Best creep resistance polymer fastener

Q: How does creep occur and what polymer is best to prevent this?

A: Creep is the permanent deformation of the material caused by constant load or stress, usually accompanied by constant high temperature. This can result in permanent changes of the fastener shape as well weakening and fracturing of the material. Depending on your conditions, it may not be possible to completely prevent this but it certainly could be minimized with creep resistant polymer fasteners like PEEK. PEEK screws are extremely creep resistant and could be further strengthened with glass or carbon fiber reinforcement if needed.
