Dry or Lube?

[DrWazzock]

Back on topic I though all torques quoted were for “lightly oiled.” as in some light machine oil. But I use copper grease on wheel nuts, and also twitch them up after a few miles rather than muller them first go.

Righty tighty lefty loosey

Banned if you need a tub I’ve some under the counter

Plenty here thank you

Can anyone explain the difference between dry, oiled and greased nuts in terms of ugga duggas?

 

[Badshot]

If torqueing them up to a specific torque then DRY, theres a video somewhere showing a guy dry torqueing, and lubed torqueing. The lubed one strips the thread before hitting torque. If just using the good old FT torque method a bit of lube is fine if you have a good feel for it.

I have been using grease and oil for the last 50 years.

Maybe its obvious but keep a jam jar with oil an old paint brush and old toothbrush, then its ready for action.

So, all the wheels are on, little dab of copper on each nut.

How long a scaffold tube shall I use to torque them, and how many bounces for a 15 stone bloke?

Gonna need a slide rule to convert the aforementioned 15 stone bloke on 10 foot scaffold pole into ugga duggas. Unless someone knows the precise number. Then there is the small matter of whether a snap-on ugga dugga is the same as say a Milwaukee ugga dugga.

Never leave your nuts in the sun

When a bolt is lubricated - less torque is required to achieve bolt axial load or tension. Reduction of torques for lubricated vs. dry bolts are indicated in the table below.

Lubricant	Torque Reduction (%)
Graphite	50 - 55
White Grease	35 - 45
SAE 30 oil	35 - 45
SAE 40 oil	30 - 40
No lube	0

On the other hand, according to data collected and analyzed by Shigley and Mischke, there is not a correlation to an average difference in torque to tension of dry vs. lubricated fasteners. What the data indicated was that lubed fasteners acheive a desired preload at a much more consistent torque value. Applied torques on "Dry" fasteners on average yield roughly the same preload, but there is a much greater deviation from that mean or average value from dry fastener to dry fastener vs. lubed fastener to lubed fastener. If you are looking to control preload in fasteners to a tighter range, then lubricating them prior to torque will give more predictable results, not higher values compared to dry conditions - according to Shigley and Mischke. https://www.eng-tips.com/viewthread.cfm?qid=173061

Manufacturers, engineers and other industry experts seem to unanimously oppose using lubrication. On the other hand, some DIYers and self-appointed Internet forum experts claim to have used thread lube since the very dawn of time with nary a problem.

Once spent an enjoyable afternoon on a motorway sliproad helping a tyre fitting mate balance on a scaffold pole to undo truck wheelnuts. Took him about 6 bounces to undo so maybe 3 to tighten?

the danger ,as already correctly mentioned in 2 or 3posts above is that grease/lubricant will make it easy to over tighten them , definitely doesnt help a torque wrench to click off where it should do.

spot of oil from on the stud thread from the oil can is a compromise to prevent corrosion but still take care when tightening.

because they will be checked shortly after or during first using for tightness see they aren't running back, wont they.
Copper grease is apparently not very healthy for you when it dries out and dusts or flakes and /or are potentially ingested is the theory as well.

edit "sounds like 15 stone bloke needs to stop with the pies ,does depend on how tall he is tho .lol."

 

[Tractorstant]

should check your nuts daily!

 

[Will 1594]

Use ally slip here or copper ,like ally stuff better ,
always give wheel nuts a dab with paint brush ,of ally slip ,or a squirt of oil ,

 

[Bob lincs]

We give the studs a blast of WD40 or similar product .

I astonished @Bald Rick is so late on the scene with such a thread title...is he unwell?

 

[organicguy]

One instruction manual I have seen gave separate torque settings for oiled and un oiled.
Always apply some form of lube to wheels nuts or anything else I think I might have to take apart again.

He'll be outside scaring the birds away.
