LOCTITE 243 / 5g

LOCTITE 243 is a medium‑strength, blue anaerobic threadlocker that seals and secures threaded fasteners, preventing loosening from shock and vibration.

Recommended Uses

• Metals (steel and alloys) and passive metals (stainless steel, aluminum, zinc‑plated surfaces)

• Threadlocking and fastener securing in vibration‑prone assemblies (pumps, gearboxes, presses)

• Lightly contaminated surfaces: Effective on slightly oily substrates (engine oil, corrosion‑preventive oil, cutting fluids)

Key Properties

• Anaerobic Cure: Cures in absence of air

• Strength: Medium, allowing disassembly with standard hand tools

• Thixotropic: Non‑drip on vertical surfaces

• Fluoresces: For easy inspection under UV light

• Primer‑free: No pre‑treatment required

• Color: Blue
