About Horst Engineering & Manufacturing Co
Horst Engineering & Manufacturing Co, doing business as Horst Engineering, is a precision-components manufacturer based in East Hartford, Connecticut, that supplies small-batch machined aerospace hardware and mechanical components to the Defense Logistics Agency as a prime contractor on full-and-open purchase orders, with no set-aside activity. The company is a for-profit Subchapter S Corporation and parent entity to Sterling Machine Company, Inc., a subsidiary also engaged in precision manufacturing.
Horst Engineering's federal work centers on high-tolerance machined components for defense applications: bearing washers, thrust components, piston and valve assemblies, hinge pins, close-tolerance screws, straight headless pins, adaptor fittings, actuating cylinders, fluid flow restrictors, spacers, and sleeves. Representative recent awards include a $132,105 firm fixed-price purchase order from DLA Land and Maritime for piston and valve components (116 units plus one additional unit with delivery through March 2029), a $49,460 order from DLA Aviation for hinge pins and panel components (May 2026 delivery), a $44,800 order from DLA Land and Maritime for pistons and valves (December 2027 completion), and a $50,901 purchase order from DLA Land and Maritime for 65 actuating cylinders under a total small business set-aside (completed November 2024). All production occurs at the East Hartford facility.
Customer concentration is heavily skewed to Defense Logistics Agency divisions across five sub-organizations. The top five DLA customer units account for 94% of the 550 total awards in the source and represent the entire customer base: DLA Troop Support Construction and Equipment leads with 188 awards totaling $1.6 million combined potential value, followed by DLA Troop Support Hardware (124 awards, $519 thousand), DLA Aviation (107 awards, $1.3 million), DLA Land and Maritime (69 awards, $700 thousand), and DLA corporate (28 awards, $100 thousand). The award portfolio reflects consistent small-dollar purchase orders rather than large IDIQs or blanket agreements; combined potential value across all 550 awards totals $10.1 million, but only $8.1 million has been obligated.
Horst Engineering's parent contract vehicles are small IDIQs issued directly by DLA Troop Support. The five highest-activity vehicles are Indefinite Delivery Contract SPM5AZ07D4864 (66 task orders, $819 thousand combined value), SPM5AZ07D4827 (33 task orders, $207 thousand), SPM5AZ08D0045 (16 task orders, $147 thousand), SPM50004D0275 (7 task orders, $70 thousand), and SPE4A715D5086 (5 task orders, $40 thousand). These are not government-wide vehicles; they are agency-level DLA procurement instruments. The company also holds a five-year IDC from DLA Aviation valued at $250,000 for the supply of linear-rotary rollers under a total small business set-aside.
Recent activity has been sporadic: four awards in 2022, two in 2023, five in 2024, seven in 2025, and one in the first quarter of 2026. Only one award ($45 thousand combined potential value) faces completion within the next twenty-four months, reducing near-term recompete exposure. The source names one subcontract relationship: Horst supplies GE Aviation Engine Hardware components to General Electric Company on a performance-based logistics arrangement (sub-award dated February 2025). The portfolio is dominated by fastener and hardware NAICS codes — Bolt, Nut, Screw, Rivet, and Washer Manufacturing (188 awards) and Hardware Manufacturing (163 awards) — with secondary exposure to ball and roller bearing manufacturing and fabricated pipe and pipe fitting manufacturing. PSC-level work concentrates on nails, machine keys, and pins (141 awards), screws (81 awards), and studs (55 awards).
