Key benefits
While hydraulic tensioners and hydraulic nuts rely on hydraulic pressure to generate preload, MT mechanical nuts achieve the required clamping force through a purely mechanical system, offering a simple, reliable, and cost effective solution for permanent bolted joints.
Accurate and repeatable results: Each unit is supplied with a dedicated torque-to-axial force chart to ensure precise preload control and repeatable tightening operations.
Improved safety and reliability: Delivers uniform load distribution, minimizes tightening errors, and helps maintain long-term joint integrity.
Easy maintenance operations: Can be installed, retightened, or removed quickly using conventional hand tools, reducing maintenance time and costs.
Wide range of applications: Suitable for heavy industrial equipment, steel plants, mining machinery, energy production systems, presses, and other applications requiring high bolt loads.
Custom-engineered solutions: Available in standard configurations or fully customized designs to meet specific dimensional, load, and application requirements.
Safe tensioning
Ensure there is sufficient stud protrusion. A minimum of 1 x stud diameter is essential.
Operations
Never stand in-line with the bolt axis during the tensioning or de-tensioning procedure.
Tensioning procedure
An accurate tightening sequence is required to ensure uniform load distribution.
