Roofing Nail
Galvanised nails for fixing corrugated iron. About 65mm long with an integral washer they are now superseded by roofing screws.
Furphy

The photo above shows a close up of one of the old nails used for fixing corrugated iron. They were about 65mm long and had a sometimes a serrated gripping shank, but most often they were plain. They came with the washer attached but it was common for the washer to separate from the nail head.

Some of these nails like the one in the photo had a slotted head. This is a definitely a "Furphy". Nobody, repeat, nobody has ever successfully used a screwdriver to pull out one of these nails.

The only way to pull them out is to place the claw end of a pinch bar just up to the edge of the washer and belt the bar with a hammer, driving the claw under the washer around the nail. This should always be done from the side so that when pulling out the nail with the pinch bar rests in the hollow of the corrugation to give a solid pull.
