I'm not sure how much I'd trust your hitch pin for a yanking situation. A tow strap looped over your hitch pin will provide a "point loading" of your hitch pin roughly in the middle of the pin. This makes the pin support the weight by not bending in the middle.
A pin supporting a a 2" receiver and shackle will only be loaded by shear forces right at the point between your hitch and the receiver, this is what these pins are designed for.
Crude ASCII sketch below:
Ignore the periods they are required for spacing.
Point Loading
.|...|...|
.|...V...|
.|-----|-
.|.......|
Pin tries to bend in middle.
Shear Loading
.||......||
.|V.....V|
.|------|-
.|.........|
Pin isn't subjected to any bending.
Variable space text makes it difficult but use your imagination.
