HYTORC NUT

The HYTORC NUT is a 3-part tensioning system for extremely difficult applications. The special construction lets the bolt move with the inner sleeve without side loads, torsion or reaction because the nut does not turn on the flange surface. The bolts are 100% mechanically tensioned. The solution combines the best features of bolt tensioning with hydraulic torque wrench usage. The method is in use on many critical applications from nuclear reactors to turbines and above all where ever time usage in bolting operations needs to be minimized.

  • Eliminates the need for bolt elongation measurement
  • Precision straight-pull tensioning with calibrated bolt load accuracy of +/- 5%
  • Suitable for even tight spaces and high temperatures up to 537°C
  • No reaction arm or reaction point needed
  • Fast and simple to use
  • Reusable

GRIP-TIGHT NUT

Protect your commercial fleet from wheel installation related incidents with the new HYTORC Grip-Tight Nut. The Grip-Tight Nut is an instant upgrade for all heavy-duty truck and trailer hub piloted wheels. The patent pending Grip-Tight Nut eliminates the influence of side loads and provides a pinch point free reaction component for applied torque. The HYTORC Grip-Tight Nut can be torqued using the proprietary Grip-Tight Driver with next-generation portable electric torque tools such as HYTORC Lion or HYTORC Lithium II and pneumatic jGun torque guns.

  • Washer profile acts as a coaxial reaction point which eliminates pinch points and removes undesirable side loads
  • Increases efficiency, quality and safety of wheel nut installations
  • Made from through-hardened and tempered chrome-moly steel
  • M22X1.5 threads

GALL-FREE NUT

In industry, seizures are an expensive by-product caused by high friction, temperatures and side loads. HYTORC Gall Free Nut is the new anti-galling technology in a standard hex nut. The new Gall Free Nut thread design eliminates metal transfer that may occur in fasteners without lubrication and increased friction over extended time periods. This technology counters the galling effect of plastic deformation and micro-scale material transfer at the thread surfaces that occur during assembly.

  • Guaranteed operation even at high torque forces and temperatures
  • Standard thread size nuts are available in a variety of materials and coatings
  • No need for thread lubricants
