ABOUT FATIGUE TECHNOLOGY INC.
Fatigue Technology Inc. (FTI) is a world-leading aerospace engineering and manufacturing company. FTI
pioneered Cold Expansion (Cx™) technology (which provides solutions to fatigue problems associated with holes
in metal structures) back in 1969 and has advanced this science to develop innovative bushing and fastener
products. These proprietary products and associated tooling may be covered by patents or agreements owned by, or
exclusively licensed to, Fatigue Technology Inc. Use of tooling procured from other than a licensed source may
constitute patent infringement.
The detailed tooling information in this manual was compiled and written by FTI. The tooling was designed
specifically for use with FTI’s Cold Expansion systems. FTI cannot be held responsible for damage or injury as a
result of operating this equipment if it is used for other than the process intended, with any other tooling not
provided by FTI, or not used in accordance with the instructions contained in this manual. To avoid personal
injury, please observe all safety precautions and instructions. FTI reserves the right to change specifications or
configurations of equipment detailed in this manual as part of our ongoing technical and product improvement
programs. If you have any questions about the use or serviceability of this equipment, please contact our Sales
Department.
