The door is wooden, but the door frame is metal (I found out when the screw wouldnt go in no matter how I hammered it). Is there a way to install a hasp to put padlock on? (Are there screw drivers for metal surfaces?) Or is there any other way to have the door locked without having to installing a cylinder lock?
You need to drill a hole first with a metal twist drill bit. Get a drill bit that is the same size as the screw shank (the solid part below the threads - the hole must be smaller than the diameter of the threads, so there is material for the threads to bite into), mark the location of the holes for the hasp on the frame, and drill the holes to the depth of the screws. Then attach the hasp.
=== you really need to drill with a small hole bit for the screws that can hold the part of the hasp in the metal door jamb ...=== sounds like the metal door frame is in a commercial or apartment building and perhaps you can get the super or a neighbor to
Well, for starters, you don't use a hammer to drive screws. You won't even have much success in wood that way, never mind metal. And you don't use a special screwdriver to go into metal. You use the right screw, and you will need a drill or screw gun also. If there's metal around your door frame, it's probably a sheet of it, not solid. You drill a pilot hole and then use a sheet metal or self-tapping screw which can be driven using any screwdriver after the pilot hole is done, or you use a corded drill or a cordless screw gun to drive a self-drilling screw into the metal. You must use a power driver for that, and one with a bit of strength to it. A cordless screwdriver won't do it. You have to drill fast for some seconds so the head of the screw can drill its own hole. Once that happens, the threads will catch in a few very quick turns. Be aware of that because if you're not ready your hand and wrist can get wrenched around pretty fast as the screw drives home.
