High Capacity Hydraulic Nuts

High Capacity Hydraulic Nuts

Hydraulic tensioning with hydraulic tensioners and nuts is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical fasteners. At HTI, we’ve been building hydraulic tensioners and nuts since 1986. 

HTI provides high-capacity hydraulic nuts for applications where a standard nut might not be able to provide the full force necessary to achieve the proper bolt loading. Some stud materials may require this.   

A high-capacity hydraulic nut can be especially helpful for subsea use, where performing an additional operation can be cumbersome, or when using multiple nuts on the bolting of a large assembly, where multiple cycles would be time-consuming. 

HTI standard hydraulic nuts can produce a maximum force of 996,730 lbf / 4,434 kN; above that force would require a high-capacity hydraulic nut. 

High-capacity hydraulic nuts will have a wider diameter than standard nuts as the increased capacity is achieved by increasing the (internal) surface area onto which the hydraulic pressure is applied. 

Custom Engineered Solutions Since 1986

HTI has been designing engineered solutions to your toughest bolt tensioning problems for over 35 years! Choose from one of HTI’s hydraulic nut catalog models or we can design a custom hydraulic nut for any application when a standard model won’t work. HTI hydraulic nuts can be designed for imperial or metric-sized studs. Contact us to start the process of getting the right tensioning solution for your application.
