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.
a) A ribbed neck screw is a type of fastener designed with a special feature on its shank or neck. Instead of a smooth or threaded surface, the neck of the screw has ribbed, serrated, or knurled features. These ribs or serrations provide additional grip and resistance when the screw is driven into a material, preventing it from rotating or loosening.
