What length flat head screw to secure 3/4" thick wood to:
1. End grain.
2. Face or edge grain.
All wood is pine, not hard wood. Screw to be driven so top of head is flush with surface of wood. Shear force is not a consideration. Only withdrawing force is important. Specific project is not important as projects will vary.
I will be using Hillman bronze ceramic coated, star drive screws.
Same question for securing a 2x4 (1-1/2" x 3-1/2") to another piece of wood. What length screw for end or face grain?
