Simple · Fast · Reliable
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 unique in the fact that the pretension 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 correct pretension force. This eliminates the need for complex, bulky, or heavy tools and makes securing large bolted joints more convenient and easy.
COMPATIBLE WITH DIN EN ISO 898-2
HEICO-TEC® Tension Nuts meet all the requirements of ISO 898-2 which enables you to easily replace any hex nut from the same strength class while also offering all the advantages of a hand-tightened nut.
