Hexalobular socket pan head screw

a) The screw head features a hexalobular socket, often referred to by the generic name “6 lobe”

b) The flat underside of the pan head distributes clamping force over a larger area compared to countersunk or round head screws.

c) Although there may be minor differences in dimensional tolerances or thread requirements, both DIN 7985 (German standard) and ISO 14583 (international standard) specify pan head screws.
