What Are Nails Made Of Metal

Nails are a common fastener used in structure and woodworking applications. Consisting of a long and narrow piece of solid metal with a pointed tip and flattened head, they are used to secure two or more than objects together. Even if you don't use nails on a regular basis, y'all're probably familiar with this otherwise common fastener. However, you lot might be surprised to learn the following facts virtually nails.

#1) They Are Measured in 'Pennies'

The length of nails produced and sold in the United States is measured in "pennies." A 2d nail, for example, has a length of two pennies, whereas a 60d boom has a length of 60 pennies. With that said, y'all should interpret this measurement literally. A 2nd blast is ane inch longer, meaning it's longer than 2 actual pennies (the currency). Penny sizes for nails originated in England where merchants would price their nails according to their length.

#two) They Originated in Ancient Egypt

To say nails are an former fastener would be an understatement. Information technology's unknown exactly when nails were start invented, simply archeological evidence shows nails were used in Ancient Egypt around 3,400 B.C. Since and then, piffling has changed regarding their design.

#3) They Were Originally Handmade

Nails today are manufactured using a commercial boom-making machine. The automobile takes coils of wire and manipulates them into the shape of a nail. Depending on the type of machine used, it may produce as many equally 500 or 700 nails per minute. In the by, however, nails were handmade by workers known as slitters and nailers. The slitters would slice upward raw iron into an appropriate shape, later which they would pass the metal to a nailer.

#4) They Are Made of a Diversity of Metals

For centuries, wrought iron was the master metallic in which nails were made. While you can still observe wrought fe nails today, you can now find these fasteners made of other metals like aluminum, steel, copper, brass and silvery. Some nails, in fact, are even fabricated of wood.

#v) They Are Often Galvanized

To protect against corrosion, nails are often galvanized during production. There are three types of galvaniztion processes used during the product of nails: electrogalvanization, hot-dip galvanization and mechanical galvanization, all of which are designed to create a protective layer over the surface of nails.

#6) Some Take Two Heads

Non all nails have a single head. Some actually take two heads. Known as duplex nails, they let for easier extraction with the presence of a second head that'due south plant slightly lower than the original head.
