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.

4. Minimal Drilling Requirements While standard anchors often require larger holes and more invasive installation processes, resin anchors can be installed with comparatively smaller holes, minimizing damage to the concrete and allowing for a more efficient installation process.

4. Corrosion Resistance Many hex head self-drilling screws are coated with various finishes to enhance their corrosion resistance. This is crucial for outdoor applications where exposure to the elements can lead to rust and degradation over time. Options such as galvanized or stainless steel coatings can provide extended lifespan and reliability in harsh environments.
