Permatex Threadlocker

SKU 24005

Permatex Threadlockers:

Ultimate Vibrational Security for Every Fastener
Don’t let vibration, thermal expansion, or rigorous operation compromise your mechanical builds.

Permatex Threadlockers are industry-leading, anaerobic liquid and gel compounds engineered to lock threaded assemblies firmly in place. By completely filling the microscopic gaps between mating metal threads, these formulas seal out moisture, halt corrosion, and prevent catastrophic loosening.
Whether you are working on precision instrumentation, performing routine automotive maintenance, or building heavy-duty industrial machinery, there is a specialized color-coded Permatex formula built exactly for your application constraints.

Highlights

Find Your Holding Power: Color-Coded Performance Strength

🟣 Low-Strength (Purple)

* The Go-To For: Sensitive, small-diameter fasteners under 1/4" (6mm).

* Key Advantage: Secures adjustment screws, calibration meters, and gauges against mild vibration without stripping delicate threads during disassembly.

* Removal: Effortlessly releases using standard hand tools.

🔵 Medium-Strength (Blue)

* The Go-To For: General-purpose servicing and fasteners ranging from 1/4" to 3/4" (6mm to 19mm).

* Key Advantage: Reliably locks valve covers, water pumps, and oil pan bolts under everyday operational stress.

* Removal: Keeps parts tight during use but allows straightforward removal using common hand tools when servicing is required.

🟠 High-Strength / Removable (Orange)

* The Go-To For: High-vibration environments demanding maximum hold without permanent lockdown.

* Key Advantage: A modern hybrid engineering marvel providing three times the mechanical resistance of traditional blue formulas. Ideal for dirt bike cases, flywheels, and extreme-vibration components.

* Removal: Delivers heavy-duty performance but can still be backed out using standard hand tools—no intense heat required.

🔴 High-Strength / Permanent (Red)

* The Go-To For: Heavy-duty assemblies, harsh structural joints, and studs up to 1" (25mm).
* Key Advantage: Creates a semi-permanent bond optimized for ring gears, transmission shafts, and cylinder block studs.
* Removal: Built to stay put. Disassembly requires localized heat targeting roughly 500°F (260°C) to soften the polymer before hand tools can break the bond.

🟢 Penetrating Grade (Green)

* The Go-To For: Pre-assembled hardware and hard-to-reach threads.

Additional information

* Key Advantage: A ultra-low viscosity liquid designed to wick deep into pre-tightened nuts and bolts via natural capillary action. Excellent for electrical terminals and carburetor linkages.

* Removal: Varies by specific formula; generally manageable with hand tools, though heavy-duty green variations may require heat.

Specialty Formulations for Extreme Environments

* Surface Insensitive: Formulated to fully cure on passive metals and less-than-perfect surfaces. It cuts through light oil contamination and bypasses the need for chemical primers.

* High-Temperature Shielding: Specialized high-temp variations extend operational limits up to 600°F (315°C)—perfect for exhaust manifolds and heavy engine bays.

* Large Diameter Viscosity: Thickened red formulas engineered specifically to fill the wide thread tolerances found on massive bolts over 1" (25mm).

* Rapid Cure Tech: Fast-acting alternatives that completely cure in under 4 hours to minimize machinery downtime and get equipment back online fast.

## Choose Your Ideal Application Method

* Classic Liquids: Offer deep thread penetration and exceptional surface coverage for clean, flat-bench assemblies.

* No-Drip Gel Pens & Tubes: Gel formulas stay exactly where you put them. They will not run, drip, or migrate, making them the perfect mess-free option for vertical or overhead fasteners.
