fasteners under 1/4 inch, instrumentation screws, and carburetors. Allows straightforward disassembly with standard hand tools without thread stripping.

The universal standard for machine tools, gearboxes, and press equipment. Resists intense machine vibration while permitting maintenance teardown with conventional hand tools.

Permanent retention for suspension bolts, motor mounts, and heavy industrial machinery up to one inch. Requires localized heating for component disassembly.

Clean Thread Surfaces

Dispense Compound

Assemble to Torque

Anaerobic Polymerization

Remove particulate matter, residual cutting oils, and grease using industrial solvent degreasers for optimal metal contact.

Apply liquid anaerobic threadlocker onto the engaged thread zone of the bolt and within the internal nut threads.

Tighten the fastener to designated engineering torque specifications, distributing the anaerobic fluid evenly across all roots.

The fluid polymerizes completely in the absence of air and presence of active metal, creating a sealed 100% unitized assembly.
