Thread Lock Blue and Red, Medium and Strong Strength Threadlocker, Thread Locker for Nuts, Bolts, Fasteners and Metals, Anaerobic Curing Screw Glue to Prevent Loosening (Blue and Red)

First of all, this product is excellent. I bought this to reinforce all the large screws in my warehouse. Oh my goodness, this is fabulous. It is very easy to apply, dries quickly, and then fully cures in 24 hours. A very important point is, if you want medium strength, use the blue threadlocker because it has a firm but removable hold. And if you want a permanent formula, the red version is ideal. It is a firm and perfect fixative. Both provide a long-lasting and secure seal, ideal for both indoor and outdoor use. I like this set of bottles. They are large and how easy they are to open and close, so I will have the product for a long time. These two little friends solved my problem. Highly recommended!! If you are looking to prevent your screws from ever coming loose, this is an excellent product for you.

I used this Bellisnno thread locker set on several bolts that were constantly coming loose, and it’s been a game changer. The blue formula provides a solid medium-strength hold that’s perfect for parts I may need to remove later, while the red version is super strong and ideal for permanent fixes. The bottles are large , so you’re getting great value for the price. Application is easy with the precision tips, and the consistency is just right—not too runny or thick. It cured quickly and securely, and I haven’t had a single fastener loosen since. Highly recommend .

I bought this Bellisinno thread locker set because I needed to secure several bolts that kept loosening with use. My experience has been very positive. I used the blue bottle on parts that I wanted to keep tight but still be able to remove later, and it worked perfectly: it holds the bolts in place and when I needed to loosen them, I could do it easily with regular tools. The red one I applied on more critical joints that I never want to loosen, and it really provides a very strong and durable hold, even with vibrations. The nozzle makes application simple, the product dries quickly, and I felt confident knowing it also protects against corrosion. The 50 ml size lasts much longer than I expected too. Overall, I’m very satisfied because it solved my problem and I now have two great options in one package, depending on what I need.

Fast shipping, great product, highly recommend

This thread locker set is excellent. The blue works great for medium strength jobs where I might need to remove the bolt later, and the red gives a super strong, permanent hold. Both are easy to apply, cure well, and really keep nuts and bolts from loosening. Great value for the amount of product, and it works just like advertised. Highly recommended for DIY projects and automotive use!

I like the bottles. They have an open/close and squeeze-to-apply. Someone told me red thread locker should really bite hard and be very difficult to release. I was able to use red and still unscrew the bolt when needed but it definitely grabs and definitely seals.

I was skeptical at first because I've never heard of this brand before, but decided to save a few bucks compared to the well known name brand product, but I have to say, this stuff is great so far! The handle on our kitchen faucet is threaded on, and has less than 1/4" of thread to hold it in place. For weeks the handle was coming unscrewed, but a couple drops of the red "strong" threadlocker, and it hasn't budged again. It's been more than 2 months since I applied the threadlocker and it's still holding perfectly. The product is thinner than I expected, but that hasn't hurt its performance. I'm glad to have this stuff on hand!

Highly recommend it!
