Wing Nut
 Liberals,is Jon Stewart a right wing nut now for saying ACORN are a bunch of criminals? Gee he sounded just like Glenn Beck and Sean Hannity tonight. See how they cover for him. Stewart told the truth at least this one time, they are criminals and so are each and every one who is involved with them in any way, shape or form. All need to be arrested, starting at the top, in DC. |

Fastener Nuts Bolts Screw
A nut is a type of hardware fastener Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, adhesives, safety pins, and other tricks are used to prevent fastener rotation. The most common shape is Hexagon, for similar reasons as the bolt head - 6 sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to stripping/rounding. Other specialized shapes exist for certain needs, such as wing nuts for finger adjustment and captive nuts for inaccessible areas.
A screw used as a threaded fastener consists of a cylindrical shaft, which in many cases tapers to a point at one end, and with a helical ridge or thread formed on it, and a head at the other end which can be rotated by some means. The thread is essentially an inclined plane wrapped around the shaft. The thread mates with a complementary helix in the material. The material may be manufactured with the mating helix using a tap, or the screw may create it when first driven in (a self-tapping screw). The head is specially shaped to allow a screwdriver it in or releasing it. The head is of larger diameter than the body of the screw and has no thread so that the screw can not be driven deeper than the length of the shaft, and to provide compression.
Screws can normally be removed and reinserted without reducing their effectiveness. They have greater holding power than nails and permit disassembly and reuse.
