Again belleville washers are no exception.
Silicon bronze hardware is not lubricated.
Tightening torque values are calculated from the formula t kdp where t tightening torque.
Flat loading a belleville disc spring helps to ensure that bolts do not loosen while machinery is in use.
This notation is needed for load calculations if n of springs in a stack then.
The belleville washer can then be added seamlessly and no modification to this torque value is needed.

A belleville washer also known as a coned disc spring conical spring washer disc spring belleville spring or cupped spring washer is a conical shell which can be loaded along its axis either statically or dynamically.
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.
So that the bolt and belleville washers work together make sure the torque for your belleville washers matches that of your bolts.
Clamp load lb is calculated by arbitrarily assuming.
Clamp load is also known as preload or initial load in tension on bolt.
If you exceed a locking washer s torque by more than a few percent during assembly you destroy the locking washer.
