Ahhh--that's a fine line. I think technically it would be a screw, even
though, as we Americans have been taught to think, it doesn't have a slot or
Phillips receiver, isn't pointed, and isn't conical.
I found this on the net: "Old SAE and USS standards made a distinction
between a bolt and a cap screw based on whether a portion of the shaft was
un-threaded or not. Cap screws had shafts that were threaded up to the head and
bolts had partially threaded shafts. Today a bolt that has a completely
threaded shaft might be referred to as a tap bolt."
"ASME B18.2.1 defines a bolt as 'an externally threaded fastener designed for
insertion through the holes in assembled parts, and is normally intended to be
tightened or released by torquing a nut'."
So the fastener that holds the pan to the engine would technically be called a
screw, although I, too, refer to it as a bolt, since it does not have a slot, a
point, nor is it conical, as a screw (shut up Ed) is to my way of thinking.
But then, again, it has no nut, so it fits the above description of a "screw".
