Bolts on M20 keep coming loose

even with red loctite? wow! try the green loctite suppose to be stronger...

green loctite is wicking grade. meaning it will penetrare already assembled nuts and bolts.
it does not lock stronger then red.

I would check to see that all the surfaces you are trying to lock are clean and free of all oils. use brake cleaner on the nuts and bolts then reapply the red loctite. if you are loctiting steel bolts into aluminum you should be using a primer on the aluminum
 
i dont think its simular to paint thinner. havent used paint thinner in place of brake cleaner before, and havent used brake cleaner in place of paint thinner before tho. loctite and permatex both make a surface cleaner to promote curing, and bonding. their both solvents much like brake cleaner. i dont know the number of the loctite (cant they give their products names?), but i have permatex "surface prep" and its specifically made to accelerate curing time of all anerobic sealers, which loctite is, thats why i leave the lids off my containers lol. it is also used for cold weather enviroments.
 
I am not firmiliar with the m20 bolt style, but go to stage8.com. They have some pretty awsome locking systems.....maybe one would fit your needs. ;)! I also agree with the above statment to contact FAST. I think you are missing a bushing or washeer or somthing. I can't beleive that everyone is not complaining if they design this suspension with a flaw of coming loose.

Like paint primer? The mounts are aluminum and bolts steel

no its not like paint primer.

it is a primer made by henkle/loctite specifically for bonding aluminum and other inactive metals using loctite. I do plant maintenance for a living and took a class on loctite products a few years ago, locktite explained it to me like this.
loctite is designed to bond with the absence of air and the presence of metal(Iron) its an anerobic
aluminum does not have the same components in it that steel has and inorder to get a proper bond with aluminum you need to use a primer.
I am sure many people will chime in and say that they never had a problem bonding steel with aluminum and thats fine for them. you are having problems and i suggest you try this.
if you read the info i attached it comes direct from loctite. http://www.quicktite.loctite.com/us/con ... utions.pdf
at the bottom of the threadlocking page (2) on the left hand side you will find l list of inactive metals that requier the use of primer N. aluminum is the first metal listed
good luck, hope this helps
