Yup. My current work bench is 2x4s and a free solid core door (trimmed down) screwed together with 2 1/2” galvanized screws. It’s 14 years old now and just as solid as day one. In matter of fact, this is the 3rd home for the door as a work bench. Prior to this location it was at the last as a work bench for 8 years, I flipped it over for its new location.
