Yes, bolts help so that stress not on connector. That connector on CM4 is suitable for the shock and vibe environments. That connector family is TRL9. Low risk. Qual levels are stated on product sheet and webpage. Qual reports under NDA only to qualified customers. Having said that, enjoy reading MIL-STD-810 and what the tests mean. Carrier board custom for product, but standard design approach. Entire design approach and some subassemblies and parts of it are TRL9. CM4108032 does not have the SD option (no lines active on the CM4 board to board). Only CM4lite does that. Increased storage is via add on miniPCIe in expansion ring. This is TRL9. MicroSD is TRL7 but not a great trade-off due to many issues and risk. Not supported.
