Loctite 294 Threadlocker 50ml
Loctite 294 is a medium-to-high-strength green threadlocking adhesive engineered for maximum efficacy in locking and sealing threaded fasteners. This industrial-grade adhesive permanently secures and seals parts, preventing costly fluid leaks and component loosening caused by intense shock and vibration. Whether you are securing pre-assembled fasteners with thru holes or performing localized porosity sealing, this premium dimethacrylate ester acrylic adhesive provides a robust, leak-proof seal on all metal surfaces—including challenging oil-coated or re-oiled steel fasteners.
Why Choose Loctite 294 Threadlocker?
- Advanced Capillary Action: The ultra-low viscosity formula effortlessly wicks between pre-engaged threads, entirely eliminating the need to disassemble components prior to application.
- Universal Metal Compatibility: Provides exceptional bonding performance across diverse metal surfaces, including zinc phosphate, black oxide, zinc dichromate, and stainless steel.
- High Oil Tolerance: Specially engineered to deliver consistent, dependable threadlocking strength even when applied directly to oil-coated fasteners.
- Ideal for Pre-Assembled Hardware: Perfectly optimized for heavy-duty, fast-paced maintenance environments involving pre-torqued thru-hole fasteners, nuts, and bolts.
- Heat-Assisted Reversibility: While it locks parts tightly under normal operating environments, it can be reliably disassembled using standard hand tools paired with localized heat up to 250°C.
Technical Specifications
- Product Type: Dimethacrylate ester acrylic anaerobic threadlocker
- Strength: Medium to High
- Color: Dark Green (Fluorescent positive under UV light)
- Container Size: 50ml
- Certifications: Tested to the lot requirements of Military Specification Mil-S-46163A (Regional approval)
Simple Application Instructions
- Clean: For optimal results, clean all internal and external thread surfaces (bolt and hole) with a LOCTITE® cleaning solvent and allow to dry completely.
- Apply: For pre-assembled thru holes, apply several drops of the liquid threadlocker directly at the screw and body juncture. Avoid touching the bottle tip to the metal surface.
- Assemble: The formula will begin curing rapidly once it is confined in the complete absence of air between close-fitting metal surfaces. For porosity sealing applications, pre-heat the localized area to approximately 121°C, let it cool down to 85°C, and then apply the product.
Frequently Asked Questions (FAQ)
What is Loctite 294 used for?
Loctite 294 is a medium-to-high-strength anaerobic threadlocking adhesive designed for the permanent locking and sealing of threaded fasteners. It is specifically formulated to prevent fasteners and pre-assembled components from loosening or leaking due to rigorous mechanical shock, operational stress, and vibration.
Can Loctite 294 be disassembled?
Yes. It can normally be removed with standard hand tools. In rare instances where hand tools are insufficient due to excessive thread engagement length, apply localized heat to the nut or bolt to approximately 250°C and disassemble the components while they are still hot.
Does Loctite 294 work on oily surfaces?
Yes. Loctite 294 offers robust performance and dependable curing properties across a wide variety of metal surfaces, and it is highly unique for its effective performance on oil-coated or re-oiled steel fasteners where standard threadlockers might fail.
Is Loctite 294 safe for plastic components?
No. This product is an anaerobic adhesive formulated specifically for close-fitting metal surfaces. It is not recommended for use on plastic substrates—particularly thermoplastic materials—as stress cracking of the plastic could occur.
