Grease on bolts

When ever I do something on my Ranger that requires a bolt removed I always put marine grease on the bolt when I put it back.

Never had one fall out but it has on multiple occasions been a blessing when years down the track I have had to undo them again.

Only took 2 years to reply but RossPat and i are going nowhere in a hurry any way :)

I love listening to this guy when I have no speakers on my PC.

Nickel grade anti seize is good stuff but if you really want to treat yourself get the loctite silver grade stuff, I’m a fitter by trade and I’ve never had a nut or bolt seize on me after using the silver grade. Beware though, we call it travelling grease in the industry because one tiny blob on your hand and before you know it, it’s bloody all over you!

That's the only time to "listen" to him

I've always used a mere smudge of copper based anti-seize paste on all bolts and especially when its a stainless steel bolt to a stainless steel Nyloc nut

Whats your view on wheel lug nuts ? The manual says not to lubricate them and to do them up dry to 139 Nm torque but I've always just applied just the merest smudge of copper anti-seize on mine. I guess the reasoning behind doing them up dry is that if they are over greased the pressed-in stud can be snapped off due to excessive torque that you get by clueless idiots doing tyre and wheel changes with air powered ratchet guns with the incorrect torque setting for the lug nut size.

There is a formula for the reduction in tightening torque when applying anti seize grease to bolts.
If I recall correctly the reduction worked out to about 30% for the wheel nuts.
I add a smidgen of copper slip to my wheel studs and reduce tightening torque to 100Nm.

I'll see if i have the document. It was referred to by John Cadogan in the above video from Ajax Fasteners so not a thumb suck guesstimate.

I would be interested to read that formulae -- post it if you can or at least if you are able to give us a reference to it

The link to the document in John Cadogan's video:

If you go through the video he does reference the page and show it.

I read the relevant page and listened to the video but just how much anti-seize does one use ? What is a smudge to one man could be a total smear to another.
Ahh to be or not to be, that is the question !

From the document:

How Much Lubricant Should You Use?

Proper lubrication means that you’ve put lubricant on every thread so that the valley of the stud is full.

Notice how we lubricate enough so that when you hand rotate the nut down, there’s a little bead of lube that squishes out. This means that we’ve put lubricant on all the parts that will experience friction when we apply torque.

I don't apply quite soo much. I feel that a thin film across the threads is good enough.
The peak and valleys all have copper slip on so all parts are covered.

I found that with the (even a little) bit of lube that squishes out - with the heat from the brakes this would then run (melt) and spread out ( from the centrifugal forces) from the all wheelnut locations.
Makes a bit of a mess. Not major - just not clean

As I said, this lubrication of lug nuts is a real doozy, just how much lube does one use ? The 30% reduction in applied torque is you do lubricate to me seems an excessive reduction and its based on a presumed amount that is applied and the type of lubricant isn't mentioned or specified.

For my part I only use the merest amount, using a copper anti-seize grease and applied with a cotton bud mainly to the taper on the lug nut and even less to the internal tread.
I'm always aware of the Ford - and other makes - requirement and specification that the required torque should be applied DRY and that no lube should be applied.
Oddly enough when I worked at Aston Martin Lagonda a lubricant was recommended as they had wire spoked wheels and the wheel stubs had splines with knock on wheel nuts, and like some Chrysler models the RH side nuts had counter-clockwise threads !!!
Years ago when you could easily buy them at a corner store I just used a domestic wax candle rubbing it lightly inside the thread of the lug nut, the small amount of wax in the threads was quite enough to prevent the nut seizing onto the stud.
