Loctite Threadlocker 272 Red High-Strength Threadlocker, 50 mL Bottle — High Temp, Vibration-Resistant

Loctite 272 is a high-strength, high-temperature red threadlocker in a 50 mL liquid bottle designed to permanently secure threaded fasteners and resist vibration and heat.

Engineered for industrial and heavy-duty applications, this Loctite formulation cures quickly on a wide range of substrates, including untreated or “as received” fasteners. It forms a durable polymer that locks threads against loosening from shock, vibration and thermal cycling. Removal typically requires heat and mechanical tools, making it suited where a permanent or semi-permanent joint is desired.

How quickly does Loctite 272 cure and work on different surfaces?

Loctite 272 begins to set rapidly on most metallic surfaces, delivering handling strength faster than many anaerobic adhesives. Cure speed depends on gap size, substrate type and temperature; tighter fits and warmer conditions accelerate the cure. It bonds well to untreated fasteners but may cure slower on plated or passive surfaces.

• Fast initial set on steel and common metals
• Works on “as received” (unprepared) fasteners
• Cure rate improves with reduced gap and higher temperature
• May need surface prep for plated or oily parts

Will this threadlocker withstand high temperatures and vibration?

Yes — Loctite 272 is formulated for high-temperature environments and resists loosening from continuous vibration and thermal cycling. Its cured polymer maintains thread lock where many general-purpose adhesives fail. For extreme or prolonged exposures, consult product temperature limits and test in your specific application.

• High-temp rated for demanding operating conditions
• Resists vibration and shock-related loosening
• Stable after cure across common industrial temperature ranges
• Suitable for assemblies exposed to repeated heating/cooling

How do I remove or disassemble parts secured with Loctite 272?

Because Loctite 272 is high-strength, disassembly usually requires applying heat to the joint plus mechanical leverage or hand tools. Heat softens the cured polymer, allowing the threadlocker to be broken with wrenches, pliers or impact tools. Use proper safety measures when heating assemblies and avoid overheating nearby components.

• Apply heat to the fastener area before attempting removal
• Use hand tools or mechanical force after softening
• Expect more effort than with removable-grade threadlockers
• Not recommended where frequent disassembly is required

What size, package and origin details should I know about this bottle?

This offering is a 50 mL liquid bottle convenient for workshop or maintenance use, sized to fit typical toolkits and parts benches. The container is compact—about 6 inches tall, 2.5 inches wide and 1 inch thick—so it stores easily. Manufacturing is in the United States, and the product ships as a red high-strength formula clearly identified by color and labeling.

• 50 mL liquid bottle for controlled dispensing
• Approximate dimensions: 6" height × 2.5" width × 1" depth
• Red-colored, high-strength/high-temperature formulation
• Made in the United States, packaged for workshop use

Who is this for: Loctite 272 is intended for maintenance technicians, OEM assemblers, machinists and serious DIYers who need a durable, high-temperature threadlocker that resists vibration and provides a long-lasting hold. Choose this product when you want a permanent or semi-permanent lock for metal fasteners and are prepared to use heat and tools for future disassembly. If frequent removal is required, consider a removable-grade threadlocker instead.
