Wood nails is one of the oldest fasteners known to man and has been around for thousand of years.
Some of the first nails was heat forged then when our machine erra came about they were cut out from sheets of metal, now mostly they are manufacture from rolls of wire.
Wood nails are fasteners made mainly of various metals that are driven into wood or other materials with a hammer or nail gun.
With modern times, improved glues and the cordless screwdriver that are readily availible is now making the ease of using screws more common for the choice of the woodworker.
However though wood nails will always be around because there are projects where a nail is the most practical fastener to use.
Some of the common types of nails includes finishing nails, masonry nails, roofing nails, brad nails, double-headed nails, cap nails.
These are just a few of the many types of nails.The nail has a vast assortment of types and sizes and comes in different coatings also, for example a coated nail makes it easier to drive a nail into a dense piece of material. A galvanize

Nails are generally sold by weight in boxes or bulk. The US uses the term penny size and the length of a nail is designated by this term.
The term 'penny' is believed to have originated based on the old
custom in England. Nails that were sold by the hundred for six pence were then called six penny thus making the larger nails more costly and then in turn making the penny size of the nail greater.
A number and the abbrevviation d is how the penny size is written, (example 12d). D whichis a abbreviation for a Roman coin called a denarius that is similar to a penny.
The number is what indicates the size, for example a small number will be a shorter nail than one with ahigher number which will be a longer nail size.
This is how you can convert sizes up to 10 d, subtract 1/2" from the length of the nail thenmultiply it by 4. A example of this is a 3" long nail,
3"- 1/2" is 2 1/2" or 2.5 which is multiply
by 4 = 10 d.
You can also reverse this equation 10d divided by 4 = 2 1/2" then add the 1/2"making it 3 ".
