Additionally, the corrosion-resistant properties of the white finish contribute to the longevity of the installation. Projects exposed to harsh environmental conditions benefit from this enhanced durability, ensuring that the fasteners will maintain their integrity over time.

The term 16mm refers to the length of the screw, which is about 0.63 inches. This size is particularly useful in various applications, offering enough length to secure materials without penetrating too deeply, thus maintaining structural integrity. While they come in various diameters and thread configurations, 16mm self-drilling screws can generally accommodate a range of thicknesses in materials, making them a popular choice in construction and industrial applications.

1. Self-Locking Mechanism One of the standout features of metal expansion nuts is their ability to lock into place without additional locking devices. This self-locking characteristic significantly enhances the safety and durability of applications.
