Bolts have "land" below the head and screws are threaded all the way up to the head.

What do you call this fastener?



Thanks

That's a Wood screw (not made of wood of course - although I'm sure someone has a picture?)

Just to clear this up. A screw is a sexual activity and a bolt is running away afterwards.

Folks, the etymology of both words makes the subject crystal-clear... a bolt comes from the ancient technology of the crossbow which was invented in China at around the same time they came up with paper, the wheel, fireworks and soy sauce. Thus the word 'bolt' is applied to anything that shoots through its target. It follows that to keep a bolt in place, you have to add something else - usually, although not always, a nut, which requires that the end of the bolt be threaded. Some bolts shoot through things that do not require threads, eg a door latch.
Screws on the other hand were invented by Archimedes and his mates. A screw is anything that has a thread and goes round and round.
QED.

Nut screws washers and bolts?
