Loctite 274 Acrylic Anaerobic Threadlocker Blue 50ml

Loctite 274 Acrylic Anaerobic Threadlocker Blue 50ml is a medium-strength blue threadlocking adhesive engineered for maximum efficacy in threadlocking and sealing. This industrial-grade adhesive permanently locks and seals threaded fasteners, preventing costly loosening and leakage caused by shock and vibration. Whether you are securing thru-holes or blind holes, this premium 1-part dimethacrylate ester acrylic adhesive provides a robust, leak-proof seal on all close-fitting metal surfaces—including steel, black oxide, and zinc dichromate.

Why Choose Loctite 274 Medium Strength?

• Vibration Protection: Prevents fasteners from loosening or leaking when subjected to heavy operational shock and vibration.
• No-Mix Convenience: A single-component formula that requires zero mixing, ensuring an effortless, clean application.
• Visual Inspection: Fluoresces positive under UV light, allowing for easy quality control and inspection after application.
• Standard Tool Removal: Offers medium-strength holding power that eliminates the need for extreme measures during standard maintenance.
• Easy Disassembly: Designed to be easily removed with standard hand tools under normal conditions.

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a LOCTITE® cleaning solvent and let dry. (If working with inactive metals or slow cure speeds, spray threads with Activator 7471™ or 7649™).
2. Apply: Shake thoroughly. For thru-holes, apply several drops to the bolt at the nut engagement area. For blind holes, apply several drops down the internal threads to the bottom of the hole. For sealing, apply a 360° bead to the leading male threads, leaving the first thread free.
3. Assemble: Assemble and tighten the parts as required. The formula will begin curing once confined in the absence of air between close-fitting metal surfaces.

Frequently Asked Questions (FAQ)

What is Loctite 274 used for?

Loctite 274 is a medium-strength anaerobic threadlocking adhesive designed for locking and sealing threaded fasteners. It is specifically formulated to prevent nuts, bolts, and fittings from loosening and leaking due to heavy shock, stress, and operational vibration.

Can Loctite 274 be disassembled?

Yes. Loctite 274 is specifically designed to allow for normal disassembly using standard hand tools. In rare instances where hand tools are insufficient due to excessive thread engagement length, localized heat can be applied to the nut or bolt to approximately 250°C to disassemble while hot.

Does Loctite 274 work on plastic?

No. Loctite 274 is an anaerobic adhesive meant for metal-to-metal contact. It is not normally recommended for use on plastics, particularly thermoplastic materials, as it could result in stress cracking of the plastic.

Is Loctite 274 safe for oxygen-rich environments?

No. 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) for safe handling details.
