摘要 |
A slip on nut and reverse cut die is provided for dressing the threads of a wellhead or other item. A nut is provided that may be slipped onto a threaded section, past any damaged threads, without engaging the threads of the threaded section. Once positioned on a threaded section the nut may be tightened as desired. When removing the nut the reverse edges of the nut may repair or even cut new threads into the threaded section. |
