LOCTITE 272 High Strength High Temperature Threadlocker, 50ml, for Engine-Adjacent and Heat-Exposed Critical Fastener Applications
Standard high strength threadlockers lose a significant proportion of their retention strength when exposed to sustained elevated temperatures, which makes them unsuitable for fasteners in heat-exposed locations where vibration and thermal cycling combine to create the most demanding conditions for fastener retention. Supplied by JHEARs Aerospace, LOCTITE 272 is the high strength, high temperature threadlocker formulated to maintain its permanent retention properties under the sustained heat that would degrade a standard formula, making it the correct product for critical fasteners near engines, exhaust systems, and other high-temperature, high-vibration locations where the fastener must not work loose in service.
Once cured, LOCTITE 272 bonds fasteners permanently and removal typically requires the application of localised heat combined with hand tools, which is precisely the intended performance for hardware that must remain locked under all operational conditions. For engineers and mechanics who understand that a fastener in a high-heat, high-vibration location secured with the wrong threadlocker grade is a maintenance event and a safety risk waiting to happen, LOCTITE 272 is the specification-correct choice that provides the permanent lock the application demands.
Spec: LOCTITE 272 high strength high temperature threadlocker, 50ml. Permanent grade anaerobic formula with elevated temperature resistance. Suitable for M6 to M20 fasteners in high-heat, high-vibration applications near engines, exhaust systems, and thermally stressed assemblies. Removal requires heat and hand tools.
Who this is for: Aircraft engineers and mechanics securing critical fasteners in engine bays, exhaust system attachments, and heat-exposed structural locations, MRO technicians working on assemblies where both high vibration and elevated operating temperatures are present simultaneously, and engineering professionals who need a permanent, temperature-resistant threadlock on fasteners that must not move under any operational condition.
FAQ
What is the maximum service temperature of LOCTITE 272?
LOCTITE 272 is rated for continuous service temperatures up to 150 degrees Celsius, with intermittent peak resistance up to 200 degrees Celsius. This makes it suitable for fasteners in locations that regularly exceed the 120 to 150 degree Celsius threshold at which standard threadlockers begin to lose significant retention strength. Refer to the LOCTITE 272 technical data sheet for full temperature-versus-strength performance data.
Is LOCTITE 272 the same strength as LOCTITE 271 or 277?
LOCTITE 272 shares the high strength permanent-grade retention level of other red/brown high strength threadlockers in the Loctite range but is specifically formulated for elevated temperature service. LOCTITE 271 and 277 are also high strength but are rated for standard operating temperatures. For engine-adjacent and heat-exposed applications, 272 is the correct product where temperature resistance is a requirement alongside high retention strength.
How should I remove a fastener secured with LOCTITE 272 at maintenance?
Apply localised heat to the fastener and surrounding material, typically in the range of 200 to 250 degrees Celsius, to soften and degrade the cured adhesive bond, then use appropriate hand tools to break the fastener free while the bond is heat-softened. Allow the fastener and joint to cool before inspection and reapplication of fresh threadlocker if reinstallation is required.
Why should I purchase my high-temperature threadlocking products from JHEARs Aerospace?
At JHEARs Aerospace, we supply professional-grade Loctite threadlocking products including high-temperature grades selected for use in aviation maintenance and engineering environments where fastener retention under heat and vibration is a safety-critical requirement. Our range is sourced to ensure product authenticity and specification compliance.
