Connecting the Airplane to the Bearing

How do we fasten the aircraft to the column?

One of the strongest areas in the airplane is where the wing is attached to the fuselage.  The wings and fuselage are fastened together with thousands of small fasteners and four big fasteners.  We attach the outer ring of the bearing to the two big fasteners on the left wing and to the two on the right.  The big fasteners are called spar pins.

The front and back of the wing box shown below have large pins that hold the fuselage on top of the wing.
