self drilling screw hex washer head

Rubber washers are circular disks made from rubber or synthetic elastomers, often used to create a seal or cushion between two surfaces. When paired with hex head screws, these washers serve to enhance the effectiveness of the fastener by providing a barrier against moisture, dust, and other elements that can lead to degradation over time. This is particularly important in outdoor applications or environments where exposure to the elements is a concern.

Washer head machine screws are characterized by their broad, flat heads that resemble a washer. This design provides a larger bearing surface than standard screws, which helps distribute the load more evenly across the material being fastened. The head’s geometry often includes a recessed area for a driver, facilitating easy installation and removal. Additionally, these screws are typically made from high-strength materials such as stainless steel, carbon steel, or alloy steel, ensuring durability and resistance to corrosion and wear.
