Bolt Tensioner

Hydraulic Bolt Tensioner is used for tightening multiple bolts/nuts simultaneously and achieving the same clamping force. Hydraulic powered bolting tool heads are connected in sequence with high-pressure hydraulic hose assemblies to a single hydraulic-powered source. Depending on application numerous heads can be used or only a few, in critical gasket seals for pressure pipes all studs are fitted with tensioner heads.
