ARGO SPRING MANUFACTURING CO., INC.

ARGO SPRING MANUFACTURING CO., INC. specializes in the precision manufacturing of springs, fasteners, and forged metal components for defense and aerospace applications. The company’s core expertise lies in spiral torsion springs, retaining springs, and assembled spring mechanisms, produced using nonferrous forging and high-tolerance stamping techniques. Their technical capabilities extend to the production of bolts, nuts, screws, rivets, and washers compliant with military specifications, with deep experience in material selection, heat treatment, and surface finishing for high-stress environments. The contractor demonstrates consistent proficiency in custom-engineered metal components requiring tight tolerances, consistent load characteristics, and durability under extreme operational conditions—making them a trusted supplier for mission-critical mechanical systems. The company maintains a longstanding relationship with the Department of Defense, supplying precision-engineered metal components across land, maritime, and aviation domains. Their work supports maintenance, repair, and overhaul programs for military vehicles, aircraft systems, and ordnance assemblies, often fulfilling urgent requisitions for replacement parts and specialized hardware. While DLA Land and Maritime is a frequent contracting partner, the majority of their engagements stem directly from DoD program offices requiring reliable, low-volume, high-reliability fabrication. Primary industry focus centers on spring manufacturing (NAICS 332613), bolt and nut production (332722), and nonferrous forging (332112), positioning the company as a niche supplier of mechanically critical metal components for defense systems. They serve the defense industrial base with a focus on replaceable, high-cycle mechanical parts that demand repeatability and material integrity. Argo Spring Manufacturing Co., Inc. is a small, privately held business based in Norwalk, California, with no federal certifications on record. Their geographic presence is localized but strategically aligned with defense supply chains on the West Coast, supporting just-in-time delivery needs for government contractors and military depots.
