if the head of a screw has sheard off how do i get that screw out of something metal without a drill?

Question

if drilling is the only way what kind of drill/bit would i need?

Answer 1

Try cutting a slot in the top of what is left of the screw and unscrew it with a flat bladed screwdriver, or if a bit of it is sticking out you could unscrew it by clamping mole grips onto it.

Answer 2

Ok here is how you MAY be able to do it without a drill. Get a centre punch (a manual type not an automatic type) put the tip of the centre punch on the outside edge of the broken screw and tap with a small hammer ANTICLOCKWISE to slowly undo the screw. The temptation is to hit down but you must hit the punch in the direction you want the screw to go and you must be paitent. People have a tendancy to hit to hard and just chissel bits off the screw, remember the screw must be tight or the head would not have broken. Once you have a decent "dent" in the part you are hitting you can hit a bit harder.

Otherwise you need a drill and something called an easy out (good hardware stores or motor factors will sell them). This is a device that has a reverse screw thread so as you tighten it up it undoes the screw, but to use that you need a drill.

I am assuming that you can not get to the broken screw at all, like you can not cut a slot into it or get a set of grips on to it.

Answer 3

If you can't get a hold of the screw with pliers you will need to drill.
If you want the screw out but don't want to damage the metal around it... use a drill bit that is smaller than the screw. Drill dead center of the screw ( be careful) when you have a good hole you can use a screw extractor (home depot, advanced auto napa etc)
The screw extractor will turn the screw out. If that's not an option..
After you have drilled try using a flat head screw driver to turn it out.
Good luck

Answer 4

What size is the screw (diameter)? I assume that you are talking about a machine screw and not a wood screw??

If you don't want to damage the surroundings, you will need a drill just below the screw size, keep it straight and drill away the screw, you can then pick out the remains of any threads left, and then run a tap through to clean it up.

Answer 5

If it extremely is skinny metallic you ought to use a sheet-metallic screw (self-tapping screw). If it extremely is thick, that's superb to apply a everyday threaded screw and drill and faucet the hollow to take that thread. yet for which you relatively prefer a faucet and faucet wrench. Or, you ought to use a sheet-metallic screw that's merely too enormous to freely flow interior the hollow, i.e. drill a greater robust hollow than you may use in actual sheet-metallic. Or drill a hollow top by way of and placed a nut the different area with a lock-washer that breaks the paint and makes stable electric powered touch. specific, merely drill yet another hollow. in case you attempt and drill out the old screw you will merely make a large number because it extremely is possibly greater sturdy than the metallic it extremely is screwed into.

Answer 6

Not much to go on here, and you have some good answers, but if the Metal piece being held is small, remove all the screws holding it in place, then remove the Metal object, the screw will now be exposed , hopefully long enough to grip it with Vice Grips,

Answer 7

If the end is sticking out, use a vice grip to turn it out manually. If not, your best bet is to use an extractor bit, or just redrill the hole through the screw. But then you'll need a tap to rethread the hole (if it's a thicker metal where the hole was threaded). Sounds like you're in a fix, so I hope you have some tools handy.

Answer 8

If its possible and you have them, you can use either a center punch, or a small chiesel. With either one you will have to tap on one of the sides in the oppisite direction the screw is put in. If its in metal you can use the chiesel to give yourself a little room to get a pair of needle nose vise grips in to grip the screw. Hope this helps you out. Good luck.

Answer 9

is it screwed onto wood? if so, chip away along the sides with a standard screwdriver, then use a bottle-nosed pliers to twist and yank it out of place. if it's screwed on any other surface such as concrete or metal, then i can't think of any other way but to use a drill (or an extremely powerful electromagnet). :)

Answer 10

Without a drill??? Hmmm You can use metal glue and glue something to the metal screw and then try to turn it. Why don't you want to drill it?
