3. Versatility Tek screws are available in various sizes and coatings to suit different environments and materials. This versatility allows them to be used in a wide range of applications, from residential projects to industrial construction.

The white wafer head of these self-drilling screws is characterized by a broad, flat surface that provides a wide bearing area. This design helps distribute the load more evenly, reducing the risk of damage to the material being fastened. The head is typically finished in a white coating that not only enhances aesthetic appeal but also offers a degree of corrosion resistance, which is particularly beneficial in outdoor applications or areas exposed to moisture.

Screws are another essential type of structural fastener, distinguished by their helical threads. They provide excellent holding power when driven into materials like wood, metal, or plastic. Common screw types include wood screws, machine screws, and self-tapping screws. Wood screws are designed specifically for use in wooden materials, while machine screws are used in conjunction with nuts or tapped holes in metal. Self-tapping screws, on the other hand, create their own thread as they are driven into the material, eliminating the need for pre-drilling.

The versatility of 13mm self-drilling screws makes them suitable for a wide array of applications. In the construction industry, they are often used for securing metal sheets, roofing panels, and siding. Their ability to drill into hard materials without the need for pre-drilling makes them invaluable for contractors working with metal framing or installing cladding systems.
