Loctite 271 Acrylic Anaerobic Threadlocker Red 50ml
Loctite 271 Acrylic Anaerobic Threadlocker Red 50ml is a high-strength red anaerobic threadlocker engineered for maximum efficacy in locking and sealing threaded fasteners. This industrial-grade adhesive permanently locks bolts and nuts, preventing costly equipment failure or fluid leaks caused by severe vibration and shock. Whether you are securing heavy machinery bolts or automotive suspension components, this premium threadlocking adhesive provides a robust, leak-proof seal on all metal fasteners—including passive substrates like stainless steel and plated surfaces.
Why Choose Loctite 271 Permanent Strength?
- High Vibration Resistance: Prevents loosening, leaks, and corrosion by completely filling the gaps between mating threads.
- Universal Metal Compatibility: Effective on all metal fasteners, including standard steel, brass, and challenging passive materials like stainless steel.
- Chemical & Oil Tolerance: Formulated to withstand exposure to industrial oils, automotive fluids, and mild chemical environments without breaking down.
- Heavy-Duty Structural Defense: Ideal for permanent applications where fasteners must endure continuous high-load mechanical stress.
- High Thermal Stability: Maintains a dependable, iron-clad seal in operating environments ranging up to 150°C.
Technical Specifications
- Product Type: Acrylic Anaerobic Threadlocking Adhesive
- Strength: High Strength / Permanent
- Color: Red (Liquid)
- Container Size: 50ml
- Certifications: Meets military specification Mil-S-46163A; UL Classified for regular commercial applications.
Simple Application Instructions
- Clean: For optimal results, clean all internal and external surfaces with a Loctite cleaning solvent (or a standard degreaser) and let dry completely.
- Apply: Apply several drops of the liquid threadlocker directly to the bolt at the nut engagement area.
- Assemble: Assemble and tighten the parts as required. The formula will begin curing rapidly once it is confined between closely fitting metal surfaces in the absence of air.
Frequently Asked Questions (FAQ)
What is Loctite 271 used for?
Loctite 271 is a high-strength, low-viscosity threadlocking adhesive designed for the permanent locking and sealing of threaded fasteners. It is specifically formulated to prevent heavy-duty bolts, studs, and press-fits from loosening or backing out due to severe shock, thermal expansion, and operational vibration.
Can Loctite 271 be disassembled?
No, it cannot be disassembled with standard hand tools alone under normal conditions. Because of its high permanent strength, disassembly requires localized heat application to approximately 250°C (482°F) to soften the cured polymer matrix before the parts can be safely torqued and separated.
Does Loctite 271 work on stainless steel?
Yes. Loctite 271 offers robust performance across all standard metal fasteners. It is highly effective on both active metals (such as brass, copper, and iron) as well as passive surfaces (such as stainless steel, aluminum, and plated fasteners), though passive materials may require a slightly longer full cure time.
Is Loctite 271 safe for commercial plumbing or industrial environments?
Loctite 271 is heavily relied upon across automotive, manufacturing, and industrial assembly lines. It is certified to strict military standards for mechanical reliability, though it should not be utilized in pure oxygen, chlorine-rich environments, or applications involving food-contact or potable water unless explicitly rated on a localized project scale.
