Transcat stocks hydraulic tensioning equipment that delivers rapid, consistent performance, including tools designed for specialized applications. Hydraulic bolt tensioners are tightening tools for applying controlled bolt loading with high accuracy. During the tensioning process, the detachable tensioner is placed over the fastener to be tightened, hydraulic pressure is applied and the bolt is stretched. The load from the tensioning tool is proportional to the applied hydraulic pressure. Once the bolt is accurately loaded, the tensioner is removed. Tentec Limited leads our line of tensioning equipment featuring innovative designs.
