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.

The M12 in the term refers to the metric screw thread size, which measures 12 millimeters in diameter. This size is commonly used for medium to heavy-duty applications where robust anchoring is crucial. Chemical anchors, unlike mechanical anchors, rely on a chemical adhesive to create a strong bond between the anchor and the substrate. They offer advantages like high load-bearing capacity, resistance to dynamic loads, and minimal impact on the surrounding material.
