Torque Wrench > Useful Torque Range??

Interesting.

If doing offroad/adventure riding work then torque values, torque wrenches etc are all workshop clutter that isn't being carried.

What I normally do is torque to the required value, mark with a sharpie/pencil/ blood or whatever, then undo.
With the use of a hand/foot/ running jump, match the lines up.

Abracadabra, the nut is now, in reality, somewhere near the desk intended target

 

What a simple solution for work in the field. Excellent.

 

That’s a pretty accurate way of getting the correct torque out “in the field”, plus, it helps on things like rear axle nuts where you have to line up a castle nut with a hole in the axle for a split pin or R clip.

 

I would expect the FSM to have info regarding lube or thread lock in addition to torque settings. The only lube I’ve ever used on spark plugs is a dab of copper slip but that was on a cast iron head. Never use any wet lube like oil or grease as it’ll just carbonise near the tip with the heat and can hinder removal. I like to use some anti seize on any steel bolts into alloy, especially if they’re exposed to water.

 

Have a look at this.

 

Also both the fastener material and substrate material both need to be considered. I.e. don’t torque for SS when you are screwing into ally.

 

I thought it was just thread it on and nick it up! Torque wrench? Never used one, even when I helped out in my Dad's repair shop!!

 

It is, don’t over think it. That’s what the torque specs are there for, worked out by the manufacturer so you don’t have to.

 

Try searching for “dry vs wet torque values” basically any liquid will lubricate a thread such that the same clamping force can be achieved but with less torque.

How much less depends on how good a lubricant the liquid is. You will find a range of answers, generally in the 20-30% range.

The “lubricants” that you will be using will largely be for one of two purposes. To make it easier to undo at a later stage or conversely to make it more difficult to undo at a later stage.

I meant to include this cartoon!
