As with the other HEICO-TEC® mechanical tensioning products, the new HEICO-TEC® Tension Bolts are based on the same functional principle: taking a large bolted joint’s hard-to-manage main thread preload requirement and dividing it into many smaller, easier-to-manage force requirements.

​

The HEICO-TEC® Tension Bolt's key advantages are accuracy, simplicity, reliability and safety.  For example, a worker can tighten/loosen HEICO-TEC® Tension Bolts with simple hand tools instead of other costly and complicated tensioning methods.

​

HEICO-TEC® Tension Bolts are specifically designed for applications with tight spaces. Compared to a conventional stud + hex nut bolted joint design, the solid, one-piece HEICO-TEC® Tension Bolt requires much less outside diameter and head height space allowances.  This one-piece design further simplifies operations and logistics in doing away with the traditional two-piece stud + nut arrangement.

​

As with the HEICO-TEC® Tension Nut, the HEICO-TEC® Tension Bolt creates torsion-free preloads in the main bolt avoiding the potential for thread damage.  Wherever customers face tight installation spaces or require a single, easy-to-install tensioning device, HEICO-TEC® Tension Bolts provide the best solution.

​

We can offer our HEICO-TEC® Tension Bolts in strength class 8.8 as a direct replacement for conventional bolts of the same strength class in the dimension range of M20-M100.  HEICO can also satisfy specific customer requests with imperial/inch sizes, unique designs, higher strength classes or other special requirements.
