Thread locker equivalent

As I unbolted my axle from the transmission this week I noticed the same Blue/Green or Cyan colored thread locker Porsche uses on bolts throughout the car...does anyone know the Locktite equivalent ?

I noticed the factory specs for those bolts is 60 ft pounds....it sure took a lot more than that to get them out....but I sure do not want them backing out on me

I am far from an expert but I would use Loctite 242 which is blue in color and semi-permanent meaning it is designed to be removed.

Some what easier to use is Permatex 09978 a gel stays where you put it no drips.

The loctite also comes in a big tube like a giant chapstick, very easy to apply and also stays where you put it. I got that and also an anti-seize tube as well. Less messy.

Breaking torque is higher than running torque because static friction is higher than dynamic friction. There may have been corrosion contributing to a higher breaking torque as well.

Blue is always my go to for firearms and Medical equipment I maintain...so I will stick with that......I know Green is some serious permanente stuff.

I've got both a 986 and a 987, and there are very few places the factory uses thread lock. I have not seen any thread lock on the axle bolts for either of my cars, or on the replacement bolts purchased from Porsche. Are you sure you aren't confusing the anti-corrosion coating of the bolts with thread lock?

Having said that, if you want to add thread lock I would not use anything stronger than blue.


As a followup, here is an example of the axle bolt sold by pelican for a 987 http://www.pelicanparts.com/catalog/SuperCat/1087/POR_1087_SUSAXL_pg1.htm#item0
Note that the entire fastener has a greenish tint to it. Also note that the item description does not mention any thread lock.

Here is an example of a bolt with micro-encapsulated locker on it: http://www.pelicanparts.com/catalog/SuperCat/1042/POR_1042_ENGCAM_pg3.htm#item6
note that the material is deposited only on a portion of the threads and is typically a contrasting color to the rest of the fastener.

My links didn't work very well. First example is the 'axle joint bolt' that is OEM equivalent. Second item is Porsche 'bolt for intermediate shaft flange'.

Thanks Spendy

THis is exactly what I am seeing on the inner bolts of the half axle ....of course I am not the original owner.....so all I have to go on is what I find when I take it apart. Many of the fasteners we use at work have the same pre coated locker on them so I am used to looking ta it.....and Blue is removable without heat so it cannot hurt.

And the thread locker doing it's job.

Loctite is my go-to stuff, but I also rarely use thread locker *shrug*

Porsche recommends replacing the bolts every time also. They are 10.9 grade so I just replace every other time with blue loctite every time. Don't forget to clean the grease out of the threads & the half-shafts where the bolts pass thru.

BYD - great advice thanks.
To expand - he means "chase" the threads in blind holes. But you don't have a thread chaser? But you can make one if you sacrifice one of the old bolts or use a lower grade bolt with the same thread pitch/diam. Make 2 or 3 spiral cuts along the length of the thread of the chaser-bolt. Dip it in solvent and ease it down the threads.Remove frequently to add more solvent to the chaser. Dry with compressed air or a heat gun.
You can buy great 10.9 bolt assortments on EBay in JIS+washer head or Allen head style.Add your own oiled washer / Loctite appropriate to the situation. Just as good as an OEM MEC bolt of the same grade imho.
