There are many types of carbon based materials, the actual name for this type of carbon is 'CFM Peek'.
You may have heard of 'Carbon Peek', which has been used in many F1 and fighter Aircraft applications in the past, but 'CFM Peek' is a material developed around a new manufacturing process.
In this process the manufacturer is able to control the orientation of separate carbon fibres within the component, creating a part many times stronger than standard 'Carbon Peek'. In fact these bolts have a proven higher yeld strength than steel! Although they are lighter than aluminium...
Use: To replace all standard Din M5 (5mm) & M6 (6mm) screws where the use of aluminium screws is permitted. Although these bolts have proven to be strong enough for most applications, these are still a very new product, and you should limit their use to items such as: bottle cage bolts, front mech. bolts, cable grip bolts etc...
