TN Series

Compact Style Replacement Nut

HYTORC 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 HYTORC TN Series Clamp Nut 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.

The HYTORC TN Series clamp line covers a wide range of sizes and applications. The TN Series HYTORC Nut™ was originally specified to overcome the tight radial restrictions found in steam turbine casings. The compact radial footprint has made the TN Series HYTORC’s most popular clamp. When a bolted connection has a challenging counter bore or flange radius, a HYTORC TN Series clamp will solve the problem. The HYTORC 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.
