J. BYL HOLDINGS, LLC

J. BYL HOLDINGS, LLC specializes in precision machining and fabrication of mission-critical metal components for defense and aerospace applications. The company produces custom hardware, brackets, sleeves, collars, and shaft components using advanced machine shop techniques, with demonstrated expertise in aluminum and fabricated metal parts. Their work involves tight-tolerance machining, surface finishing, and assembly of complex subsystems for military and space systems, including mounting hardware, mechanical power transmission elements, and specialized aerospace fittings. Technical capabilities center on CNC machining, metallurgical compatibility, and adherence to military and aerospace specifications for durability and performance under extreme conditions. Their niche lies in low-volume, high-precision production of non-standard components where dimensional accuracy and material integrity are paramount. The contractor maintains a strong relationship with the Department of Defense, supplying engineered metal parts for vehicle, aircraft, and equipment systems. They have also delivered components to NASA, indicating experience meeting the rigorous quality and documentation standards of spaceflight applications. Their work for these agencies consistently involves mission-essential hardware requiring traceability, material certification, and strict compliance with technical drawings and inspection protocols. Industry focus is concentrated in hardware manufacturing (NAICS 332510), machine shops (332710), and miscellaneous fabricated metal product manufacturing (332999), with additional activity in motor vehicle parts and mechanical power transmission equipment. This positions J. BYL HOLDINGS as a specialized supplier for defense and aerospace supply chains requiring custom, small-batch fabrication rather than mass production. As a small business structured as a 2L entity based in Belding, Michigan, the company operates with a lean, agile model focused on responsive, high-quality manufacturing. While no formal government certifications are listed, their consistent delivery of defense-critical components suggests established quality systems aligned with AS9100 or ISO 9001 standards. Their geographic location supports regional defense and aerospace logistics networks.
