Actually nominal 2 inch lumber has thickness of 1.5" [1].
So your screws should be shorter than 1.5".

- TeMPOraL 9y ago> Actually nominal 2 inch lumber has thickness of 1.5" And, as I've recently learned, two-by-four is in fact 1½ × 3½ inches. How on Earth does that make sense? Why do people call things as if they were X, while knowing perfectly well they're not X? Is this an American thing?
- wetmore 9y ago2x4 lumber is cut into rough boards in the milling process which are actually 2 by 4. These are dried (at which point they shrink) and planed (the wood will warp a bit during the drying process, jointing and planing will help correct this) so the resulting boards are smaller than their original 2x4 size. Some more surprising detail in reality :)
- TeMPOraL 9y agoHeh. I feel that reality is just that beautiful, never-ending fractal of annoyance...
- atrus 9y ago2x4 are 2x4 when they are rough cut. The ones you buy at a hardware store have been jointed/planed to the 1.5x3.5in size.
