STEM stands for Science, Technology, Engineering and Mathematics. It is a small acronym but in no way insignificant.

If we question ourselves about the importance of STEM in our daily lives and take time out to really reflect on the implications of the disciplines encompassed by those four letters, we will admit readily that the whole precept of civilization is one that is supported by STEM.

From the understanding of the solar eclipse as a celestial phenomenon and not the wrath of whimsical gods to the towering skyscrapers and the busy, life-changing labyrinth of the internet, our advancement is hinged on how we understand our surroundings, translate our visions into tangible blueprints and execute the blueprints as per best practices to produce robust structures, theories and paradigms. And these activities need to leverage STEM – heavily!


Tackling the pragmatic first, according to a pronouncement made by the United States Department of Labor, eight out of the ten most lucrative careers and valued employees are closely related to STEM disciplines. The Department of Commerce has unearthed substantial discrepancies and inequality between the wages earned by STEM employees and those from non-STEM backgrounds. For example healthcare workers with associate degrees to doctor of medicine, earn a full 20% more over their lifetime than their peers who hail from non-healthcare niches.

Not only does a STEM centric education increase the quality of life because of better compensation, a child interested in Science and Technology is likelier to land a job straight out of college because STEM occupations grow at the rate of 17%, almost double that of non-STEM sectors.

Over 2008 to 2014, biomedical engineers earned $77,400 as median wage and this average applies to the entire nation! It is no small wonder that other jobs boasting high annual incomes also belong to the STEM paradigm.


Moving away from the strictly practical considerations, STEM and its popularity is also fundamental to the growth and development of the global economy. From semi-conductors which can function at room temperature to an effective cure to the life threatening curse of cancer, without science, technology and engineering, these leaps into the next generation of advancements and monetization is not possible.

US lags far behind its Asian and European counterparts where the adoption of STEM careers is concerned. A US News Survey says that only 1 in 4 graduates in the country belong to STEM educational pursuits. Even though the demand for STEM skills is the highest, a very small percentage of students who hail from science actually choose to stick to the field and seek gainful employment in the concomitant industries and sectors.

If progress is to be made and maintained by the citizens of the country, STEM has to be encouraged in all its forms. Companies must undergo a mind-set shift and look to invest in STEM endeavours instead of ‘brain draining’ other nations to get relevant jobs done.

Keystone Threaded Products wholeheartedly supports STEM and its pursuit.  As suppliers of threaded bars, nuts and other custom made high quality components, it is dedicated in its commitment to engineering efforts and the benefits to be realized from an education in science.

Ohio Manufacturing Facts

Ohio is powered by manufacturing. Ohio manufacturing is responsible for almost 17% of Ohio’s Gross Domestic Product and contributes to the quality of life in Ohio by providing:

  • More than 600,000 jobs for Ohio workers
  • An annual payroll of more than $33 billion, the highest total annual wages of any non-government economic sector
  • More than $46 billion in products to more than 216 countries and territories
  • A safer environment through decreased emission and increased recycling

In 2009, about 10% of all Ohio workers were employed in manufacturing. Almost 50% of Ohio manufacturing firms employ fewer than 10 people, while 0.3% employs more than 1,000.

Manufacturing is the largest of the 20 sectors of Ohio’s economy with 16.7% of total output in 2010; durable goods were 9.8 percent and non-durable goods were 6.9 percent of output.

Ohio’s manufacturing sector produced $80.0 billion worth of goods in 2010, ranking it fifth in the nation after California, Texas, Illinois and North Carolina.

The average annual earnings of Ohio workers on manufacturing payrolls in 2010 were $53,281.

In the year 2011, Ohio was ranked first nationally in new site selections and the manufacturing was involved in 52% of the new site selections. Transportation equipment, fabricated metals, chemical and machinery manufacturers were the leading manufacturing investors in 2011.

In the year 2011, Ohio ranked third in manufacturing employment nationally, with 5.4% of manufacturing jobs nationwide. Ohio had 25,000 more manufacturing jobs in 2011 than in 2009. Also, 12.5% of Ohio nonfarm employees worked in manufacturing, compared to the national percent of nonfarm employees in manufacturing of 8.9%. In 2011, Ohio was the ninth largest exporting state and in the same year they exported $46.4B in goods to 216 countries and territories.

Ohio had 307,900 jobs linked to manufactured exports in 2009, 7.1% of Ohio’s private sector employment. U.S. manufactured-exports linked employment represented 4.8% of private sector employment.

Threaded Bars in Heat Exchangers

Keystone Threaded Products

At Keystone Threaded Products, we manufacture quality roll threaded products, and we use our threaded bars in heat exchangers. We specialize in the production of roll threaded products including acme threaded bars, precision acme components such as acme round nuts, acme cylinder nuts and mounting flanges. We work with a variety of metals, including various grades of carbon steel, alloy steel, heat treated metals and stainless steel. We also work with bronze, aluminum brass, titanium, alloys and exotics.

When it comes to selecting the right heat exchanger, the process consists of a trade-off between the overall heat transfer measurements, which affect the pump head on the HVAC system. It also influences other factors including the pressure drop and surface area.

Generally, low pressure drop increases the surface area of the heat exchanger, which will then increase the unit’s initial cost. The key to choosing the proper heat exchanger is to find the smallest model with the same type of plate corrugation capable of handling the flow during both the summer and winter.

The next step in choosing the right heat exchanger is to simulate it with the largest surface area and plate corrugation type. This can be done by selecting the unit with the temperatures and flow profiles of the other season to obtain the duty value required for the season. The best solution is achieved when temperature, flow and pressure drop are all within the acceptable limits. Be sure to keep all of this in mind when looking for a heat exchanger so that it’ll last in the long run.
