Belleville Washer Experiences?
Belleville Washer Experiences?
(OP)
What types of applications have you successfully and not successfully used Belleville washers?
I have an application where multiple M20 grade 10.9 capscrews are used to hold a cover on a housing. The external loading into the cover sometimes is high enough to cause the cover to slip eventually causing the capscrews to loosen. Would a Belleville washer(s) provide any benefit?
Thanks for your comments!

Without more information it sounds as you either don’t have enough preload or you need a higher strength fastener. A disc spring will not substitute for the proper strength fastener tightened to the proper preload.
If you can come back with more details of the connection like loads, no of bolts, torque values, etc.

Think about your joint design with a coil spring where you are planing to use a Belleville washer. Does it seem ridiculous? If so then it is clearly not a good application for a Belleville either.
