What benefit does putting screws through the door jambs offer?
In a word…strength. Pneumatic finish nailers are great, but they don’t provide for much structural strength. We use flat spacers at each hinge and at the strike plate, then we put a screw right through the jamb into the wall stud. Not only does this help initially secure the door in place, but helps deter future movement (whether from moisture loss or overly energetic children).
