SteelFiber FC Iron S hafts are a high-performance iron shaft designed to provide players with a combination of the benefits of both steel and graphite materials. The FC in the name stands for “Flight Control,” which refers to the unique design of the shaft that helps players achieve a more consistent ball flight and distance control.

All SteelFiber FC Iron S shafts are made with a composite design that combines a high-modulus graphite core with steel fibers that are layered in a hoop pattern around the core. This design helps to provide the benefits of both materials, including the vibration dampening and lightweight properties of graphite, and the consistency and stability of steel.
In addition to the Flight Control design, SteelFiber FC Iron S shafts also feature a progressive tip stiffness, which means that the stiffness of the tip section varies depending on the specific model. This helps to optimize the launch and spin for each individual player based on their swing speed and other factors.
Another key feature of the SteelFiber FC Iron S shafts is the constant taper design, which provides a consistent and smooth transition from the thicker butt section to the thinner tip section. This design helps to optimize the energy transfer and feel of the shaft.
Overall, the SteelFiber FC Iron S shafts are a high-performance option for players looking to improve their iron game with a combination of the benefits of both steel and graphite materials. The Flight Control design, progressive tip stiffness, and constant taper design all work together to provide a consistent and optimized performance for a wide range of swing speeds and player types.
