How do you reach that astounding conclusion in general?

The relative strength of a nail and a screw will depend on their
relative sizes and the material of which each is made and has
little, if anything, to do w/ the difference between simply being a
nail or screw...

How?

Drive a common 16d nail 2/3 into a 2x4.
Do the same with a common screw of the same diameter shaft.

Take sledge hammer and swing it directly down on the nail. *It will
bend. Do the same to the screw. *It will "shear" right off.

You're confusing impact strength with shear strength.

I'm not. *It relates enough to get the point across.

I've seen the tests, I've sat through the lectures.

Mike-

If these tests & lectures were involved in process that lead to a
technical degree (physics or engineering)....please let me know so I
can notify your alma mater to begin the "degree recall process".

You have, in the later part of this thread, violated "the first rule
of holes"..........which is "stop digging".

shear & impact tests are used to determine different properties....

btw find that 16,000 lb number yet?
