Spring Return Hydraulic Stud Tensioners

Spring Return Hydraulic Stud Tensioners

The MTT SPX SRT Spring Return Hydraulic Stud Tensioners are the quickest and most efficient stud tensioners available. Our hydraulic stud tensioners include a spring return load cell to expedite ram retraction. The SPX SRT’s are lighter in weight and offer a host of safety and fail-safe features such as the safety relief valve to eliminate over stroking the ram and having to change the seal.


The Spring Return design dramatically increases productivity and safety on the job site when compared to older technology manual return tensioners.
