Excellent product, works exactly as discribed. Threads hold well, and take moderate force to remove, compared to no loctite.

Loctites:
Blue = removable
Red = almost permanent
Green = permanent/never remove

Purchased this for several uses. One for a screw-type pin on a 1911 sight that always wiggled loose after 100-ish rounds. Haven't had an issue since. Also have used it on other projects around the house and has worked every time. Please note that the blue is the "non-permanent" type and red is the "permanent" one. Make sure you choose the correct type for your application. Sometimes the blue does take quite a bit of wrestling to get it to shear though. Also, the Loctite is very runny, so I would highly suggest laying down some newspaper or pouring in a little cup or plastic ramekin and use a q-tip or toothpick to get on threads.

When it comes to accessories that bolt on to weapons, one should always apply loctite to the screw attachments. I've used loctite blue over the years on multiple rifles, mg's etc. and none have ever had any issues despite heavy firing schedules. I would not hesitate to buy again.

▼ The instructions say the products "sets in 10 minutes," but I had a lot of trouble with that part. The first few times I used this product, the solution never hardened--it stayed moist for a very long time. I assumed I was doing something wrong, but it wasn't totally obvious.

▲ The trick is to SHAKE VERY WELL BEFORE USING. I had only shaken the product somewhat--obviously not well enough.

▲ To be fair, the instructions do indeed say, "Shake well before use." However, this appears to be a very critical step, so I think it should be emphasized on the packaging.

Let's see...

Magpul vertical grip secured with Loctite Blue - check!

Vortex Strikefire secured within its high mount by Loctite Blue - check!

Quad rail secured in place by Loctite Blue - check!

Streamlight Polytac secured in offset mount by Loctite Blue - check!

... and so much more to come.

Loctite Blue is the perfect product to make sure that there is a no slip connection between bolts and their receivers, and it is outstanding for use with firearms as the stuff withstands the beating and vibration without a second thought. A little goes a long way, so use sparingly.

At the range two days ago, I found two set screws laying on the range floor of my lane and they were identical to the screws used to secure my AR quad rail... not a speck of a sign of Loctite Blue was on them, and I'll bet that somebody out there is not at all happy with the loose condition of their rail right now. Not gonna happen to my rigs.

If you have a need similar to what I described above, get this stuff -- you will not regret it. Highly recommended.

Have a screw that from repeated use won't stay put? Then this is what you need. Just remove the screw, place a drop of this stuff on the thread, then replace screw. Screw will stay in place from then on! Just a simple torque with a screw driver and the stuff breaks up for easy removal. A must for the weekend DIY!

The front door knob pulled off half a dozen times and was replaced twice. Thought this might be worth a try. It's been around ten weeks since the repair and my small frustrations are fading memories.

This is the Loctite that holds strong but can be easily removed with a little muscle. The red kind on the other hand cannot be removed without a lot of effort. So if you need something to hold a screw in place but still be able to remove it when you need to this the stuff you need.
