impact wrench

I have somewhere here a small manual that lists the effects of various lubricants on thread torques, but I can't find it this minute. Might be at work. I don't think water was listed, as its lubricity under that much pressure should be insignificant. I'll see if I can find that book and post a few figures.

Likely that the manufacturer expected clean and dry threads. Lubricating with anti-seize assures overtorquing....

...but I suspect that you need to try a quality wrench.... Matco, Mac, Snap-on.... etc...

or better yet, break them loose by hand...

I found my little book. The effect of various lubricants on torque settings looks like this:

Steel, non-plated, dry: 1.00 of torque spec. Grease with copper, graphite, and aluminum flakes: 0.85 of spec Zinc electroplate 0.85 C5A copper-graphite anti-seize 0.80 Motor Oil SAE 20 0.80 Dri-Lock adhesive coating 0.75 Zinc anti-seize 0.75 Graphite 0.70 Grease with graphite 0.65 Moly-50 anti-seize (moly disulphide) 0.65 Dri-Lock 200 0.60 Graphite and motor oil 0.55 Oil (heavy) 0.50 Moly-Cote 0.45 Never-Seize 0.45

These are just a few from a lengthy list. Be careful with that Never-Seize; using a standard torque will more than double the stress in the fastener.

How about this one

It has to be a Chinese import but it is a 1/2 drive and rated 730 ft-lbs working and 800 ft-lbs max. and is only 98 buck Canadian, that is around 85 US

If the 800 ft-lbs. is for real, you'll either break the lug nut loose of flip the car over.... and I'm really not sure which!
