HEICO-TEC® Tension Nut


For a secure joint with a HEICO-TEC® tension nut, no electric, hydraulic or pneumatic tools are needed. All you need is a torque wrench.
The HEICO-TEC® tension nut is a unique in the fact that the pre-tension force of the large main thread is distributed to many smaller pressure bolts. Because the pressure bolts are smaller, a conventional torque wrench can be used to achieve the proper pretension force. This eliminates the need for complex, bulky or heavy tools and makes securing large bolted joints more convenient and easy.
