Anti seize (copper grease) on nuts!

[964rh]

Hi

After searching/reading god knows how many posts on this can anyone give a definitive answer to the following?
1, Do I use copper grease on both studs and around the bottom of wheel nuts? and how much?
2, How much do I put on the face of the wheel mounting?
3, What torque do I use for the wheel nuts when lubing? (some say 60%, some say 100%)
4, And what is the proper torque figure? I've been using 96 lb/ft

Thanks

Rob

Be really sparing with it or else you will get smears of grease radiating out from the nuts. I only put the tiniest amount on the studs themselves to enable the nut to spin down the thread. Keep the copaslip off the conical face of the nut and the wheel.

Hi Rob, I literally just put a smear around the studs.

2, How much do I put on the face of the wheel mounting?

Just a smear sufficent to cover the mating faces.

3, What torque do I use for the wheel nuts when lubing? (some say 60%, some say 100%)

I use 50% (75Nm) all five, then 100%.

4, And what is the proper torque figure? I've been using 96 lb/ft

130Nm

I agree with the answer given to queries 2 and 3, but not 1. You should not put any on the threads of the studs whatsoever.

Of course you should Damen -have you ever had your nuts seized????

My mech. top man @ main dealer ALWAYS puts a smear on the threads.

The article I was thinking about is in PP Jan '07 on page 68 - it actually refers to bolts on later cars, but theory is the same.
In a nutshell:

• Aluminium grease (not copper);
• Threads - yes;
• Wheel/nut contact surface - no.

The reasoning is explained in the article and makes good sense.

Spot on Alex! Many thanks. PP Jan '07 pages 68-70 refers -article by Chris Horton.

There's an issue of overtightening if copperslip (or anything else) is applied beyond where it is really needed.

I agree the smear on the threads.
The wheel nuts are alloy, the studs are steel, - steel wears alloy, copper slip reduces friction and wear, and prevents corrosion. Copperslip is a "clean" grease and safe to use around Brake components. It gathers less dirt than regular Grease in my experience.
When you feel the components, you know its right.
