The 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 SRTs are lighter in weight and offer a host of safety and fail-safe features such as a safety relief valve to eliminate over-stroking the ram and having to change the seal. We offer both the sale and rental of the full tensioner line.
