Fixed Standard Return Tensioners
Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At HTI, we’ve been building hydraulic tensioners and nuts since 1986.
HTI’s fixed model stud tensioners are designed to fit specific stud sizes. Fixed models are easy to use, accurate, compact, and economical. HTI fixed model tensioners are simple to operate and maintain, designed and built using Total Quality Assurance, and provide extremely dependable operation. With HTI hydraulic tensioners, the stud can be exactly tensioned to the required bolt load; stud tensioning is the optimum method used to achieve proper bolt loading.
Sizes range from ¾” to 4” imperial and 18mm to 100mm metric. See our full specification sheet for detailed model information.

Custom Engineered Tensioners Since 1986
HTI has been designing engineered solutions to your toughest bolt tensioning problems since 1986! You can choose from one of our standard catalog sizes above, or we can design a custom fixed tensioner for any application when a standard model won’t work. HTI tensioners can be designed for imperial or metric-sized studs, high loads, high temperatures, large stud sizes or corrosive environments. Our multi-unit tensioning systems can make easy work of large bolted systems, and our automated tensioning systems can reduce labor and increase throughput in high-volume manufacturing applications.
