More info

Loctite 263 is a high-strength (red) threadlocker designed for permanent locking. Unlike the blue 243, this is an industrial-grade adhesive meant for heavy-duty applications where you do not expect to disassemble the parts regularly.

The 50ml bottle is the standard size for professional and industrial maintenance.

How to Verify "100% Original" (Authenticity Check)

Because high-performance adhesives are critical for safety, verify your 50ml bottle with these steps:

Micro-Engraved Bottle: Authentic Henkel bottles feature micro-engraving in two textured areas on the bottle's shoulder. You should be able to feel and see the Loctite logo imprinted there.
Anti-Counterfeit QR Code: Newer packaging includes a unique QR code. Scan this via the Henkel website to verify the IDH (Item Number) and authenticity.
Bottle Volume (The "Air" Gap): Similar to 243, a 50ml bottle will only be about half-full of liquid. This is required because the product is anaerobic and needs oxygen in the bottle to remain in liquid form.
UV Fluorescence: The liquid contains a fluorescent agent. Under a UV (blacklight), the adhesive will glow, allowing for easy inspection of application.
