PEEK Screws for High Temperature Sterilization

Q: I have a high temperature sterilization process and am using PVDF screws. They seem to be weakening under the temperatures that approach 300F. Any suggestions?
A: PEEK fasteners may be a good fit for your application. PEEK screws stay strong and retain their mechanical properties to about 500F. They are also resistant to water and steam at high temperatures and pressures, as well as radiation sterilization.
