All about screws and bolts

234226936Screws and bolt belong to a group of threaded fasteners. The threads can run right handed or left, tapered, straight, or parallel. There are basically two kinds of screws, machine and wood screws. The two are manufactured from metal; although the machine screw carries steady diameter and combines with nuts while the wood screw is tapered and grabs the actual wood surface.

Raw Materials

Screws are usually made out of low to medium carbon steel wire, but hard and low-priced metals might be substituted, like brass, stainless steel, aluminum alloy or nickel alloys. Quality of the metal being used is of great importance so as to eliminate cracking. When a finish is applied to the screw, it is usually well-matched. Steel might be coated or plated with zinc, cadmium, nickel, or chromium for added protection Fastener material can be vital when selecting a fastener because of variations between materials in strength, corrosion resistance, brittleness, galvanic corrosion properties and obviously, cost.

 

modern toolsIn the past our ancestors were not so fortunate because they had to deal with hand tools. There were no power tools for them! Hardware hand tools are used by craftsmen in manual operations, such as chopping, chiseling, sawing, filing, forging, and more. Dating the oldest tools is still much of an uncertainty. There have been tools found in northern Kenya in the late 1960s which date to approximately 2,600,000 years old, and even older tools are likely to be discovered. Tools are one of the more accurate items that can be dated to reflect the development of mankind.

Here are some popular tools and their dates of creation:
