Hydraulic Nuts

HTI's line of hydraulic nuts are compact, easy to use, and provide a high level of accuracy. The hydraulic nut replaces the nut normally used, and stays with the stud. It is the most compact system and does not require additional stud length. The operator simply screws the hydraulic nut down tight and connects the hydraulic hoses. After reaching pressure, the operator either screws down a collar or inserts shims designed for the specific hydraulic nut application. Hydraulic nuts offer a number of advantages over traditional nuts.
