What screws to use to fasten PVC?

To fasten PVC, it's best to use corrosion-resistant screws, such as stainless steel or galvanized screws. Specifically, self-tapping screws designed for plastic or dedicated PVC screws work well, as they create a secure hold without splitting the material. Make sure to pre-drill pilot holes to prevent cracking and ensure a tight fit. Additionally, use screws with a flat or pan head for a flush finish.
