The incorporated washer, on the other hand, serves multiple purposes. Primarily, it increases the bearing surface, thereby distributing the load from the screw more evenly across the material it's screwed into. This prevents damage to the surface, such as splitting or indentation, which can occur when a screw is tightened without a washer. Additionally, the washer can also help in reducing friction and preventing loosening due to vibration.

In terms of materials, hex head drilling screws are often made from high-strength steel, stainless steel, or a combination of both. High-strength steel screws are ideal for heavy-duty applications, providing exceptional resistance to shear and tensile forces. On the other hand, stainless steel screws offer excellent corrosion resistance, making them suitable for outdoor projects or environments prone to moisture. The choice of material ultimately depends on the specific requirements of the project at hand.
