This is a picture of one of the SORAC project hybrid motors
showing a high strength bolt circle. It used 3 rows of ~50 screws
per row to achieve the desired holding/clamping capacity.

These screws were originally manufactured for the latest Airbus 380
but, much to Dave G's chagrin, a teeny tiny flaw in the finishing process
caused them to be rejected. The flaw was only superficial but them finicky
Frenchy's tossed the whole lot.

Dave is not on this airplane - but his screws are!
