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?
cheers
Bob
Bob, I heard you the first time.
Do you know what the number (lbs) is, since you ran the tests?

depends on the loading conditions & assembly
an ultimate number or an allowable (like a working load) number?
allowable in timber like ~100lbs
ultimate load in timber, probably 400lbs
ultimate load in a test machine...depending on the steel
condition / alloy; maybe 800+ lbs
cheers
