- Description
- Technical specification
LOCTITE® 263 is a red, high strength, primerless threadlocker for permanently locking and sealing bolts, nuts and studs to prevent loosening due to vibration. It works on all metals without primer, including passive substrates such as stainless steel, aluminum and plated surfaces. Suitable for use on most oil-coated, 'as-received' fasteners without cleaning.
-
Ideal for heavy duty applications, such as studs into motor housings, where high strength is required
-
Prevents fastener loosening and leakage from shock and vibration

FAQ
Prevent vibration loosening, prevent leaks, protect threaded components from corrosion and increase the reliability of mechanical fasteners by using a LOCTITE® anaerobic threadlocking adhesive.
The standard continuous operating temperature range for LOCTITE® anaerobic adhesives is -55˚C to +150˚C.Depending on the specific application requirements, high-performance grades are also available offering increased temperature resistance. Please consult with the Henkel technical team for availability and grade selection.
Yes, LOCTITE® anaerobic adhesives and sealants become highly resistant thermoset polymers once cured, making them suitable for a vast number of applications. Consult our online product resources or contact our technical teams for further information.
Yes, these products are all anaerobic adhesives that will function in a similar way. Variations in the adhesive characteristics (viscosity, gap-fill, strength, etc.) will make them better suited to certain applications. Consult the product technical data sheets and/or LOCTITE® representatives for further information.
