Loctite high-strength threadlocker 50 ml — permanent locking for bolts & studs, corrosion resistant

Loctite 262 is a high-strength liquid threadlocker that permanently secures threaded fasteners to resist vibration and corrosion on metal assemblies.

Designed for heavy-duty applications where fasteners must not loosen, Loctite 262 delivers a permanent bond for bolts, nuts and studs across a wide range of metals, including passive surfaces such as stainless steel, aluminium and plated parts. It tolerates minor industrial contamination like engine oils and cutting fluids and provides excellent resistance to rust and aggressive chemical environments.

How does Loctite 262 keep fasteners from loosening?

Loctite 262 cures to form a strong polymer between mating threads, filling gaps and locking the assembly. The cured material resists torsional stresses and vibration that typically cause hardware to back off.

• Permanent high-strength bonding for critical joints
• Forms in confined thread spaces to prevent micro-movement
• Works on a wide variety of metals, including passive substrates
• Reduces need for mechanical locking devices like safety wire

Is this threadlocker compatible with stainless steel, aluminium, or plated surfaces?

Yes — Loctite 262 is formulated to adhere to both active and passive metal substrates, so it bonds reliably to stainless steel, aluminium and common plated finishes. Surface preparation improves long-term performance.

• Effective on passive metals thanks to specialized chemistry
• Best results when threads are clean or lightly degreased
• Tolerant of minor oil or cutting-fluid contamination
• Suitable for plated coatings and mixed-metal assemblies

What environments and chemicals can it withstand?

Loctite 262 provides strong resistance to rust and degradation in demanding chemical and environmental conditions, making it suitable for industrial assemblies exposed to solvents, oils and varying temperatures.

• High resistance to corrosion in aggressive chemical settings
• Maintains bond under moderate thermal cycling
• Resists common industrial oils and lubricants
• Helps prevent galvanic issues by sealing threaded interfaces

How should I apply and remove Loctite 262?

Apply a few drops to clean threads and assemble. Full cure is achieved anaerobically in the absence of air at the thread interfaces; removal requires heat and hand tools or controlled mechanical force depending on fastener size.

• Shake bottle, apply 1–2 drops to the bolt threads
• Assemble and allow anaerobic cure; fixture times vary by size
• Removal typically needs localized heat and standard hand tools
• Follow torque specifications after cure for reliable clamping

Who is this for? Loctite 262 is intended for engineers, mechanics, maintenance teams and fabricators who need a permanent, high-strength threadlocking solution for critical assemblies — ideal for automotive, industrial machinery, heavy equipment and other applications where fastener security and corrosion resistance are essential.
