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:

Check out the Riveters in action at the FRC World Championship. Their unit is the pieces with the polka dot arms.  So come and watch the Mercy High School robotics team in action.

riveters gov snyder picMichigan has the most FIRST Robotics teams of any state in the country, but teams from an all-girls High School are rare. The team performed in two district competitions (Southfield High School and Centerline High School) to earn enough points to qualify for the Michigan State Championship. They ended up ranked 53rd of a field of 411 robotics teams throughout the state. This is a remarkable feat considering this is only their second year of competition.

The Riveters were the highest placing all-girls High School in the State of Michigan.  The team sponsors include Autodesk, Fiat Chrysler Automotive, Articulus, Inc., Ford Motor Company, MetroBolt and Fastener, and Wright Beamer, LLC

In Process Control, Optical Comparator, Hardness Testing & Product Testing

six sigmaThe next time you purchase any product from Metro Bolt & Fastener, remember this; There are several quality test methods that are performed prior to your purchase. But first let's define what Metro Bolt & Fastener means when we say "Quality Control".

Quality, is a conformance with products' specifications. Control, is consistency with controlling the variables to ensure there are no defects. When we combine the two, Quality Control is a process of implementing product design dimensions and tolerances to produce products that are of consistently good quality within the design parameters. How do we ensure this happens? Lets' start here.
