Loctite 275 Threadlocker 50ml

Loctite 275 Threadlocker 50ml is a high-strength, high-viscosity green threadlocking adhesive engineered for maximum efficacy in permanent assembly. This industrial-grade adhesive permanently locks and seals threaded fasteners, preventing costly loosening, leaks, and corrosion caused by shock and vibration. Whether you are securing large bolts or studs (M25 and larger), this premium methacrylate-based threadlocker provides a robust, leak-proof seal on all close-fitting metal surfaces—including slightly oil-contaminated substrates.

Why Choose Loctite 275?

• High Strength & Permanent Lock: Formulated specifically for applications where the fastener must absolutely not loosen over time.
• High Viscosity & Thixotropic: The thick formula prevents the migration and dripping of the adhesive after application.
• Oil Tolerant: Demonstrates a reliable cure even when faced with slight contamination from industrial oils.
• Engineered for Large Fasteners: Optimized to fill larger gaps, making it the ideal choice for heavy-duty bolts and studs M25 and larger.
• Vibration & Corrosion Resistant: Seals out moisture and environment to completely prevent thread corrosion and movement.

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a LOCTITE® cleaning solvent and allow to dry.
2. Apply: For thru holes, apply several drops onto the bolt at the nut engagement area. For blind holes, apply several drops down the internal threads to the bottom of the hole. (Note: Do not let the nozzle tip touch metal surfaces).
3. Assemble: Assemble and tighten parts as required. The formula will begin curing anaerobically once it is confined in the absence of air between the close-fitting metal surfaces.

Frequently Asked Questions (FAQ)

What is Loctite 275 used for?

Loctite 275 is a high-strength threadlocking adhesive designed for the permanent locking and sealing of threaded fasteners. It is specifically formulated to prevent large bolts, studs, and heavy-duty fasteners from loosening or leaking due to intense shock, vibration, and mechanical stress.

Can Loctite 275 be disassembled?

No, it cannot be disassembled with standard hand tools alone due to its high strength. To disassemble, you must apply localized heat to the nut or bolt to approximately 250°C and disassemble the components while they are still hot.

Does Loctite 275 work on all materials?

It is highly effective on close-fitting metal surfaces and can tolerate slight contamination from industrial oils. However, it is not normally recommended for use on plastics, particularly thermoplastic materials, as stress cracking of the plastic could result.

Is Loctite 275 safe for any environment?

This product is not recommended for use in pure oxygen and/or oxygen-rich systems, and it should never be selected as a sealant for chlorine or other strong oxidizing materials. Always consult the Material Safety Data Sheet (MSDS) before introducing it to specialized chemical environments.
