Pan head machine screws are machine screws with heads that are flat on top and rounded on the sides. They are typically used where a hex head might catch or would appear out of place. Slot screw head has a single horizontal indentation (the slot) in the fastener head and is driven by a flat-bladed screwdriver. Stainless steel is a family of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting, as well as providing heat-resistant properties.
