Default airplane construction

Without the strut, which is in tension during normal flight
and compression when at less than zero G, the wing would
just flap up and down.

The close fit of the bolts in shear is required so that
loads are transferred evenly to the structure.The torque on
the shear bolts is minimal and the nut just serves to keep
the bolt from falling off/out.
A bolt in tension is torqued so that the bolt is loaded into
the elastic range and the tight bolt is stretched very
slightly and then, as long as the bolt stays tight, it does
not accumulate stress until the loads exceed the elastic
limit.

| Cessna uses a bolt installed in shear through fittings
like

as

hold
