2. Self-Drilling Capability One of the standout features of Tek screws is their self-drilling point, which simplifies the installation process and enhances efficiency. This feature is particularly beneficial in applications where precision and speed are crucial.

In addition to creating a watertight seal, metal roofing self-drilling screws are also highly durable and long-lasting. They are typically made from stainless steel or another corrosion-resistant material that is able to withstand the elements and resist rusting. This ensures that the screws will maintain their strength and integrity over time, providing a secure attachment for the metal roof.

Countersunk chipboard screws are specialized fasteners designed for joining chipboard and other materials. Unlike traditional screws, these screws feature a tapered head that allows them to sit flush with the surface of the material when installed. This design is particularly beneficial for aesthetic purposes and ensures that the screw does not protrude, which can be a safety hazard and may affect the finish of the project.
