------------------------ With regards to fasteners (since there are other types of nuts, bolts and screws): A "nut" is the part of a fastener with the threaded hole. A "screw" is the part of the fastener with a threaded shaft. Unless it is an integral part of some larger assembly, it always has a head larger than the shaft. The shaft may be cylindrical, such as a screw that mates with a nut, or the shaft may be conical, such as a wood screw or self-tapping metal screw that does not take a nut. Obviously, a conical screw must be turned to tighten it since there is no "nut". A "bolt" is specifically a screw that is cylindrical: it always takes a nut. In the common vernacular, "bolt" is most often used to describe a large screw, (e.g. we usually refer to a "10/32 screw" but usually a "1/4-inch bolt"). Some bolts, like "stove bolts", have heads specifically designed to grip the material being fastened. They have a smoothly rounded top that is not designed to be gripped by a tool, so in that special case the nut is the part of the fastener that must be tightened. Egad! Even nuts, bolts and screws can get complicated!
