My local code list 3/8 or 1/2 inch OSB on 16" OC studs for exterior walls. I am ready to hang 7/16" OSB thinking it falls in-between the sizes listed somewhat. Before I put nail to OSB, would 7/16" work? I am in Virginia, my county goes by state code. Thanks for any advice.

Thanks! I did look for 1/2", and like you said, hard to find. Was thinking of beefing up to 19/32" but couldn't beat the price on 7/16".

I appreciate the confirmation on using 7/16. I started hanging it today.
