Metric DIN 921 slotted pan head screws with large head have pan style head (cheese head) with a significantly larger diameter than a standard pan /cheese head. The large head screw would typically be used in applications where the extra weight bearing surface under the head is required to allow for more a even distribution of clamping forces. The wider diameter also eliminates the need for a washer and is very helpful when the size of the hole through which the screw is inserted is considerably larger than the diameter of the screw.
