Frequently Asked Questions

Is Loctite 263 suitable for all metal surfaces?

Yes, this threadlocker is versatile and works exceptionally well on active metals such as brass and copper, as well as passive substrates like stainless steel and various plated surfaces.

How do I remove fasteners treated with Loctite 263?

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

Can this product be used on plastic fasteners?

Loctite 263 is not recommended for use on plastics, particularly thermoplastic materials, as it may cause stress cracking. Always confirm substrate compatibility before application.

What should I do if the cure speed is too slow?

If you are working in large gaps or need a faster cure time, you may use an appropriate Loctite activator (such as 7471, 7649, 7088, or 7091) on the surface prior to applying the adhesive.
