Fastener question

[estley]

I'm building a Yoga wall for my wife. It's basically some custom brackets, inset into a 3/4 sheet of plywood, hung on the wall. I screwed 4 rows of 2*4s to the wall where the sheets of ply will hang.

Since this wall will have a fair amount of load applied to it, in more than one direction, what kind/how many fasteners should I be using to hang the ply to the 2*4 grid?

for reference, at the bottom of the page you can see pictures of how the wall is actually used and the directions it is pulled in:

I'd be more concerned with anchoring the grid appropriately to the framing members behind, and for that, I'd use GRK RSS screws.  I'd use the GRK R4 screws, and plenty of them, to attach the plywood to the grid.  YMMV...

sounds pretty much like what i was planning on doing, for the plywood-to-grid, i'm thinking 12 #10 by sheet, 3 columns, 4 rows

I'd go with 3 columns, 7 rows, presuming 24" OC studs.  If you're using 16" OC studding (a better choice), go with 4 columns, 7 rows.  Be sure that the eyebolts are screwed into the grid, not just the sheeting.  Screws are cheap.  Accidents are far from it.  Just my opinion, YMMV...

i do have 16"OC, and we're not using eye bolts, they're steel plates that sandwich the ply...
