• It also happens that the faces on the bolt erased completely, and it is impossible to use the gas key due to its size. In such a case, the faces can be formalized. To do this, take a file and get the head to a smaller diameter. Then it will be possible to put on the appropriate sizes.
• Another way to extract hardware is to welcome the nut to its head and use it the faces to unscrew the fastener.
• If the bolt is very large, you can apply a layer of metal using welding to its head, and then weave it with a file, forming a hexagon.
