Zusammenfassung:	The utility model relates to a high-prestress equal-strength full-thread anchor rod nut which comprises an inner nut sleeve and an outer nut sleeve. The inner nut sleeve is sleeved with the outer nut sleeve, the inner surface of the inner nut sleeve is provided with an inner nut sleeve inner thread matched with an equal-strength full-thread anchor rod body, the outer surface of the inner nut sleeve is provided with an inner nut sleeve outer thread, the inner surface of the outer nut sleeve is provided with an outer nut sleeve inner thread, and the outer nut sleeve inner thread is matched with the inner nut sleeve outer thread. The pitch of the inner nut sleeve outer thread is smaller than that of the equal-strength full-thread anchor rod body. According to the high-prestress equal-strength full-thread anchor rod nut, the rigidity of a supporting system is improved by improving the pretightening force of an equal-strength full-thread anchor rod.
