All my working life I have encountered people that were either mechanically inclined or not. The latter group, in my experience, more often than not think tighter is better. They'll apply the gorilla grip to any
threaded connection of any sort.
The more mechanically inclined will be knowledgeable and/or intuitive enough to apply only the torque needed to accomplish the task at hand. The more mechanically inclined person will exercise care to avoid cross
threading knowing full well what that can lead to. They will exercise even more care when the
threads are known to be fragile.
If a topper doesn't make electrical contact with a pv there's a reason. The solution is many if not most times
not lack of torque in the mechanical connection.
But the less mechanically inclined will always continue to muddle along and blame the device rather than their own ineptitude and impatience.
