In 1925, MacLean-Fogg began as a small, family-owned manufacturer serving the railroad industry. One hundred years later, the company remains a global supplier of precision fasteners and engineered metal components, deeply embedded in the automotive and industrial sectors and closely connected to the gear industry.
Reaching a century in manufacturing requires more than endurance. It demands adaptation, disciplined execution, and a willingness to evolve with changing technologies and markets. For MacLean-Fogg, reinvention has been a defining characteristic across four generations of family leadership.
Today, the company operates 12 locations globally and employs about 2,100 people. Duncan MacLean serves as fourth-generation president and CEO, continuing a leadership legacy that began with his great-grandfather. Barry MacLean, third-generation leader and former president and CEO, now serves as Chairman of the Board and remains actively involved in guiding long-term strategy.
From Railroad Locknuts to Tier 1 Automotive Supplier
MacLean-Fogg’s origins lie in producing locknuts and fasteners for rail applications. As transportation technology shifted and automotive manufacturing accelerated, the company recognized that remaining static would limit its future.
Over time, MacLean-Fogg expanded its expertise in cold forming, precision machining, and engineered assemblies. Through strategic growth and acquisitions, the company strengthened its capabilities in precision-machined components and gear-related applications, positioning itself within the broader gear supply chain.
Today, MacLean-Fogg is a Tier 1 supplier to major automotive manufacturers, providing high-volume, safety-critical fasteners and engineered components that support drivetrain and motion systems. The company also produces precision gear blanks and near-net gear components that serve as the foundation for finished gears used in automotive, agricultural, heavy equipment, and industrial applications.
These components play a critical role upstream in the gear-manufacturing process. By delivering tight tolerances and consistent material properties at scale, MacLean-Fogg helps downstream gear manufacturers reduce machining time, improve material efficiency, and enhance overall system performance.
Engineering Partnership and Early Collaboration
A central element of MacLean-Fogg’s longevity is its consultative engineering model. Rather than functioning solely as a transactional supplier, the company engages early in product development conversations to address manufacturability, performance, and cost from the outset.
“We would not have lasted 100 years by simply repeating what worked in the past,” said Nick Stauffer, Organizational Development Manager at MacLean-Fogg. “Our strength has always been our ability to transform. We stay relevant by bringing engineering expertise to the table early, solving the right problem first, and then building the process around that solution.”
This approach is particularly important in safety-sensitive markets. Fasteners and gear-related components used in modern vehicles and industrial equipment must meet rigorous quality and durability standards. MacLean-Fogg’s emphasis on disciplined process control and continuous improvement has enabled it to support customers across multiple product generations and evolving performance requirements.
Core Values That Drive Performance
While markets and technologies have changed, MacLean-Fogg’s core values have remained consistent. “Integrity, People, Customers, and Stewardship” form the foundation of the company’s culture and decision-making.
Investment in people has long been a priority. Under Barry MacLean’s leadership, the company was an early advocate of tuition reimbursement and structured development programs. That commitment continues today under Duncan MacLean’s leadership, with ongoing investment in workforce development, leadership training, and advanced manufacturing capabilities. Long-tenured technical expertise across the organization provides continuity in process knowledge and customer relationships. In an industry facing skilled labor shortages and rapid technological change, that stability remains a competitive advantage.
Strategic Diversification and Future Growth
Although automotive remains a core market, MacLean-Fogg continues to expand into adjacent industrial sectors, applying its precision forming and machining expertise to new applications. Recent strategic acquisitions have broadened the company’s engineered solutions portfolio while reinforcing its operational discipline.
This diversification supports long-term stability while leveraging existing strengths in high-volume, precision metal manufacturing.
As the company marks its 100-year anniversary, it reflects not only on its history but also on the technological shifts shaping the future of gearing and motion systems. Electrification, lightweighting, automation, and advanced materials will continue to redefine drivetrain design and manufacturing processes. MacLean-Fogg intends to remain part of those engineering conversations, contributing precision components that enable next-generation performance.
Celebrating a Century and Looking Ahead
To commemorate its centennial, MacLean-Fogg conducted a year-long “100 Years of Stories” initiative featuring employees, customers, and partners whose experiences reflect the company’s impact across generations. The celebration culminated in a formal gala honoring both the company’s history and its forward-looking strategy.
The milestone serves as both a reflection and a commitment.
After 100 years, MacLean-Fogg’s position in the gear and fastener industries rests on disciplined manufacturing, engineering partnership, and family stewardship. Under fourth-generation leadership, the company continues to evolve while maintaining the principles that sustained it for a century.
In manufacturing, longevity is earned through relevance. MacLean-Fogg’s century of precision manufacturing demonstrates that the ability to adapt, invest, and engineer for the future remains its defining strength.
