MARION PRECISION MACHINING LLC

Marion Precision Machining LLC specializes in the precision manufacturing of critical metal components for defense applications, with deep expertise in threaded hardware, pins, plugs, and sleeve bearings. The company produces high-tolerance fabricated metal parts including threaded standoffs, straight and tapered pins, and machine-threaded plugs, utilizing advanced CNC machining, thread rolling, and surface finishing techniques to meet stringent military specifications. Their technical proficiency extends to the production of mechanical power transmission elements and specialized bearing assemblies, demonstrating capability in material selection, dimensional accuracy, and surface integrity required for mission-critical defense systems. What sets them apart is their consistent delivery of small-batch, high-reliability components with tight tolerances, often for legacy or niche military platforms where precision and repeatability are non-negotiable. The contractor maintains an exclusive focus on the Department of Defense, supplying precision-fabricated metal components across multiple program areas including ground vehicle systems, ordnance assemblies, and aircraft subsystems. Their long-standing relationship with DoD reflects a proven track record in fulfilling urgent, low-volume requirements for specialized hardware that supports maintenance, repair, and overhaul operations. Industry focus centers on NAICS 332510 (Hardware Manufacturing) and 332999 (Miscellaneous Fabricated Metal Product Manufacturing), where they serve as a niche supplier of non-standard, mission-specific metal components. Their market positioning is that of a precision fabricator for defense logistics and sustainment, filling gaps where commercial suppliers cannot meet military-grade requirements. Marion Precision Machining LLC is a small, privately held business based in Columbia, South Carolina, with no federal certifications on record. Their geographic footprint is localized, but their impact is national through direct DoD supply chains, positioning them as a reliable, agile source for specialized metal fabrication needs within the defense industrial base.
