Why would you use Disc Springs on your bolts ?

Disc Springs ensure you have a constant load on your flange, this is important because the preload on a bolt will relax resulting in  reduced  force on the flange that may lead to gasket failure.

Thermal cycling or changes in temperature cause metal to expand and contract also reducing the ability of the bolt to maintain a load on the flange . 

Applications with increased vibration will fatigue and damage flanges without sufficient dampening  that Disc springs can provide.
