Great Product
This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Perfect for an engine rebuild, high strength that actually holds
Used this Loctite 272 red threadlocker during an engine rebuild and it did exactly what I wanted: it kept critical fasteners from backing out while dealing with heat, vibration, and repeated torque checks. Once it cures, it is seriously solid. No surprise loosening, no mess, and a little goes a long way. The 50 mL bottle is a nice size if you are doing a full rebuild or multiple projects, and the liquid applies cleanly without globbing everywhere. I had best results by cleaning the threads first, applying a small amount, and giving it proper cure time. One thing to know up front: this is high strength. If you plan to remove the fastener later, expect to need heat and the right tools. For permanent or long term assembly on an engine, that is a plus. Would buy again for any rebuild or high heat application.

Bottle is intentionally half full and is over-sized for air gap to prevent curing in bottle per Mfr
Product worked to specification withing advertised cure time as expected with all quality Loctite products. ALL thread lockers by Loctite and other manufacturers are sold in a bottle that was intentionally manufactured over-sized to allow adequate shelf life as advertised to specified expiration date, 24 months after manufacture; ATTENTION to previous buyers who have left poor reviews because they thought they received only half of what they paid for expecting a filled to the top container, if it were filled with no oxygen it would have been hard as a rock once received at your door, if your bottle looks half full, as it is supposed to be, that is because that is the only way how anaerobic adhesives like Loctite are able to be sold longer than 24 hours after manufacture; No air/oxygen = cure time/hardening begins, Adequate air gap in container = Longer Shelf Life

Not good to ship in winter.
I love Loctite and have been using their products for many years. This on came frozen from the UPS truck. I called Loctite and was told they have tested this product in much colder conditions. But to be safe, he said, I should use it within 30 days after opening. I guess I won't order any more until summer.

A completely hardened product like a stone was shipped from India. I threw it in the trash can.

The product we received was half empty, and it does not look like anything had leaked.
