Explain Loc-Tite(s)

[ExNavyInHouston]

Could someone please take a moment and explain the differnet most common Loc-Tites.

I hear about red and blue and I would like someone to explain the characteristics and examples of how you use them on Glocks.

Mainly, I want to know which one is designed to firm up the threads, but still you can unscrew if you need to? I just don't want to use the product and it be permanent.

Thanks

Try Loctite's (http://www.loctite.com) web site for detailed information. There is a product selector guide (http://www.loctite.com/selector/), a FAQ (http://www.loctite.com/selector/faqs.html), and an on-line catalog (http://www.loctite.com/catalog/).

From their FAQ: "...With threadlockers, colors designate strength. Generally red means high strength and blue means moderate strength, and purple is low strength..."

262 is red and is considered "permanent", but can be removed with the application of temperatures above 325°F (covered in the FAQ). 262 is recommended for fastners up to 3/4".

222, 242, 243, 246 and 294 are removable and have slightly different applications. Look here (http://www.loctite.com/catalog/category1.html?ProductLine=1010++++++++++++++++) for details.

I've used 262 to install a base for an Optima on my M35, and was able to remove it by gently heating with a propane torch. No damage to the finish. IIRC, blue 243 is recommended for front site installations.

I use 242 (blue) for scope mounting screws. I use red (271) Loctite for installing front sights on Glocks. I use green (640) Loctite for installing muzzle brakes on AR's.

I've removed several front sights that I'd installed with 271 Loctite. I've never had to apply heat to remove the screw. With larger screws, that might not be the case.

I've always been intrigued by loctite. They make some that's used to glue the nose cone to intercontinental ballistic missles. I wouldn't mind having some of that to seize up by friends lug nuts as a practical joke..:)

Thanks for the input ... one last question.

Which Loc-Tite would you use for non-captured guide-rods? The type that requires a small screw at one end. I have read that some folks have a problem with the screw backing out after repeated firings.

I yet to set a guide rod like this, but I was considering a metal version for my 19 & 30, but on my Kel-Tec 32 there is no screw. The spring itself fits flush against the Recoil Spring Catch.

Not knowing how an aftermarket Glock guiderod works this may just be another one of those questions that identifies just how little I know. hehe!

I'd use the blue (242) Loctite for the guide rod screw.
