Loctite types. Added chart PDF link in OP

Post by Tycer »

Chart PDF from Henkel http://www.henkelna.com/us/content_data ... _Guide.pdf

Source: http://rc.runryder.com/helicopter/t642764p1/

271, Red: High strength threadlocker for larger diameter hardware.
262, Red: High strength threadlocker for for hardware smaller than that which uses 271 (more like heli parts). Either does a good job for our stuff, however. I see 271 most commonly in auto parts stores.
609, Green: Retaining compound, high strength, for mounting slip fit bearings to shafts. An appropriate product for tail boxes.
603, Green: Retaining compound, high strength, similar to 609 but good where the parts may be a little oily. Good for mounting oilite bushings in housings, BTW.
640: Green: Retaining compound, high strength. Similar to 609 and 603. Lacks the oil tolerance of 603. I use it where I might have trouble with adjacent bearing contamination with the product, such as start shaft bearing blocks, since it has a little greater viscosity than 603.
638, Green, rather thick: Ultra strong retaining compound for assemblies with a marked amount of slop in the fit, min 0.004". Don't try to use this stuff for our normal bearings on healthy shafts. It sets almost immediately in the tight gap, and you'll never have the chance to get the bearing into place.
290, Green: Wicking product for thread locking AFTER assembly. Medium strength, much stronger than 242 blue in my experience. Not the correct choice per loctite for bearing mounting.
242, 243 Blue: Classic medium strength threadlocker for most of our threadlocking applications. 243 is the oil tolerant version.
222MS, Purple: Low strength threadlocker for small diameter or otherwise delicate fasteners.
Bottom line:
NEVER choose a loctite product by color alone.

And never use the red loctite that some scope mount/ring & iron sight manufacturers include with their product. :evil:

I used the red that came with my XS ghost rings rear, much to my disgust when I tried to remove it.

how about an OT recommendation for me?
rudder bolts in well nuts on my kayak, 1/4-20, vibrate loose on the highway with Blue loctite
thanks

(and I have tiny M5 bicycle bolts in sloppy worn lugs seated in Blue that after many rough miles stick like they're wearing locknuts)

271 red. They'll require a bit of heat to remove and won't vibrate loose.

Told you that " put some blue loctite was not a viable solution," too many variables.

bulldog,

my choice for small machine screws in a high vibration environment: lots of blue stuff and a double nut.

Cheers,

Tycer, thanks again for this thread.
I copied you to a permanent Mechanical Bits thread on the Classic (fly) Reels board
Hope that's OK

Purple is great when you want to be able to adjust the screw and have it remain stuck after adjustment. I have used it on the opposing windage screws on a Mini 14 that would walk loose in short order. They are now adjustable and I do not have to reapply after adjustment. Not that it matters, but I used the Permatex brand, since that was available locally at O'Reilly auto parts.
