LOCTITE threadlockers are high-performance adhesives designed to secure threaded fasteners such as nuts, bolts, and screws. They help prevent loosening caused by vibration, shock, and temperature changes while protecting threads against corrosion. Available in different strengths and formulations, LOCTITE threadlockers are ideal for industrial machinery, automotive applications, equipment assembly, and maintenance. Choose the right threadlocker for your fastener size, strength requirements, and service conditions to ensure reliable performance.

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.

Four Steps to Permanent Thread Security

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.
