MacLean-Fogg: A Century of Reinvention in American Manufacturing

MUNDELEIN, IL – January 27, 2026 – In an era where corporate longevity is measured in decades, if not years, MacLean-Fogg stands as a monument to endurance. The fourth-generation, family-owned manufacturer celebrated its 100-year anniversary in 2025, joining an elite club of American companies—estimated at less than 0.5% of all U.S. businesses—that have survived for a century. Its journey from a single-product startup serving railroads to a global powerhouse in engineered components offers a masterclass in resilience, adaptability, and the enduring power of a long-term vision.

Founded in 1925 by the grandfather of current Chairman Barry MacLean, the company was built on a simple yet profound premise. "He wanted to build a business around making something," MacLean shared. That desire to make has been the throughline of a story that mirrors the evolution of American industry itself, navigating economic booms, busts, and technological revolutions by consistently returning to its core identity as a problem-solver and innovator.

A Century Built on Reinvention

MacLean-Fogg's story began with the arteries of American commerce: the railroads. The company’s first major products, like the Water Tight Bolt and the patented Lock Tight Floor Clip, were designed to solve specific fastening challenges for the rail industry. This initial focus on creating robust, reliable components set a precedent that would define the company for the next hundred years. As the 20th century progressed, the company became synonymous with its iconic “Whiz-Lock” nuts, a testament to its innovative spirit in the fastener world.

However, true longevity required looking beyond the rails. As industries shifted, so did MacLean-Fogg. The company astutely expanded its engineering discipline into burgeoning industrial and automotive markets, applying its expertise in material forming and fastening to a new set of complex challenges. This was not a single pivot but a continuous process of evolution. "MacLean-Fogg is always reinventing itself," explained Kristin Malbasa, Executive Vice President of Human Resources. "Being entrepreneurial is in our DNA."

This entrepreneurial spirit is evident in the company's strategic expansion of its capabilities. It has mastered a wide array of manufacturing processes, including hot forging, cold forming, deep drawing, and advanced machining. This diversification of skills allowed the company to stay relevant and indispensable, even as its end markets underwent dramatic transformations. The pattern established across generations remains its guiding principle: identify problems, engineer solutions, and execute with disciplined excellence.

The Long Game of Family Ownership

In a business world often criticized for its obsession with quarterly earnings and short-term gains, MacLean-Fogg’s status as a privately held family enterprise provides a powerful competitive advantage. This structure allows the leadership to prioritize sustainable performance, cultivate lasting customer relationships, and make strategic investments that strengthen the organization for future generations.

This long-term mindset permeates the company culture. It’s a philosophy that values people as its most critical resource, fostering an environment of respect and mutual trust. Retired employees recall this unique culture with clarity. "It all goes back to that family theme," said Denny Zalar, a retired employee. "Be in it for the long term. Treat people with respect." This sentiment is echoed by fellow retiree Steve Whiting, who noted, "You felt like you were part of something. You weren't just doing a job. You were building something bigger."

This people-centric approach is not just anecdotal. The company backs its philosophy with concrete action, recently releasing its first Sustainability Report, which details significant investments in employee development, community support, and environmental stewardship. Initiatives include awarding nearly a million dollars in student scholarships and providing 100,000 meals to local communities, demonstrating a commitment that extends well beyond the factory walls. This long view, focused on building strong teams and doing the right thing, is presented not as a cost, but as the fundamental driver of strong results.

From Rails to Robotics: Engineering the Future

While its history is foundational, MacLean-Fogg’s focus is firmly on the future. The company’s commitment to operational excellence has evolved from simple quality control to a deep integration of Lean manufacturing principles and advanced technologies. This ongoing investment in modernization ensures consistent quality, reliable delivery, and competitive costs for an increasingly demanding global market.

Nowhere is this future-focus more apparent than in its strategic growth initiatives. The 2024 acquisition of Mallard Manufacturing, a leader in gravity flow solutions for warehousing and distribution, represents a significant step in strengthening MacLean-Fogg’s industrial portfolio. The move diversifies its market presence while aligning perfectly with its core identity as a maker of engineered components. "We believe our partnership with MacLean-Fogg will enable us to continue growing the business and serving our customers with innovative, high-quality solutions," said Kevin Risch of the Mallard team at the time of the acquisition.

The company is also at the forefront of the next manufacturing revolution: additive manufacturing. Through its MacLean Additive division, it is developing 3D-printable hard ferrous metallic alloys and has delivered game-changing 3D-printed tool inserts to major automotive players like Toyota Europe. This investment in cutting-edge technology demonstrates that the company's innovative spirit is as vibrant today as it was a century ago.

As it embarks on its second century, MacLean-Fogg is anything but complacent. With a clear strategy to strengthen its core markets while expanding into new industries, the company is positioning itself for another 100 years of success. "For the first time in a long time, we're on offense," declared President and CEO Duncan MacLean. "It's like we're a brand-new company with a strong base, building for the next 100 years." This offensive strategy involves continued investment in forming and fastening innovation, modern equipment, and enhanced manufacturing capabilities, all while nurturing the people-centric culture that brought it this far. To commemorate its journey, the company has launched a “100 Stories of Legacy” video series, capturing the personal stories that have collectively built a century of manufacturing excellence.
