Argo Spring Manufacturing Co., Inc.

Argo Spring Manufacturing Co., Inc., a veteran-owned small business based in Norwalk, California, manufactures helical compression, extension, torsion, flat, and leaf springs, along with spring assemblies and specialized fastening components for the U.S. Department of Defense as a prime contractor exclusively, with 100% of recent awards issued as prime contracts or indefinite delivery vehicles rather than subcontract positions.

The company operates as a for-profit manufacturer under primary NAICS code 332613 (Spring Manufacturing) and competes predominantly under small business set-asides, particularly Total Small Business designations across DLA contract vehicles. Argo Spring's customer footprint concentrates heavily within Defense Logistics Agency divisions. The Defense Logistics Agency Troop Support Hardware leads by award count with 556 awards valued at $7.4 million combined potential value, while DLA Land and Maritime follows with 339 awards at $6.4 million. DLA Troop Support Construction and Equipment accounts for 153 awards valued at $2.6 million. These three DLA divisions comprise roughly 90% of Argo Spring's recent award activity. The Defense Logistics Agency Aviation division and Naval Sea Systems Command round out the major customer set. Within the past year, Argo Spring has secured seven active single-award indefinite delivery contracts with DLA Land and Maritime—five valued at $350,000 each (awarded January 2026, January 2026, January 2026, November 2025, and December 2025) and two valued at $250,000 each (awarded December 2025 and June 2025)—providing flexible procurement mechanisms for helical compression and torsion springs across multiple national stock numbers. The company also maintains earlier IDC vehicles through October 2024 and beyond, enabling recurring delivery orders.

Argo Spring's activity has grown significantly. The past five years show expansion from 41 awards in 2022 to 98 in 2025, with 41 awards recorded in 2026 year-to-date. The combined potential value across all 1,298 prime awards stands at approximately $18 million, with $8.2 million obligated as of the snapshot date, representing 45% of potential value. Within the next twenty-four months, seventeen awards (combined potential value $130 thousand) face ultimate completion and potential recompete exposure.

Representative work includes more than 150 firm fixed-price purchase orders and delivery orders from DLA Land and Maritime for helical compression springs (multiple national stock numbers), helical torsion springs, flat springs, leaf springs, retaining clips, lock pins, and spring assemblies, each ranging from under $1,000 to over $71,000 per order. Argo Spring also fulfills orders from Naval Sea Systems Command for safety pins, initiator springs, piston locking springs, and retaining springs, and from DLA Aviation for lock pins, retaining rings, and specialty spring components. The company holds one subcontract relationship: a $50 thousand nominal subcontract with ES3 Prime Logistics Group Inc. for helical torsion springs (National Stock Number 5360012507459) awarded in February 2024, representing minimal sub-engagement relative to its prime footprint.

The source notes that Argo Spring Manufacturing holds multiple indefinite delivery contracts with DLA Land and Maritime, each historically valued up to $250,000, and has served as a subcontractor to Raytheon Company and major defense suppliers. The company's veteran-owned small business status and demonstrated reliability in meeting military specifications position it as an established supplier within the defense logistics supply chain, with procurement activity concentrated on equipment maintenance and readiness support across continental and overseas DLA depots.
