Frequently Asked Questions

How do I remove fasteners treated with Loctite 263?

Because Loctite 263 provides a high-strength permanent bond, disassembly requires localized heat. Apply heat to the nut or bolt to approximately 250°C (482°F) and disassemble the components while they are still hot.

Is this threadlocker compatible with plastic parts?

No, this product is generally not recommended for use on plastics, particularly thermoplastic materials, as it may cause stress cracking. Always verify compatibility with your substrate before application.

Can I use this on oily surfaces?

Yes. Loctite 263 is designed with high oil tolerance and can successfully cure even when there is minor surface contamination from various cutting, lubrication, or protection fluids.

How long does it take to cure?

Cure speed depends on the substrate type, bond gap, and ambient temperature. For faster curing on passive metals or in applications with large gaps, we recommend using a Loctite Activator to ensure optimal performance
