Having trouble finding this answer.. Which countersink do I need for the #10 screws on the rudder? Is it 82 degrees, or a 100 degree rivet countersink? On that note, what would the 130/120 countersink so be needed for?
Thanks! I was lookin in the manual before I ordered a countersink. Yard store has like 4 different degrees of the same countersink. I appreciate the help"AN" solid rivets and "AN" screws have 100? heads.
Pulled rivets typically have 120? heads.
Non-aircraft screws typically have 82? heads.
