#10-32 bolts will be used exclusively. The fastener spreadsheet shows how many of these bolts will be used to hold each component together. These bolts are of a larger size than needed and used in far larger number than required for the size and mass of the spacecraft, to ensure a high factor of safety. More discussion can be found on the fastener analysis page.
