Our Loctite products are sourced exclusively from Henkel USA. As an authorized Loctite Master Distributor, we ensure product authenticity and traceability. Batch numbers, certificates of compliance and analysis are available upon request.

LOCTITE 271 is a red, low viscosity, methacrylate-based threadlocking adhesive with high strength. With steel fixture time of 10 min, brass 5 min and stainless steel 15 min. Can tolerate slight contaminations of industrial oils. Suitable for all metal fasteners. Breakaway torque on M10 bolts of 26 Nm. Fluoresces under UV light. Perfect for temperatures between -65 °F - 360 °F (-54 °C - 182 °C). LOCTITE 271 is designed for the permanent locking and sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. LOCTITE 271 adds 3,000 PSI holding power on slip and press fit assemblies. Typical applications include the locking and sealing of large bolts and studs (up to M25). Replaces set screws and snap rings. Locks against vibration loosening. Removable with heat and hand tools. For fasteners up to 1" (25mm) in size. This high-strength thread locker is tested to the lot requirements of Military Specification Mil-S-46163A. MIL-SPEC (Military standard or Military-SPEC) adhesive are products that meet or exceed the US defense standard, a measure of quality set to standardize the expectations of all products supplied to the US Military. Each lot is also tested by the ASTM (American Society for Testing and Materials), a body of skilled personnel that specializes in testing materials and generating standards of quality.

  • RELIABLE ADHESION: Works on all metals, including passive substrates (e.g. stainless steel, aluminum, plated surfaces) with improved oil tolerance.
  • REMOVABLE WITH HEAT: Designed for securing parts that must withstand heavy shock, vibration, or extreme chemical or environmental conditions. Localized heating and hand tools are required to separate parts.
  • MULTI-PURPOSE APPLICATIONS: Frame brackets, suspension fasteners, shock absorber mounts, wheel studs. Ideal for as-received fasteners up to 1" (25 mm) in size.
  • CONVENIENT CURING: Sets in just 10 minutes & is fully cured in 24 hours.
  • LOCTITE Threadlocker 271 is a high strength, red threadlocker for heavy-duty applications. Especially well-suited for permanently locking studs and press fits. Adds 3,000 psi holding power on slip and press fit assemblies.

Loctite 271 Heavy-Duty Threadlocker Product FAQ

What is this heavy-duty threadlocker used for?

Loctite 271 is engineered for permanent locking of threaded fasteners in high-stress environments. It is used on bolts, studs, and other metal fasteners in engines, pumps, and heavy machinery. The cured adhesive prevents loosening from shock and vibration. It's designed for applications where disassembly is not expected.

Can fasteners be removed after applying Loctite 271?

Yes, but removal requires heating the fastener to around 500°F before using standard tools. This breaks down the cured adhesive and allows safe disassembly. Use proper safety precautions when applying heat. The strength of this product ensures components stay locked under load.

What conditions does this product resist after curing?

After full cure, it withstands temperatures from -65°F to 300°F and resists oil, transmission fluid, and industrial solvents. It also helps prevent rust and corrosion between metal threads. These features make it a trusted choice for powertrains, pumps, and vibration-prone assemblies.
