The CN Series Stretch-to-Load HYTORC Nut™ is the modern day replacement of Multi-Jack-Screw Nuts and Hydraulic Bolt Tensioners for a hands-free safe bolt load accuracy within 7%

The CN series clamp line covers a wide range of sizes and applications. The CN Series clamp was originally specified to replace fasteners that were operated with hydraulic bolt tensioners. The through bolt design of the CN Series HYTORC Nut™ makes them an appropriate choice for applications with high stud extensions. The outside diameter of a CN Series HYTORC Nut™ is approximately the cross corner dimension of a standard heavy hex nut.

CN Series clamps are typically specified for applications with minimal radial constraints. The relatively thick outer sleeve of a CN Series HYTORC Nut™ minimizes stresses and allows them to handle high loads at elevated temperatures.

The CN Series HYTORC Nut™ is composed of three components:

• Outer sleeve
• Inner sleeve
• Washer

As the outer sleeve turns (blue arrow), the inner sleeve moves upwards
(red arrow). The washer spline rotationally couples the inner sleeve with the washer preventing the inner sleeve from turning while providing a solid

BENEFITS
