5. Corrosion Resistance Many 2% self-drilling screws are treated with coatings, such as zinc plating or epoxy, to enhance their resistance to rust and corrosion. This feature makes them suitable for outdoor applications and environments exposed to moisture.

Self-drilling metal screws are essential fasteners widely used in construction, manufacturing, and automotive industries. Their unique design allows them to create their own hole in the material they're being driven into, eliminating the need for pre-drilling. This feature not only saves time but also enhances efficiency, making them a preferred choice for various applications.

The Function of Shear Studs

Tek screws are characterized by their unique, cutting-edge tip that allows them to drill into hard substrates without the need for a pre-drilled hole. This feature significantly simplifies the installation process, saving time and reducing the need for additional tools. Commonly made from high-strength steel and often treated to resist corrosion, Tek screws are built to withstand harsh conditions, making them suitable for use both indoors and outdoors.

2. Pre-drill the Hole For toggle bolts and expansion screws, it’s important to pre-drill the hole according to the manufacturer’s specifications to facilitate proper expansion.
