And once the threads have been contaminated with ,say grease from the handlers hands, that 3.5Nm could well be equivalent to 5 or 6Nm dry.
The use of torque, especially via a crude tool like a torque wrench is a nonsense.
Possibly a bit harsh given that it works well enough in many industries such as automotive etc. If something is really that critical youâd be using something else such as a hydraulic jack, but tightening a screw on a speaker cabinet using such equipment would be somewhat tricky, not to mention overkill.

Agree that itâs the only practical solution in many cases, but just need to recognise it is not a precise measure of bolt tension, which is what you are trying to achieve. Hence why the discussion about whether something os 3.5 or 3.7Nm makes little sence.
There has to a number to set it to by the manufacturer.
To try and make it idiot proof and if done by a competent dealer then there should be no problem.
Anyone doing anything else is at their own risk.
Do you argue with the manufacturer that tells you the torque setting for your car wheel nuts or anything else.
There has to be a figure somewhere.
Even Linn agree that âLinn Tight â is history.

I agree the manufacturer should disclose specifications, that doesnât bother me, but it doesnât stop me from finding the setting that works best in my build. The risk of someone else being sloppy is not one Iâm willing to take.
As for competent dealers, thatâs a construct I donât recognize. Even if Hamish Robertson himself were to resurrect and configure my turntable, I would still take it apart to verify that everything is as it should be.
In the automotive and aeronautical industriesâŚ, depending on safety and usage, there are torque standards.
Torque settings are also useful when certain materials are susceptible to breaking during vigorous manual tightening.
The Karousel is a robust part that does not pose a major risk of breakage, however if Linn specifies a preferred torque of 3.5 Mn, it is probably to set a benchmark for all installers, Linn dealers and competent owners who carry out the work themselves. The main thing is that the LP12 continues to produce its improved magic after the new upgrade.

Experience is a wonderful thing but I think that the reality is in this case, Linns published figures are more to protect the threads than optimise sound quality. Better to say something safe than nothing at all. The experience of people on this forum is therefore more than interesting.
