About the company
Mantissa Industries Inc., a small manufacturing business based in Holt, Michigan, specializes in the production of precision-engineered aerospace and defense metal components for the U.S. federal government. The company is an AS9100 and ISO 9001 certified manufacturer, demonstrating its commitment to quality standards required in the aerospace and defense industrial sectors. Since its registration in SAM.gov in March 2002, Mantissa Industries has established itself as a reliable supplier of complex metal parts and components to defense-related agencies, particularly the Defense Logistics Agency (DLA).
Mantissa Industries has received numerous federal contract awards totaling several hundred thousand dollars for the manufacture and delivery of specialized aerospace and defense components. The company's product portfolio includes mounting brackets, shafts and hooks, access covers and doors, shielding gaskets, spacer plates, mounting plates, rods and dampers, retainer inserts, and various other precision-engineered metal parts used in military equipment and aviation systems. These awards have been issued primarily by the Defense Logistics Agency through its Aviation and Land and Maritime divisions, with one notable contract from the U.S. Army Corps of Engineers. The contract awards range significantly in value, from less than $1,000 for individual delivery orders to over $558,000 for a large purchase order for spacer plates issued in February 2024. Set-aside designations include both Total Small Business set-asides and non-set-aside contracts, with the latter representing the majority of recent awards. Notable recent awards include a $16,427.93 purchase order for access covers from DLA Land and Maritime (September 2025), a $21,735.00 purchase order for mounting brackets (October 2024), and a $24,837.76 purchase order for access covers (August 2024). The company operates as a prime contractor on these awards, with work performed at its Holt, Michigan facility.
Mantissa Industries currently holds three active Indefinite Delivery Contracts (IDCs) with the Defense Logistics Agency, each valued at $250,000 and designated as Total Small Business set-asides. The first IDC, awarded by DLA Land and Maritime on September 19, 2024, covers the delivery of parts kits including tubes and related aerospace and defense components, with an ultimate completion date of February 25, 2025. The second IDC, awarded by DLA Land and Maritime on January 19, 2024, covers mounting plates and various metal components such as mounting brackets, shafts, hooks, and access covers, with an ultimate completion date of January 18, 2025. The third IDC, the oldest of the three, was awarded by DLA Aviation on March 4, 2021, covering shaft and hook components (National Stock Number 4610072030) for military aviation systems, with an ultimate completion date of March 3, 2026. Under these IDCs, DLA has issued numerous delivery orders and purchase orders ranging from under $1,000 to approximately $41,000. The IDC vehicle structure enables DLA to efficiently procure specialized aerospace and defense components through multiple orders throughout the contract performance period, with estimated procurement patterns of three to nine orders annually. These IDCs demonstrate DLA's confidence in Mantissa Industries' capabilities and commitment to utilizing small business vendors for critical military supply chain requirements.
