Our History

Our company was founded in 1954 as Seward Screw Products, Inc. by Dr. E.G. Falconer – the community physician at the time.

Dr. Falconer kept his medical practice in the small town of Seward from 1938 until 1985. His community-minded philosophy was instrumental in the growth and well-being of the town where he conducted his business and raised his family.

Seward Screw Products, Inc. was the result of his desire to create local job opportunities and to boost the economy of the town and its people.

About Us

The Transition from Medical Practice to Machining Provider

In 1954, the president of Greenlee Brothers, Inc. – one of Dr. Falconer’s peers – suggested that he use his business expertise and community standing to start his own company.

After deliberation, Dr. Falconer went on to purchase a new Greenlee automatic bar machine. A small building was erected and the machine was put to work.

A product of his resourceful and hard-working generation, Dr. Falconer would do quotations at night, deliver parts in the morning and meet with salesmen between his appointments with patients. His story was a perfect example of true American entrepreneurship, innovation and success.

A True Family-Owned American Machine Shop Built from the Ground Up

Since the early days of our machine shop, Seward Screw has remained a family-held corporation, carrying on Dr. Falconer’s vision and legacy. His daughter and two sons held various positions with the company during their working careers. His youngest son, Dale, served as President from 1984 until 2014. The company’s management team has continued to uphold the same principles and values that Dr. Falconer instilled in his family – to always put the customer’s needs first.

Integrating with Slidematic Precision to Lead the Industry in Quality Custom-Machined Components

In 2016, Seward Screw Products was purchased by the owners of Slidematic Precision Components and was reformed as Seward Screw, LLC. Slidematic is a third-generation, family-owned American manufacturing business based out of Rockford, Illinois.

They are a leading manufacturer of specialty cold headed products and a distributor of standard fasteners.

Slidematic saw complementary and synergistic opportunities for their company and Seward Screw. The two companies share numerous customers and, more importantly, share the same upstanding principles and values as Dr. Falconer: always put the customer’s needs first.

At Seward Screw, the Needs of our customers Come First

Throughout our 65+ years of constant growth and twelve building expansions, one thing hasn’t changed and will always remain true:
