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.
No Galling: 100% elimination of bolt galling.
Improved Safety: No pinch points to worry about.
Pure Tensile Loads: Made to withstand high tension and shear load.
TN SERIES – TURBINE STYLE LIMITED RADIUS NUT
Our best-selling nut is engineered to solve the toughest challenges in steam turbine engines, especially when space is tight, and temperatures run high. Perfect for applications with tricky counter bores or flanged radii on bolted connections, making your job easier and more efficient.
GT SERIES – GAS TURBINE STYLE NUT
Designed specifically for gas turbines, this nut is built to withstand extreme heat, stress, and high loads. It's ideal for oversized applications, where you need extra power to break out and secure tight connections. If your job requires more torque and load, this nut is your go-to.
CT SERIES - CHEMICAL STYLE NUT
With a thicker outer sleeve to reduce stress, this nut is perfect for handling high loads at elevated temperatures. The through-bolt design is made for applications where stud protrusions are long, helping you maintain secure connections even in tough environments.
SN SERIES - LOW CLEARANCE STYLE NUT
The low-profile SN Series is designed for when space is at a premium. It's the perfect solution for tight overhead areas where traditional nuts don't fit. It's through-bolt design is a practical option for situations with high stud extensions, providing a reliable alternative when standard nuts just won't work.
