MANTISSA INDUSTRIES INC

Mantissa Industries Inc. specializes in the precision manufacturing of mission-critical metal components for defense and aerospace systems, with deep expertise in fastener systems, aircraft subsystems, and ordnance accessories. The company produces high-integrity mounting brackets, sealing gaskets, tube kit components, shafts, and studs engineered to stringent military specifications, often supporting first-article testing and low-volume, high-reliability production runs. Their technical capabilities span cold and hot forging, precision stamping, threading, and surface treatment processes, with a focus on materials compatibility and environmental resilience under extreme operational conditions. A key differentiator is their ability to deliver complex, small-batch assemblies with tight tolerances for legacy and next-generation platforms, ensuring seamless integration into existing defense systems. The contractor maintains an exclusive relationship with the Department of Defense, supplying components across aviation, land, and ordnance domains. Their work supports aircraft subsystems, weapon system integration, and structural fastening applications, consistently fulfilling requirements for ruggedized, non-corrosive, and high-stress components used in combat and support platforms. Mantissa’s primary industry focus lies in hardware manufacturing (332510), fastener production (332722), aircraft parts (336413), and ordnance accessories (332994), positioning them as a niche supplier for defense contractors requiring certified, non-commercial off-the-shelf metal components. They serve as a trusted source for specialized parts that cannot be sourced through commercial channels due to performance, security, or obsolescence constraints. As a small, privately held manufacturer based in Holt, Michigan, Mantissa Industries operates as a Tier 2/3 supplier with no federal certifications, relying instead on proven technical rigor and consistent delivery to sustain long-term DoD engagements. Their geographic location supports efficient logistics to major defense hubs in the Midwest and Great Lakes regions.
