How long should screws be for 2×4?
Originally Answered: What size screw to use for 2×4? A 2×4 is 1-1/2 inches x 3-1/2 inches. If you’re joining them face to face, that’s 3 inches thick. A 3 inch long construction screw is ideal, but if you sink the screw head below the surface too far, the tip will blow out the other side.
How deep do screws need to go?
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge.
Do you need to pre drill 2×4?
It’s not absolutely necessary, but to get a good square (as in perpendicular to the drill surface) hole, fit and proper tightness, it’s advisable to pre-drill. Use a smaller drill than the minor diameter of the screw.
