3/4" long wood screw
3/4" long wood screw
(OP)
we are going to build a steel stud partition wall in an existing building. the top of stud will be connected to the 3/4" OSB roof theathing with a slip clip.
we can not penetrate the roof. So I am looking for some
3/4" long wood screws. it seems they have #6x3/4", #8x3/4" but I can not find any capacity (shear) of such screws to osb, any suggestions? thank you.

In the past, I've gone through the yield mode equations of the NDS assuming the lowest grade of wood used in the plywood. I had to do a little searching to find out what that wood was, but.......

You'll have to register. The dowel bearing strength I mention is on page 16. It looks like you can use that in the yield limit equations of the NDS to come up with values.

Nice find. I didn't see that. Interestingly, the values are identical to the APA's Panel Design Spec.

There has to be a better way.
Put some blocking between whatever roof members are there supporting the OSB, than attach the wall to the blocking.
