Can not use the 7075 due to lack of sleeve availability.. So:
Thanking you in advance for your feedback.
Should there be concern for a heat treat hex head 4-40 bolt inserted through both sides of a 1/2 inch c/f tube at right angle which is the control arm for half a flying stab on a plane anticipated to have an air speed of 70~75 mph?
Tube is located at 25% of the stab MAC. Lock nuts are on each side of 4-40 bolt where it passes through C/F tube. Is there concern for bolt threads enlarging the drilled hole? Do I need to sleeve bolt or use a 1/2 inch shanked bolt?
