If the nail protrudes slightly above the surface and the head is intact, there will be no particular problem, only a nail pull is required, designed specifically for pulling out. However, if there is no hat, there is nothing to hook the nailer, it turns out to be useless.
The first, fairly simple way to pull out a nail without a head is to use side cutters. In order not to damage the surface, you can put a piece of tin can underneath. You can also place a wooden support between the pliers and the part. The main thing is to firmly grip the nail, which is quite difficult to do without a cap. Then, pressing on the handles of the pliers and tightly holding the nail, we begin to swing it, slowly, from side to side, in order to gradually pull out.
Nippers may not be enough if the nail is too deep in wood or other surface, there is simply nothing to grab onto. In this case, we offer the second option: you can go from the opposite and do it with a nail, another nail, a beard, try to punch it through, through the whole board. The main thing in this case is to clearly hit the center of the nail without a cap. This method will not help if the nail sticks out in a too thick board or other surface that cannot be pierced through..
The third way to remove a stuck nail without a cap is by heating. Remember from the physics course that when heated, bodies expand? And then, cooling down, they shrink, respectively. You can heat the nail and the surface around it either with a gas burner, or with some thin hot object, by applying. The metal will expand, shrink, the adhesion to the surface will become less strong and it will be possible to pull out a stubborn nail with the same pliers.
The fourth option: take a piece of pipe, the diameter of which exceeds the diameter of the nail. One end will have to be serrated, the other – inserted into the drill. Then simply drill out the nail, setting the serrated tube so that it is in the middle. The nail is quickly removed, but a hole remains, which, if necessary, can be closed with a plug or putty.
If you are not afraid to damage the surface into which a nail that has been left without a head is driven, you can try to get to it with a chisel, breaking off pieces of wood around it, in addition, you can also drill a hole nearby with a drill with an ordinary drill.
You can also make grooves on the sides of the nail, form cuts below the broken off top, in order to then pull out with nippers. Minus – the board or other surface will be damaged, a torn hole will remain in the place of the pulled out nail.
As you can see, pulling out a nail is much more difficult than driving it in without a hammer. However, ingenuity, the right tools, and, to be honest, brute force will help you cope with this task..
