Loctite37643 Blue Medium Strength Threadlocker Stick - 9 g

Q: Does the stick ever dry out? What is the longest you have had it open and it still works as expected for you?

Loctite Rep said the "stick" shelf life from date of manufacture is 4 years. Rep said Manufacture date is 2nd and 3rd series of numbers/ letters in the batch number. Example Batch Number example L3 7 B AC569. Number 7 will indicate last number of the year No clarification was given if 2017 would be 7 or 17. And and letter B will indicate month, B = February.

Q: INeed to remove the bolt, can you do it with tools? Liquid says yes, reviewers say stick is permanent. Can't be permanent for my purpose .

loctite says: Threadlocker Blue 242® is great for Securing nuts and bolts from accidental loosening. Removes with hand tools.I say: It depends. Size of the locking area, strength and condition of the fastener. Now on a typical 5/16'' nut and bolt is a very small locking area so Blue is totally removeable as long as it's clean with no rust or burrs. Got dirt, rust, wire brush em unless their too far gone. Chase the threads on burrs. If you don't and it's a cheap grade fastener... It's gonna break and may ruin your day. Remember, this stuff turns into a crystalline structure under pressure. Sticks to everything including dirt and rust. So the impregnated rust, dirt and burrs are bigger now which causes binding upon removal. The LOCTITE 290 Wicking Grade Green is kool stuff. Apply after assembly and doesn't take much. Almost as strong as Blue, easy removal qualities and costs more. So don't spill it. Threadlocker Red 271 is for grade 8 fasteners or better. Hope this helped.

Q: Has anyone used this with macbook screws? i'm hoping it provides similar holding power to oem screws, mine have been wiggling out a lot over time.

Yes. I use this on all of my computer screws, including an older MacBook. I'm not aware of anything special about MacBook screws, or oem screws, that would make them less suitable. This is a mechanical bond, so the more threads that engage, and the finer the gap of the engagement, the better it works.

Q: Is there a max temperature for storage? Basically will it melt in my Florida garage?

Optimal storage is 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Here is the TDS: http://tds.henkel.com/tds5/Studio/ShowPDF?pid=248&format=MTR&subformat=REAC&language=EN&plant=WERCS

Building 3D printers? Voron builder dream!

If you build Vorons or 3D printers, this stuff is so good. It's not ideal to get loctite on the ABS/ASA plastic as it reacts chemically and breaks down the plastic, but with this stuff being thicker than even gel you can be confident it doesn't get where you don't want it.Use this for your 3D printer metal on metal connections.

Works great! Highly recommended!

I bought this because I needed something to carry in my small tool bag while riding motorcycles. The first trip, I had some bolts on my hand guards that were trying to walk themselves out, and were being a constant issues. I slathered the bolt up and stuck it back it, tightened it down, no more issues for the next two days of riding! This stuff is super handy, much easier to work with than the liquid stuff. I know I put blue locktite on those same bolts before I left, but apparently, it wasn't enough. This will stay in my little tool pouch that I always care riding.
