Bolt grease question

[KenO]

There is another thread on this, not sure where, but someone had a problem with galling of the lugs. Someone knowledgeable about lubes posted to use engine assembly grease.

I bought a tube at an auto parts store. It is lithium based with molly, and black, for extreme pressure, and high temperature. Says its for coating cams, cranks etc after assembly to prevent galling during start-up and break-in.

I haven't used it yet, I have used Hoppes gun grease with no problem.

If you live in California, you might not be able to use it, it says California has found it to cause cancer and birth defects. I figure I'm OK, don't plan on eating it. (just a stab at some bad humor.)

Don't know for sure, but I think that it is "known by the state of California" that just about every substance known to mankind causes cancer, birth deffects, dengue fever and leprosy.

I've been using DuPont Teflon Multi-Use Lube for a while now with no problem. A friend of mine tried it and did not like it. Anyone else use it?

i like to roll my own. read about automotive ep(extreme pressure) grease and gave it a try...too thick, so i added just the right amount of kroil and have a grease that stay put and allows my bolts to glide like their on air.

Actually used DURING assembly. GM assembly lube was excellent also providing lubrication for the crucial moments prior to the oil pressure arrived however I found it to be superb when a completed engine was to be stored for some time until installed. Clean lugs and action with an anti-galling lube has worked flawlessly for me. Stainless steel loves to gall so it is particularly important when working with it to clean and lube.

Super lube is not recommended for low speed high pressure applications like bolt lug lube according to their web page. I use neco moly slide now.

I use what the patriots and early settlers used, a concoction consisting of whale oil, bear grease and beeswax. It was good enough for them and it still does the job today. Non toxic and no carcinogens too. ;D

I can tell you GM neglects to add lube to their front wheel bearings! LOL Replaced my driver side at 20K and the passenger side at 40K

Where are y'all applying the lube? All I do is on lugs and where the cocking piece moves on the bolt body. Firing pin spring and pin is lubed.

That wasn't GM. It was the supplier they squeezed the last nickel from and it was a nickel's worth of grease.

And the primary extraction bearing surface on the bolt handle.

I use White Lithium. I'm not worried about how long it lasts cuz I'm gonna clean it off and put on a new coat next time I clean the rifle; that's every time it goes to the range and as long as it lasts through one shooting event a thin coating of any good quality great will work just fine.

If you consider all the moving parts in an automobile engine and the fact that they are put away wet and started up dry thousands of times before any usual hard parts break, I'd say a good motor oil could be used to lube anything.
