13mm wafer head screws

The 'head' of the bolt refers to its top part that sits above the threaded shaft. It's the part that provides the gripping surface for the tool used in installation or removal. The hexagonal shape offers several advantages over other head designs. Firstly, it allows for better torque application, enabling precise tightening without slipping. Secondly, the six-sided profile can accommodate larger wrenches or sockets, which can generate more torque, ideal for heavy-duty applications.

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.
