The evolution of contemporary manufacturing has taken a big leap. Since the olden times we have used wood, stone, sap and strings until modern components. Our ancestors employed many techniques to make structures and objects. Alternative ways to lock two parts into a single structure were eventually invented.

Everyone made use of some trees and plants for their sap as a variety of glue. Dowels made of wood were useful for locking pieces of furniture together. The discovery of metallurgy prompted the creation of metallic tools and other carpentry materials. Blacksmiths who were good enough to figure metal into smaller items created the standard nail. Improvements in technology eventually improved the nail to hold components along. By making spiral grooves on the nail, screws were created. They can be made from totally different metals however brass machine screws carry benefits.

Making furniture and other structures in the past requires that pieces are secured together. Using sap or wooden dowels to secure parts together take time. Parts need to be shaped to fit perfectly, while the sap needs time to dry out after application. Iron nails made it easier to join pieces of wood together. However, corrosion eventually sets in and destroys everything.

When materials other than the usual wood were used, nails could never again be utilized because of configuration precision and design. Plastics and metal required screws in order to maintain their shape. The advances of our modernization to fabricate metals into the accurate shape, made manufacturing development materials such as screws much simpler.

Machined screws are usually made of iron and other metals. The discovery of alloys further improved reliability of the materials. The number one advantage of alloys was the ability to resist corrosion, both from moisture and exposure to oxygen. Large scale manufacturing and construction required a high tensile metal, able to resist great strain and resist weathering. High tensile steel became the go to option. Brass on the other hand, gained popularity as a more cost effective choice for smaller assemblies.

Steel is an alloy created by combining carbon and iron. This ends up into a metal that contains a higher endurance compared to regular iron. Adding chromium results in stainless steel. Industries favor the use of high carbon stainless steel, enhancing the sturdy metal into something stronger, recommended for building colossal structures.

Brass is the result of a mixture of copper with zinc. It boasts a soft golden color and was traditionally used for creating ornaments and decorations. Malleability means it can be machined into various items. If you can visit museums, you will be able to notice a wealth of adornments still in fine condition, proving the alloy can be quite durable

Brass would undoubtedly be the alloy of choice, due to the fact that it is cheaper to produce. Heat conductivity is top notch because it has a low melting point. Great acoustic properties also make it a good material for musical instruments.

One important property of brass has often been ignored. The germicidal ability of copper lends a powerful advantage. Machines and containers that are required to be sterile could benefit from the antimicrobial ability of the copper content.
