Super nuts, the huge preload force is decomposed into several small component forces along the axial direction, using the principle of thread gain, the jacking screws are tightened symmetrically one by one, and a huge axial preload force is applied to the connected parts.
The pre-tightening of large-size bolts can be realized without tools such as hydraulic bolt tensioners, torque multipliers, and hydraulic wrenches. Super nuts are not restricted by the use environment and are easy to maintain, and are increasingly favored by mechanical engineering design and maintenance units.
All items are produced in strict accordance with industry standards or customer-specific requirements.
