Anyone have experience with green Locktite?

[Mixlesplick]

I used the blue Locktite on the grip screws on my K40. After the last four range sessions I checked the screws. They are starting to loosen. The green Threadlocker in the Brownells catalogue shows it to have 1600 psi strength over the blue with 1400 psi strength. Has anyone tried the green Threadlocker? That looks like the strongest I can get that is still removable with normal tools.

though this may not be much help, i believe my dad and I have used the green locktite as a retaining compound for keys in shaft keyways. I could be mistaken however.

All i know is that the red stuff is very tough and needs heat to remove and that it is not particually recommended for things like grip screws.

YMMV

Try red before resorting to the green. That stuff can get pretty burly to remove a screw later on.

Unless I have my colors mixed up in my old age, blue is standard, green is for already-assembled parts, like adjustment screws, and red is heavy-duty permanent and requires significant heat for disassembly. I'd stick with the blue, but clean all the threads well before using.

Blue:
Locks threaded fasteners against vibration loosening
Ideal for nut and bolt applications 1/4" to 3/4" (6mm to 20mm)
Prevents threads from rusting and leaking
Removable with hand tools for easy disassembly


Green:
Prevents vibration loosening of pre-assembled fasteners
For use on electrical connectors, instrumentation, screws, and set screws
Ideal for fasterners #2 - 1/2"


Red:
OEM specified as 271
High temperature, high strength for heavy duty applications
Designed for larger fasteners 3/8" to 1" (9.5mm to 25mm)
Locks studs, bushings and large fasteners against vibration loosening
Strengthens slip and light press fits
Removable with heat and hand tools


Blue: Can be removed with hand tools
Red: Apply heat to remove
Green: Apply heat to remove


Seems to me there are a couple more, Purple that was similar to Blue 's properties, and one high strength one that was meant to fill gaps

Hope it helps

There are at least two versions of Loctite green. 640 Loctite is green; is a sleeve retainer and is much stronger than red (271) Loctite.

Thanks for all your help. I didn't see that about the green being for pre-assembled fasteners and screws until I read your posts. I will try the blue again but this time I will clean and degrease the threads really well first.

Mixlesplick did you get your screen name from Jay Ward's Fractured Fairy Tales?

 

[Elarski]

I think you're on the right track by cleaning the hole and screws, and using the blue Loctite.

I used the green Loctite on the wrong application; that stuff needed a major amount of heat to seperate the two parts I used it on.

Good luck.

I haven't heard the term "Fractured Fairy Tales" before. I googled it and I am still a little confused...but that's not unusual.

I got this name from the Superfriends cartoon where the superfriends were always fighting the archvillains. There was one villain that had to be tricked into saying his name backwards in order to send him back to another dimension. I remembered his name as Mixlesplick although I never could recall what the name was exactly. Too much sugary cereal during Saturday morning cartoons I guess.

I used to walk around my job and give my coworkers a funny look and then say, "Mixlesplick!" and walk away. It was kind of fun for a while and I really liked that word so here I am today.

Isn't Fractured Fairy Tales from the Rocky and Bullwinkle cartoons?

640 Loctite is green; is a sleeve retainer and is much stronger than red (271) Loctite.

That's the one I have always used. Didn't even know about the other one.

Stay with the Blue

hey members great job letting people know what color does what

Be sure to use some acetone to clean the threads before you do the assembly. I did it recently for the set screws on the Advanced Technology scope mount on my .303 Enfield and it seems to be holding quite well.

Better to go by stock number. Even Brownells carries three different greens of different strengths and applications. There are multiple reds, regular, high fill, and high temperature that I can think of offhand.

I used some green off-brand loctite on a set screw on my rear sight. I put some on it, fired five shots to find zero, and couldn't move the sight. Oops. I did use the green on my already assembled grip bushings, I didn't want to take them out and use red. I may need to remove this rear sight before long, I'll let yall know how that goes.
