TN - Compact Style Replacement Nut

The TN Series Stretch-to-Load ClampNut combines measurement-free bolt load precision, hands-free safety for the most radially confined areas.

TN Series Clamp Overview

TN Clamps were originally designed to overcome the tight radial restrictions found in steam turbine casings. TN Series Clamps combine durability and efficiency. One of the major advantages is the TN’s ability to fit in tight spaces. The TN Series ClampNut is used in conjunction with a coaxial action/reaction pneumatic or hydraulic torque tool.

Do you have a difficult counter bore or flange radius, no problem! We fit where others can’t.

There is no other bolting method available that is Faster, Safer or more Accurate then the TN Series ClampNut.

The TN Series clamp line covers a wide range of sizes and applications. The TN Series clamp was originally specified to overcome the tight radial restrictions found in steam turbine casings. The compact radial footprint has made the TN Series JETYD’s most popular clamp. When a bolted connection has a challenging counter bore or flange radius, a TN Series clamp will solve the problem. The TN Series compact size limits the maximum stud protrusion to approximately one diameter. TN Series clamps are typically specified when overhead obstructions are not present.

The TN Series clamp 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 reaction point for turning the outer sleeve.
