There are many anti-seize compounds out there not only Copper Slip, but this should not be used on aluminium alloys, from left to right I use Copper Slip for steel to steel, secondly Aluminium graphite on Steel to steel, steel to Aluminium and most thing on motorbikes,
to the right we have the crème de la crème when it comes to anti-seize, ceramic grease this can be used on all things steel or alloy and also on brake callipers.
Steviejuk I agree with the second part of your statement,
An now we will have the boys on the side saying once again that, anti-seize compound will affect your torque setting, the calculations for working this out exactly are mind boggling for each type of lubricant.
So if you have a brand new digital or freshly calibrated linear torque wrench and would like to work it out, then on average the friction loss by using a lubricant on the threads of a bolt is about 25%, now this is where it gets interesting, you only put the lubricant on the threads, so take a look at the diagram below and this will explain how to work out the reduction for your torque setting,
Now divide the 40% by 4 to get your 25% of reduced torque.
lets say we have a bolt with a setting of 100Nm
That’s 50% flange face friction 10% bolt stretch friction and 40% thread friction.
40%=40Nm/4=25% thread friction =10Nm torque reduction.
Someone correct me if I am wrong but with most snap type or old torque wrench tools, they are more than 10% out on calibration before even getting them out of your tool box,
So if you don’t have a brand new or freshly calibrated linear torque wrench and don’t clean off the threads on each bolt as well as the threads the bolt is going into, each time you refit them,
THEN JUST PUT SOME ANTI-SEIZE ON THE THREADS and the jobs done.
