Which Loctite?

[GSD17]

Ok I searched and searched.

Found some great info, but not exactly what I was looking for..


I SWEAR I remember seeing a pic of a loctite that was pretty much specific for guns.

I was thinking it was green... but all the info I found on green was that it was super duper tough... more so than red..

Which is the best?

So far I think I have figured that

Blue is ok
Red is better
Green is very tough

Any I am missing?

i havent seen the version you are asking about for pistols, i have only used blue and red for automotive purposes...

curious, where would you be applying said product on your handgun?

I've had no problems with the blue. Getting everything cleaned first is the most important part, no need for overkill.

As a past Auto Technician and building cars for Subaru-Isuzu (total 20 years) I can tell you what you want to know about red and blue loctite. It can be summed up this way. If you want it to stay tight but want to be able to take it back apart use Blue. Red is considered permanent. Not to say you could not get something apart again with red loctite, but if it is a small screw or bolt you would likely round off the head or break it before the red loctite cracked loose. On guns I would recommend NEVER use red. I have never used green. Quite possibly it is a marketing ploy to keep people from running to nearly any department, auto or hardware store to buy the blue loctite.

The green Loctite is a wicking form. You use it on already assembled parts and it flows similar to penetrating oil. Strength wise it's supposed to be the same as blue.

[HuskerP7M8]

Glock recommends Loctite 648 for the "stake on" front sights(Green in color and for use on sleeves and cyclindrical parts). Most use blue or red for the "screw on" front sights. Blue can be broken free with your regular tools, but red will need heat applied for disassembly.

[GSD17]

Sights of course is what I would be using this for.

If they told us which one to use at the Armorer's course, I must have missed it. Forgot to ask as well..

[tacoprerunner]

i would only use the blue on guns. i cant think of a reason to use red or green, those are way to wuch overkill for a gun. you dont need to buy it from a gun shop its sold at hardwear stores like home depot and ace. get the big bottle, you can never have too much loctight and duct tape.

[GSD17]

Thanks.

I looked at the instructions on my GLOCK front sight crimping tool, and sure enough it does say which loctite they prefer you use.

I'll go with that.

Thanks :thumbsup:

Ok, where the heck can you buy the 648?

Having a hard time..

[GlockRik]

You can buy blue loctite at wal-mart or Lowes/Home Depot. I've used it on several sets of sights and not had any shoot loose yet. Breaks loose without heating.
Best, Rik

I have the tube in my hand right now, it says

Uncle Mikes
GUN-TIGHT
from LOCTITE
Model No. 1631

It is a blue Loctite in a green and white tube.
Hope this helps

[Batesmotel]

I found it at Uncle Miles website.

$13.00 a tube and it seems to be nothing more than loctite blue $4.49 a tube at checker auto.

[tacoprerunner]

dont get gun-tight. you can get a tube of red, blue and green for that price. if you ever want to remove the sights without damaging them use the regular blue. if you never want to remove the sights use red. i use red and blue all the time on my truck and motoercycle and the last time i took off a bolt that i used red on i had to use a impact gun to get it off.

Loctite Threadlockers-

Blue Threadlockers:

#242(Most commonly used) Removable - Used for things you may want to unscrew with minimal hassle. It cures into a brittle, glassy bond that takes one good twist to break, but removes cleanly after that.

High Temp and Oily Fastener Applications
#243(Blue)
#246(Opaque Blue)
--------------------------------------------------
Red Threadlockers:

#271(Most commonly used) High-Strength - Used on things that you don't want to take apart for a long time. It requires heat from a torch or iron (to 500° F) to loosen its grip. It cures into a thicker, sticky bond that holds up better against vibration and shocks.

High Temp,Oily Fastener and Misc Applications
#262(Red)
#266(Red-Orange)
#272(Red)
#277(Red)
--------------------------------------------------
Green Threadlockers:

#290 (Wicking)Medium Strength For Pre-Assembled Bolts Up to 1/2"; Localized Heating and Hand Tools Are Needed for Disassembly.

Misc Application
#294(Green)(Wicking)
--------------------------------------------------
Green, but not a Threadlocker:

#648 Retaining Compound High Strength/Rapid Cure. A retaining compound recommended for continuous working temperatures up to 300°F. Fills gaps up to 0.006" diameter clearance. Fixtures in 5 minutes.
-------------------------------------------------

Do your own research and don't assume I have all the answers, but this is what I recommend:

#242(Blue)-Misc screws and parts that may have a tendency to loosen when firing your weapon. Shouldn't use this for "Stake On" front sights. Some use it for the "Screw On" front sights, but I prefer using Red(#271)or (#262) if it's a "Carry" or "Competition" firearm.
I've not had a problem disassembling with Red if I use a soldering iron or heat gun(As with anything you've not done before, you may want to practice disassembly on some screws or bolts before using for your specific application).

The Green Threadlockers are not neccessarily stronger than the Red. They are just used for different apps. As shown above, they are wicking agents for allready assembled screws and nuts.

The #648(Green) is not a threadlocking compound but is recommended by Glock for the "Stake On" front sights. If you "Google" it, you will find several retailers that carry the product. I've been using an epoxy from Loctite called Black Max for this app. I think it's available at Brownells or Midway. Note the disclaimer above: Do your own research and make an informed choice.

Bear in mind you can't just specify color when discussing these products. Between Loctite, Permatex, and other companies you will find dozens of colors used for different apps. Also, they are often repackaged with a part # specific to the retailers they supply. Case in point: the "Gun-Tite" from Uncle Mikes.

Good Grief!! Why didn't somebody stop me. My fingers are sore from typing.

Blue is OK on my G23 and HIVIZ Tactical combo

GLOCK Night Sight installs has been my #1 Gun related use for Loctite. I tried 242, 262, 271, and 290. I've pretty much gone with 262 across the board and have never had a problem with it coming loose or getting it loose if I needed to.
