LOCTITE® 270 Threadlocker 50ml

LOCTITE® 270 is a high-strength green threadlocker engineered for maximum efficacy in securing and sealing threaded fasteners. This industrial-grade anaerobic adhesive permanently locks bolts, nuts, and studs, preventing costly loosening caused by intense vibration and shock. Whether you are securing heavy-duty machinery or standard assemblies, this premium green threadlocker provides a robust, leak-proof seal on all metals—including passive substrates like stainless steel and aluminum.

Why Choose LOCTITE® 270 High-Strength Threadlocker?

• Maximum Vibration Resistance: Prevents the loosening of critical vibrating assemblies such as pumps, gearboxes, and heavy presses.
• Universal Metal Compatibility: Delivers high performance on active metals (brass, copper) and passive substrates (stainless steel, aluminum, plated surfaces).
• Industrial Oil Tolerance: Formulated to successfully cure despite minor surface contamination from motor oils, cutting fluids, and anti-corrosion lubricants.
• Heavy-Duty Permanent Locking: Ideal for high-strength requirements, such as securing studs into motor housings and nuts onto pump housings.
• Extreme Temperature Resistance: Maintains a reliable, long-lasting seal in high-temperature environments and can be disassembled by heating to 300°C.

Technical Specifications

• Product Type: Anaerobic Threadlocking Adhesive

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a LOCTITE® cleaning solvent and let dry.
2. Apply: Apply several drops of the liquid threadlocker to the nut engagement area (for through holes) or the lower third of the internal threads (for blind holes).
3. Assemble: Assemble and tighten the fasteners as required. The anaerobic formula will begin curing once confined between the close-fitting metal surfaces in the absence of air.

Frequently Asked Questions (FAQ)

What is Loctite 270 used for?

Loctite 270 is a high-strength threadlocking adhesive designed for the permanent locking and sealing of threaded fasteners. It is specifically formulated to prevent fasteners from backing out or leaking due to heavy shock, mechanical stress, and severe vibration.

Can Loctite 270 be disassembled?

Yes, though it is a permanent high-strength threadlocker, it can be disassembled if necessary. To remove, apply localized heat to the nut or bolt assembly until it reaches approximately 250°C to 300°C, and then disassemble the fasteners using standard hand tools while the metal is still hot.

Does Loctite 270 work on stainless steel?

Yes. Loctite 270 offers robust curing performance across all metals. It is highly effective on both active substrates like brass and copper, as well as passive substrates like stainless steel, aluminum, and plated surfaces.

Is Loctite 270 safe for food processing environments?

Loctite 270 is registered to NSF Category P1 (Reg. No. 123006). This means it is approved for use as a sealant in and around food processing areas, provided there is no possibility of direct food contact.
