Loctite-270 Thread Locker (50ml)

admin — Sun, 11 Jan 2026 02:54:43 +0000

This high-strength threadlocker permanently secures and seals bolts, nuts and studs to prevent loosening due to shock and vibration. It’s perfect for all metals, including passive substrates, and is tolerant of light coatings of rust-preventative oils and minor contamination without needing to be cleaned.
When you need to permanently lock assemblies that must not come loose, LOCTITE® 270 is a great choice. This high-strength threadlocker has maximum efficacy in the securing and sealing of bolts, nuts and studs to prevent loosening due to shock and vibration. It works on all metals without the need for a surface activator or primer – including passive substrates like stainless steel, aluminium and plated surfaces – and can cure through light coatings of corrosion-prevention oils and cutting fluids without the need to clean the surfaces prior to application. The lock might be permanent, but it can still be disassembled: simply heat to 300°C (572°F) and remove while still hot.

LOCTITE® 406 -Instant Adhesive(20gm)

1-part, exceptionally low-viscosity instant adhesive forming an ultra thin adhesive film for smallest adhesive gaps in seconds (fast-fixturing). Suitable for plastics and elastomeric materials.

LOCTITE® 406 is a low-viscosity instant adhesive designed especially for the fast bonding of plastics and rubbers. It fixes the adhering components in seconds and hardens very quickly, forming an ultra thin bond. Using the primer LOCTITE® SF 770, the assembly of difficult-to-bond (PP, PE, PTFE) materials is possible.

Rapid fixture time on plastic and rubber, including EPDM
Assembles difficult-to-bond materials using LOCTITE SF 770 primer
Very low viscosity product for small gaps
Reduced hazardous ingredients for improved occupational safety

Loctite-290 (50ml) Threadlocker

admin — Wed, 12 Mar 2025 07:29:46 +0000

Thin, low-viscosity threadlocker has the ability to flow into difficult-to-reach cracks and crevices, making it ideal for locking preassembled fasteners.

LOCTITE® 290 is a green, medium-high strength threadlocker designed for the locking and sealing of threaded fasteners. Because of its low viscosity, the product wicks between engaged threads by capillary action and eliminates the need for disassembly prior to application. This makes it ideal for sealing porosities in welds, castings and powdered metal parts. The anaerobic adhesive cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.

Prevents fastener loosening on vibrating assemblies, e.g., pumps, gear boxes, presses
Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
Seals porosities in welds, castings and powdered metal parts
Requires heat for disassembly
Meets Mil Spec: Mil-S-46163A Type III Grade R
