Fastener Nuts Bolts Screw
Executive Summary about : Bolts Screw by pntglobal
A nut is a type of hardware fastener Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. Other specialized shapes exist for certain needs, such as wing nuts for finger adjustment and captive nuts for inaccessible areas.
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). Screws can normally be removed and reinserted without reducing their effectiveness.

How to Remove Rust From Bolts and Screws!
Executive Summary about : Bolts Screw by Markus Skupeika
Especially if those bolts and screws are left open in moisture for long, they will grow rust very soon. For example screws and bolts in car parts, boats or even lawn mowers often get rusted as they are almost always open to moisture. The problem becomes more intense once rust gets into the threads or when rust eats up the metal head of the screw making it difficult to grip with a screwdriver.
People try different things in similar situation to remove rust and open those screws and other metal bodies. Here are some common ways that people use to effectively remove rust:
The most common solution is using penetrating oil bought from local hardware store. If necessary you may even need to use a narrow chisel and a hammer to move the rusted screw inside. Some people prefer using hydrogen peroxide on rusted screws and bolts. After a while you would need to use a hard brush and clean the rust from the screw. You may also need to use some oil after cleaning the rust on it so that the screw comes out easily. Good quality rust cleaners do not require scrubbing and brushing - all you need to do is to dip the rusted metal into the cleaner. If you want to do that in harder way, try using some fine grade sand paper and sand out all rust from the screws and bolts. There are lots of other ways people employ to remove rust from metal items.
Nuts and Bolts: The Lowdown
Executive Summary about : Bolts and Nuts by James Monahan
However the functionality bolts provide as one of the most used fasteners is unparalleled.
Fasteners cover everything from nails to rivets and bolts. In the USA, about 600 companies make fasteners. They employ about 60,000 workers, and make about 250 billion fasteners each year, bolts included.
Threaded fasteners, which include common nuts and bolts, serve one primary function. The Romans invented the first screws to fasten wooden parts together. Apparently, nobody noticed Leonardo Da Vinci’s designs from the late 1400’s for screw-cutting machines, because first machine to cut screws was built in 1568 by the French mathematician, Jaques Besson.
Bolts are basically just screws that had straight sides and had blund ends. The nut, the bolt’s partner in crime was hand-made and very crude. Between 1800 and 1810, his invention turned the relatively benign art of nuts and bolts into a serious engineering science.
Uniform standards for the shape of fastener threads - the little hills and valleys and sizes - did not exist. In 1841, Joseph Whitworth delivered his paper A Uniform System of Screw-Threads to the Institution of Civil Engineers. Without nuts and bolts, many industries would have a hard time keeping things together. For the mechanic, the right supply of nuts and bolts is critical.
