The HYTORC Nut is a dual-spline mechanical tensioning device that applies pure tension to a bolt, to prevent thread damage and ensure load accuracy. The patented three-piece design provides industry-leading joint integrity for critical applications, eliminating windup and ensuring even bolt load to eliminate joint failure and unintentional loosening. The HYTORC Nut is available in a variety of materials and configurations to suit a wide range of industries, environments and applications.

Bolt Tensioner - Calibrated Load Accuracy

No other bolting system provides the same level of repeatable accuracy, ensuring even bolt load to eliminate joint failure and unintentional nut loosening.

Tool Longevity

Other bolting systems put the reaction arm and square drive on opposite sides of the tool causing high stress in the body of the tool, which can lead to failure over time. The HYTORC Nut puts the action and reaction on the square drive axis to eliminate the majority of internal stress, and increase the lifetime of your tools.

Gall-free Removal

The HYTORC Nut is the only fastener that can guarantee the elimination of galled or damaged threads on installation and removal. These fasteners have been installed on various high temperature applications for ten years and longer, and were removed without damage to the bolts, providing tremendous savings by eliminating the need for bolt replacement.
