A1 Stainless Steel Pan Head Machine Screws

Pan Head Machine Screws have rounded edges to the head and finish on top of the surface. They are available with the following popular drive variants; Slotted, Pozi, Phillips and Torx. Invariably fully threaded, pan head machine screws are a multi-purpose screw with a raised head shape sitting proud of the surface, rather than being sunk into it. Also known as Cheese Head in some countries, but this is not necessarily an accurate description, as the head shape differs from the cheese head shape we know and love. Pan Head Machine Screws are used in many electronic applications and is a good all round fixing. Available in A2 stainless, A4 and in some cases Low Carbon Steel.
