TNN Machining Company, L.L.C.

TNN Machining Company, L.L.C., a Houston, Texas–based minority-owned, woman-owned, and Asian-Pacific American-owned small business, manufactures precision mechanical components and fasteners for the Department of Defense as a prime contractor across 117 federal awards structured predominantly as purchase orders and indefinite-delivery contracts without parent vehicles or subcontractor engagement.

TNN Machining operates as a limited liability partnership specializing in concrete mechanical components: socket head cap screws, self-locking nuts, grooved and flat pulleys, helical gears, spur gears and gearshafts, bearing housings and rings, shouldered shafts, bushings and sleeves, metallic tubes and pipes, seals and gaskets, fasteners, hydraulic and piston rods, and fluid passage bolts. The company competes across full-and-open and set-aside vehicles with roughly equal frequency. From the source's 117 awards, 51 carry Total Small Business set-asides and 28 carry no set-aside designation; the remainder do not have set-aside data in the award-level records. Recent representative contracts include a $553,000 purchase order from Defense Logistics Agency Aviation for ROD, PISTON, LINEAR A components (January 27, 2026), a $400,000 purchase order from DLA Land and Maritime for retaining shaft plates (October 20, 2025), and a $333,200 purchase order from DLA Land and Maritime for vehicular parts kits (October 23, 2025). TNN Machining also holds 16 single-award indefinite-delivery contracts ranging from $250,000 to $350,000 ceilings, including instruments for retainer seals, shouldered shafts, internal wrenches, plain extended nuts, nonmetallic seals, universal join yokes, helical gears, groove pulleys, and gearshafts—all awarded by Defense Logistics Agency Land and Maritime or Aviation divisions between July 2025 and April 2026.

Customer concentration is extreme and cohesive. Defense Logistics Agency Land and Maritime dominates at 74 awards ($5 million combined potential value, 68% of total), and Defense Logistics Agency Aviation follows with 41 awards ($2.3 million, 31% of total). DLA Troop Support accounts for two awards totaling approximately $36,000. This vendor has zero subcontract history and works only as a prime. The source identifies four distinct customer agencies; two of those are DLA subdivisions of the same parent organization, rendering the effective customer base a single entity—Defense Logistics Agency.

Activity trajectory shows recent explosive growth. The source records one award in 2019, then a gap until 2025, when 79 awards were registered. In 2026 through mid-April, the vendor has secured 37 additional awards. Thirty-eight awards (combined potential value $1.4 million) reach ultimate completion within the next twenty-four months, representing moderate recompete exposure against the backdrop of high recent velocity. The vendor's typical award cycle consists of transactional purchase orders for standardized mechanical components (bolts, nuts, gears, pulleys, shafts, seals) with firm fixed pricing, 3–12 month delivery windows, and DLA distribution consolidation and containerization points serving CONUS and OCONUS defense depots.

TNN Machining's product footprint concentrates in mechanical power transmission equipment (27 awards) and fastening hardware (bolt, nut, screw, rivet, washer manufacturing: 25 awards), with secondary clusters in ball and roller bearing manufacturing (9 awards), general hardware (8 awards), and gear manufacturing (8 awards). PSC coding reflects parallel concentration: Miscellaneous Power Transmission Equipment leads with 18 awards, followed by Gears, Pulleys, Sprockets, and Transmission Chain (17 awards) and Nuts and Washers (12 awards). Across all awards, the vendor delivers standardized or lightly customized components manufactured to military specifications and National Stock Numbers, with delivery obligations tied to DLA consolidation logistics.

The vendor registered in SAM in October 2018 according to multiple award narratives. Combined potential value across all 117 awards stands at $7.4 million, with $3 million obligated (40% burn rate), indicating a vendor in early but rapid scaling phase within DLA supply base. No evidence of teaming, subcontracting, or participation in larger IDIQs or GWACs appears in the source material.
