Can you screw into the end of a 2×4?

Because wood is relatively weak perpendicular to its grain, screws don’t hold that well when screwed into the end grain. Wood screws do, however, hold extremely well in cross grain. So the trick to making screws really hold in the end of a piece of wood is to give them a bit of cross-grained wood to bite into.
