I am assuming your talking about a galled thread in an oil field? A galled mechanical thread in an oil field or any other type of application is known as: a condition where the threads & or mating threads gall, seize, or form a burr due to misalignment, fatigue, or failure...etc. Typically different materials for the mating components are used to prevent this galling. A typical use for the word is: the threads are galled up meaning they dont fit properly or are very hard or unable to loosen.

Galled threads are threads that are messed up. This can be caused by several things. Misalignment while making up, making up to fast, improper application of thread compound, the wrong type of thread compound, or over-torqueing. Or also from just being made up too many times. Some threads can be field repaired, it just depends on the type of thread and how much load it has to bear. On some connections the threads and thread compound act as a seal, on others they have a metal-to-metal seal and the threads only bear they load. If you have more questions feel free to contact me.

Thread that has been galled is typically on the bolt. The thread will no longer be "sharp" as a new thread. The tip of the thread will appear to be worn down or laid over. It will make the match to the nuts much harder to make up and may be bad enough to cause the nut to slip on the bolt under load.

Seems like a reasonable explanation, or massive deaths of most of the flora and fauna due to a meteor impact or other such tragedy would be reasonable as well. However the Flood, is not as we know that oil and coal do not form naturally in under 6000 years. Then there is the problem with radiometric dating showing that the deposits date back millions of years. Before you start quoting old arguments about C-14 dating based on how the technology was 50 years ago, just realize that radiometric dating uses several different families of isotopes and compares ratios of parent to daughter isotopes (this accounts for differing amounts present in the substance).
