The hydraulic nuts are used in all those applications where it is not possible to use a mechanical nut due to the need for continuous maintenance operations, heat, vibrations or other factors. • They replace the traditional mechanical nuts and ring nuts, guaranteeing superior and controlled tightening values, they are made according to the dimensions and the strength required by the user. • They are used in the naval, iron and steel and mechanical sectors. • The hydraulic nuts can have various threads, forces, pressures and dimensions based on specific project requirements. Very high pressure lever pumps, electric or air control units from 700 bar up to 3000 bar can compose and operate the hydraulic system. FPT – Fluid Power Technology is a manufacturer of hydraulic nuts, a product that replaces the existing hexagonal nuts to provide a punctual and uniform load at each bolted joint. They allow the tensioning of large diameter bolts with ease and with high and precise preloads. The tightening operation is carried out in narrow spaces and it is possible to eliminate the torsional stresses due to the damage to the thread. They can have upper or lower clamping collar, they are extremely compact, moreover it is possible to connect together any number of hydraulic nuts for simultaneous operation, guaranteeing uniform tensioning. They are used in all those applications where it is not possible to use a mechanical nut due to the need for continuous maintenance operations, for high temperatures or strong vibrations.
