Thread Locker: Blue V. Red

[built2bashranger]

If the thread lock is gold, it's as permanent as it gets. Gold also will lock an already assembled bolt & nut. I've seen a 1 inch bolt gold locked that had to be torched off.

naaahh jb weld is the stronger better yet a good beas of weld works good to

Refering to Loctite by color would get you into Deep trouble in my shop.

As I have two kinds of red three different kinds of "blue", three different
kinds of Green and one that is actually purple.

And the three kinds of green are for completely different applications.

There's the RC680 which is intended for gluing bearing races into place.

Another kind usually sold as "Wick 'N Lock" is a super fluid type that will
actually wick into assembled fasteners. (this was green years ago but
nothing prevents them from changing the color, it's only a dye)

the funny thing is that it was actually originally developed as a porosity
sealant for aluminum castings in the aircraft industry.

I actually had access to enough of it at one place I worked
that I was able to "vacuum soak" a pair of virgin aluminum
cylinder head castings for several days (including several helium
flush cycles) then have them submerged in a tank of Loctite porosity
sealant when the vacuum was collapased... I still have those heads.

When I say "blue" I'm usually refering to 240 or 242
"red" generally refers to 262 or 271
"Green" usually RC680, though I have a big bottle of RC609 too.

the "purple" is (I forget the number) is specifically for small fasteners
And when I say "small" I mean REALLY small, 4-40, 2-56 or 0-80 screws

In a lot of applications I avoid using locking compounds by installing
prevailing torque threads, usually by installing helicoils with their "Locking coils"
