Scot,

Finally into the office this morning and found my modern timber engineering book to come up with the proper term for the question you asked.

Based on what I found there it's the increase in bearing area below the fastener which is probably behind that requirement.

Pretty amazing that a 65 year old structural design book has all that relevant information.

fasteners for sway bracing

for loads perpendicular to the structural member
 why should the fastener be installed a minimum
 1/2 the depth?  Is the structural member stronger
 on the upper half?
 Is the ceiling/roof load restrainin' the upper half of the structural
member,
 although it is not a given...?

 in my brain, i don´t know what is happenin...

I should not have slept during the lectures on Mohr´s circle...
