Permatex Penetrating Threadlocker

Permatex Penetrating Threadlocker is a low-viscosity, wicking-grade thread locker (also called threadlocking adhesive) for fasteners that are already assembled. Its thin consistency lets it creep into the threads by capillary action. You don't need to disassemble the fastener first, which saves time on repairs and maintenance.

Key Features:

• Wicking, penetrating formula that flows into the threads of pre-assembled fasteners
• Locks and seals threaded fasteners to resist loosening from vibration and shock
• Helps prevent rust and corrosion in the threads
• Suited to small fasteners, set screws, and tight-tolerance assemblies
• Made by Permatex, a long-established brand in automotive, powersports, marine, and general maintenance chemicals

Use it on clean, dry threads. Permatex Penetrating Threadlocker is a good choice for engine, chassis, and equipment fasteners that need extra security. Check the individual product listing for the strength grade and package details of each variant.
