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. Pozidriv head design ensures screwdriver head does not cam-out. Zinc plated fasteners are the most common used plating. This ensures good rust-resisting qualities, appearance and low cost.
