EN 14399-2, ISO 16047

Torontech’s TT-TTM Series of Torsion Testing Machine is designed to verify the suitability of high strength bolt/nut/washer assemblies for pre-loaded bolted connection in metallic structures.

The purpose of this test is to check the behavior of the fastener assembly so as to ensure that the required pre-load can be reliably obtained by the tightening methods specified in ENV 1090 with sufficient margins against over tightening and against failure.

The torque is generated by servo motor and gear box, the torsional angle is directly measured from servo motor, the bolt force and torque are also directly from load cells.
