Mezzanine fastening hardware

For mechanical fastening of the mezzanine card to the carrier board, the Ethernet FMC comes with 2x hex standoffs. We highly recommend using the machine screws on each of these standoffs to fix the mezzanine card to the carrier board. If the fastening screws are misplaced, they can be replaced by the ones listed below, or equivalents.

The hex standoff and machine screw part numbers are listed below:
