Performs as it should
Ran a transmission stud vertically and blind on a 1934 motorcycle. Gave it ample time to cure before putting it back into service. Performing flawlessly. If it matters, trust it to Loctite!

Loctite 290/50ML Threadlocking Adhesive
Bought it for its wicking action. To seal threaded connections! Thanks!

Expiration date okay!
Love wicking Loctite 380 for already-assembled fastener sets. Don't forget necessary Loctite Primers for stainless, aluminum, or plated surfaces.... this type of threadlocker only works on "active" zinc/carbon steel without primers. Also these anaerobic Loctites will attack some plastics. Bought from seller Guruji Store 7/31/2025, and bottle received had a manufacturing date 12/27/2024 and expiration date of 12/27/2026. Given those dates, the price was right.

Check the date code.
Keep in mind that Loctite threadlockers have a shelf life. When I received my order I was unable to see the date of mfg. The expiration date was also unreadable. Learned that it is best to deal with an authorized distributor.
