Schmolke's carbon screws are manufactured in a highly specialized pressure extrusion procedure. The material used is Schmolke's own high quality Intermediate module fibers with PEEK-matrix. This is the only means to make sure the fibers are arranged in a spiraling pattern following the thread and centered towards the inside of the screw. The actual thread can not be stripped. In terms of dynamic strength carbon fiber is much superior to all other materials used for screws. They are stronger and 40% lighter than aluminum bolts.
We do not recommend using these bolts in any load bearing application. Pinch bolts and water bottle cage bolts are perfect for replacing. For a full list please refer to Schmolke's list of recommended uses.
