What MacLean-Fogg Company does
MacLean-Fogg Company is a fourth-generation, family-owned American industrial manufacturer founded in 1925 and headquartered in Mundelein, Illinois. The company designs, engineers, and produces precision components and assemblies — primarily engineered fasteners, cold-formed parts, precision machined components, threaded products, injection-molded engineered plastics, gravity flow storage, and rubber/plastic dipped parts — across more than 14 manufacturing facilities in the United States. Its operational portfolio is organized under four operating brands: MacLean-Fogg Component Solutions (the core automotive and power utility fastener business, including supply of one lock nut specification to North American railroads), Mallard Manufacturing (gravity flow storage and material handling), OMCO (custom rubber and plastic dipping and cold-formed forming), and Threadstrong (threading and fastening solutions). Customers are concentrated in B2B enterprise verticals: automotive OEMs and Tier 1 suppliers, electric power utility and transmission companies, aerospace and defense contractors, and general industrial manufacturers requiring tight-tolerance, qualified components.
The company's go-to-market is direct enterprise sales to engineering and purchasing departments at OEMs, Tier 1s, and utilities, backed by quote-based pricing tied to specifications, volumes, and multi-year contracts. Primary customer segments are vertical: automotive and power utility are flagged as primary, with aerospace/defense and broader industrial manufacturing as secondary. Manufacturing processes combine capital-intensive forming (cold heading, stamping), subtractive machining (CNC, screw machines), and plastics processing (injection molding, extrusion, dipping), supported by in-house tooling and thread rolling capabilities. Certifications in scope include ISO 9001 for quality management and GDPR/CCPA/PIPEDA for privacy compliance.
Revenue is generated through B2B hardware sales of custom-manufactured components under contractual terms; pricing is not publicly disclosed. The business is privately held under founding-family ownership with no recorded external funding rounds, no institutional investors, and no parent company. Recent strategic activity has emphasized inorganic expansion: the company acquired Mallard Manufacturing in May 2024 to enter material handling, and announced the acquisition of OMCO in February 2026 to broaden forming and dipping capability. Management remains founder-family led, with Duncan MacLean serving as President & CEO.
