Unscrewing a stuck screw with damaged thread

[barb1314]

My friend is trying to unscrew a corroded screw from a door and is having major problems.She has now damaged the thread whilst trying to undo it. Any solutions from anyone? Many thanks

The only way to do that is to get a kit where you can drill and tap a hole in the screw but off course it has to be an anti clockwise thread.

Or you could do it the old fashioned way with a hammer and screwdriver and hitting the screw in an anti clockwise direction to loosen it and when its loose you might be able to unscrew it.

If you damaged the slot where the driver goes, you have a prob. 2 ways. One is to get a fine pointed punch, and tap the outer edge of the screw antin clock. Or if you can get the driver in enough, to impact the end of the handle as you turn, a little ata time. Or drill it out. Or get the hinge off, and get a pair of bull nosed pliers with a strong wrist, to remove what is left. Trial and error.

There is an advertisment on TV about a drill which you can buy from Woolies, Wilkinsons. which if you have a drill which turns anti clockwise with a hammer action will undo most obstinate screws. I expect a friend must have one who will help if your friend buys it. The only other method is drill it out, and refill the hole with a mixture of wood adhesive and fine sawdust which when dry will hold a screw better than previously. A lot of work, but worth it.

Thanks to you all for your answers. I knew someone on here would help. I have told her and now she has Sunday's challenge! Thanks again.

I have used an ordinary drill slightly thinner than the screw. It must be sharp, a new one is best. Carefully drill down the length of the screw. This will remove most of the metal of the screw and it is usually easy to prise away the remains of the head and thread with a small screwdriver and pliers. If replacing the door, use a slightly thicker screw to ensure a good fix. Hope this helps
