8 x 1 2 self drilling screw

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.

Wafer head reamer self-drilling screws are specialized fasteners designed to penetrate materials without the need for pre-drilled holes. The wafer head refers to its flat, wide design, which provides a large bearing surface. This shape helps distribute the load over a broader area, reducing the risk of material deformation and enhancing overall stability. The reamer design, on the other hand, refers to the screw's cutting capability, allowing it to create its own hole while drilling into various substrates.
