When we frame walls, we normally orient the 2x4 with the thin surface facing outward.
- What are the consequences of orienting the 2x4 so that the wide surface faces outward instead?
- Does the wood have more or less strength to hold a fastener in either orientation?
- Is a 1.5" (the depth of a 2x4 when oriented with the wide surface out) embedment sufficient for a screw or nail to have maximum holding power?
- If not, what is that threshhold (minimum embedment for a nail or screw)?
- Any other considerations?
I am asking this question in a generalized format per SE best practice, but my specific goal for asking is that I want to know whether I can hang heavy things from 2x4's oriented wide surface out. The reason I want to orient them this way is because they will be fastened to concrete, and to fasten a 2x4 to concrete oriented with the thin surface outward will take a 5-6" anchor.
