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 Defense Logistics Agency as a prime contractor under Total Small Business and full-and-open set-asides. The company competes in mechanical power transmission equipment, fasteners, bearings, and related hardware across two primary Defense Logistics Agency customer divisions with 148 prime awards carrying $8.9 million in combined potential value.

TNN Machining holds a single-owner structure (Partnership or Limited Liability Partnership) and operates exclusively as a prime contractor with no subcontractor history. The company's work footprint is 100% prime awards, concentrated in two NAICS categories: Bolt, Nut, Screw, Rivet, and Washer Manufacturing (32 awards) and Mechanical Power Transmission Equipment Manufacturing (31 awards), with additional volume in hardware manufacturing, ball and roller bearing manufacturing, and speed changer/gear manufacturing. Place of performance is Houston, Texas, with items delivered to Defense Logistics Agency consolidation and containerization points serving continental United States and overseas depots.

Customer concentration is narrowly focused on Defense Logistics Agency divisions. The Defense Logistics Agency Land and Maritime division accounts for 88 awards (59% of volume) and $6 million in combined potential value, while Defense Logistics Agency Aviation accounts for 58 awards (39% of volume) and $2.8 million combined potential value. The remaining two awards ($36 thousand) go to Defense Logistics Agency Troop Support (Hardware and Construction and Equipment). No awards have been issued by other federal agencies; the vendor's entire federal footprint is Defense Logistics Agency.

TNN Machining's parent vehicle position consists of seventeen single-award Indefinite Delivery Contracts issued by Defense Logistics Agency divisions between February 2026 and December 2025, each carrying a $250,000 to $350,000 ceiling. The three largest vehicles by task-order count are Indefinite Delivery Contract SPE7L326D60UZ ($331 thousand combined potential value, 3 task orders), SPE7L425D63BS ($141 thousand, 3 task orders), and SPE7L125D61HM ($46 thousand, 3 task orders). All parent vehicles are single-award IDIQs with one-year terms; none are Government-wide Acquisition Contracts or agency-wide vehicles. The vehicles procure groove pulleys, retainer seals, shouldered shafts, plain extended nuts, helical gears, spur gears, nonmetallic seals, universal join yokes, and related mechanical components under firm fixed-price delivery orders.

Representative prime awards span fasteners, gears, seals, and shafts. A $553,000 Total Small Business set-aside purchase order from Defense Logistics Agency Aviation (awarded January 27, 2026) procures piston rods (NSN 1650016513329) with completion by August 17, 2026. A $400,000 non-set-aside purchase order from Defense Logistics Agency Land and Maritime (October 20, 2025) covers retaining shaft plates (NSN 3040013450548) for completion by May 8, 2026. A $333,200 Total Small Business set-aside (October 23, 2025) procures a vehicular parts kit (NSN 2540010965023) with completion by October 23, 2026. Additional volume includes $164,520 for self-locking nuts (November 5, 2025), $162,456 for vehicular aligning rods (May 13, 2026), and $157,855 for bushings and sleeves (February 17, 2026). The company also holds recurring delivery orders for commodity items such as flat washers, socket head cap screws, close tolerance screws, and external release bolts, typically valued between $2,300 and $114,310 per order.

Activity has accelerated significantly. The company recorded 1 award in 2019, then 79 awards in 2025 and 68 in 2026 year-to-date (through July), reflecting recent onboarding into Defense Logistics Agency procurement channels. Awards completed in the next twenty-four months total 42 contracts with $1.5 million in combined potential value, creating material recompete exposure across the Land and Maritime and Aviation divisions. Combined dollars obligated stand at $4.1 million against $8.9 million in potential value, indicating 46% of the contract ceiling backlog remains available.

Set-aside posture splits roughly 60% Total Small Business (set-aside) and 40% full-and-open competition across the prime footprint, with the company securing awards across both categories. The vendor competes at the commodity-component level within Defense Logistics Agency's supply chain, manufacturing to National Stock Numbers and military specifications for distribution consolidation points rather than to named weapon systems or platforms. No teaming relationships or subcontractor history is present in the source data.
