Can anyone help me find allowable pull-out values for a 1/2"
diameter stainless steel bolt in a tapped hole in 6061-T6 aluminum as
a function of embedment (thread engagement) length, from 1/2" to
1-1/4" deep?  Nothing in the 1994 UBC looks applicable, as regards
stripping the aluminum threads.

Thanks much,
