Q: I need a flat head screw that is both non-Conductive Fastener and can survive shock and vibration. Any ideas?

A: Polymers and ceramics are the only options for non-conductive screws. As ceramics are brittle, they would non withstand shock and vibration. In terms of polymers, PEEK is the go-to option for a high strength. PEEK screws are the strongest polymer and will be your best bet to handle shock and vibration.
