Bolt Circle 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!
