This company is the leader in producing the 5/16" face-nailed (or top-nailed) oak flooring.

click on the 5/16" link, then click on the installation instructions near the top. This floor type is not for the DIYer. It requires a knowledge and skill, plus the proper tools; and the nailing is essential for proper performance. Lowe's and Home Depot don't sell this kind of flooring, only certain flooring distributors do. If you want this type of floor, I recommend hiring a very experienced flooring installer well versed in this exact type of flooring. I have laid many thousands of feet of it in the SF Bay area in my 25+ yrs. working here. I'm one of the very few who still use the Cavanaugh nailer to install it.
