What Are Sandwich Panel Screws?

Sandwich Panel Screws are specialized self-drilling fasteners designed for fixing insulated sandwich panels to steel or structural substrates.

These screws feature a high-performance drill point, strong threads, and sealing components that allow the screw to drill, tap, and fasten in a single operation without the need for pre-drilling.

This greatly improves installation efficiency while ensuring secure panel fixation.
