If you have ever come across a nut and bolt that are completely stuck you know how frustrating it can be. When fasteners get corroded they can be very difficult to remove but it can be done. It just takes a little know how. Sometimes when the threads become stripped it can be very hard to remove as well but there are techniques that will help you get it out.
One of the things you can do is use penetrating oil and allow it to site for up to 30 minutes. WD-40 is a type of penetrating oil that is often used successfully. After you have let it sit, give it a light tap with a hammer and use a wrench, vise grips, or a socket to remove it. You may need to add a little more penetrating oil a second time. Remember that heat should not be used as penetrating oil is flammable. You will still need to work on it to get it out. Sometimes it will start to show signs of progress but then will get stuck again. If this happens turn it back in and then try to remove it once more. You may have to do this several times but with the combination of the penetrating oil and the turning back and forth you should be able to work it loose.
When the threads are stripped it can be difficult to remove a fastener as well. You can use a tap or a die to clean up the threads and then reinstall the fastener. Wood or fiberglass that has stripped hole can be patched with a wood filler or a gel coat or toothpicks or small pieces of wood can be glued into the hole. Then you just need to re-drill and install the fastener again. If the fastener that you are fixing is outside you should use silicone to prevent it from filling with water. Finally, you can also use a heli-coil kit, which gives you the ability to drill the out further and use a heli-coil insert. This will allow you to use the same sized fastener again.
