HEICO-TEC

Heico Tec
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 nut is unique in the fact that the pre-tension force of the large main thread is distributed to many smaller pressure bolts. As the pressure bolts are smaller a conventional torque wrench can be used to achieve the correct pretension force thus eliminating the need for complex, bulky or heavy tools and making securing large bolted joints more convenient and easy. HEICO-TEC also meets the requirements of ISO 898-2 which means you can easily replace any hex nut from the same strength class.
