CTST Series - Topside Bolt Tensioners

The use of Tentec's Bolt Load Software package along side the CTST range of bolt tensioning tools completely removes the complexity of calculating what pressure to operate the tensioning tools. A complete bolt tensioning project can be defined and rapid joint specific technical datasheets can be produced with all the information that the operator of the equipment needs to successfully tighten the bolted joint.
