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 design of a bolt structure also involves careful consideration of its mechanical properties, such as tensile strength, shear strength, and fatigue resistance. Tensile strength refers to the maximum load a bolt can withstand while being pulled in tension, whereas shear strength is associated with the load bearing capacity when the bolt experiences forces perpendicular to its axis. Fatigue resistance is particularly important in structures subjected to repeated loading cycles, as it ensures that the bolt can withstand the wear and tear of regular operation without failure.
