Easy Installation of DIN 7504 A2 Stainless Steel Screws

The DIN 7504 A2 Stainless Steel Screw demonstrates a high degree of ease of installation. It does not require pre-drilling of holes in the workpiece.

The screw’s bit automatically creates a hole of the right size when drilling into the workpiece, ensuring that the threaded portion of the stainless steel self-drilling screws can be smoothly accessed and locked. This feature greatly reduces installation steps and time and improves work efficiency.

Quick Installation

DIN 7504 A2 stainless steel screws are designed for efficient installation. The screws have a cutter head at the end of the screw, which can be directly applied to the metal plate during installation without the need for pre-drilling. This quick installation greatly shortens the project cycle and improves work efficiency.
