Bolt size rear diff cover on 3500 dually with 12 inch ring gear

[CdnHO]

Anyone know the bolt size for the cover on 12 inch diff on 2021 3500 dually? Did a search but no joy. One fell out of the banks cover and I need a temporary replacement. If I recall they are held in by thread locker, so I probably used too little. Thanks folks.

That sounds weird. I would check the rest just to make sure maybe somebody stole one. They didn’t feel like waiting either.
