About the company

Mack Boring & Parts Co, a small business Subchapter S corporation based in Somerset, New Jersey, supplies marine engine components and industrial parts to federal agencies as a prime contractor on purchase orders, delivery orders, and indefinite-delivery contracts. The vendor operates in a pure prime posture, holding approximately 3,488 prime awards across 29 customer agencies with no meaningful subcontracting footprint. Mack Boring & Parts Co competes predominantly under total small business set-asides, which account for a substantial portion of the vendor's active portfolio, though a material fraction of recent awards carry no set-aside designation.

Customer concentration is extreme. The top two customers by potential value account for 89% of the vendor's combined potential value: the Defense Logistics Agency Land and Maritime dominates with 2,008 awards (56% of all awards) and $39.8 million combined potential value, and the Department of Homeland Security US Coast Guard places 202 awards valued at $20.7 million. DLA Aviation adds 511 awards worth $2.9 million; the Department of the Navy Naval Sea Systems Command and Fleet Forces Command represent $1.8 million and $1.4 million respectively. This concentration reflects the vendor's narrow specialization: DLA Land and Maritime accounts for 56 percent of all awards and 53 percent of all dollars.

Mack Boring & Parts Co's capability portfolio centers on discrete industrial and marine engine components—fasteners (bolts, nuts, washers, springs), seals and gaskets, filter elements, fuel system parts (fuel pumps, injectors, metering pumps, filters), diesel engine sensors, actuators, solenoids, generators, hoses, and mechanical assemblies. Recent representative awards include a $138,000 delivery order from the Coast Guard on August 5, 2026, for a Yammer diesel engine under total small business set-aside (ultimate completion October 5, 2026); a $83,201 purchase order from the Bureau of Naval Personnel on June 1, 2026, for four Yammer engines, KM4A1 transmissions, and alternator kits (July 31, 2026 completion); and a $26,892.88 delivery order from DLA Land and Maritime on February 20, 2026, for a fuel metering pump under total small business set-aside (May 21, 2026 completion). The vendor holds at least 13 single-award indefinite-delivery contracts with DLA Land and Maritime and DLA Aviation, each carrying $350,000 ceilings and multiple-year terms through 2027. These IDCs cover filter elements, exhaust mufflers, electromagnetic actuators, outboard engines, generator sets, throttle solenoids, AC generators, electrical fuel pumps, and v-belts. Place of performance spans Somerset, Franklin Township, New Jersey, and subordinate DLA and Coast Guard depots across the Continental United States and overseas locations.

Activity has declined year over year from 305 awards in 2022 to 212 in 2026, with a notable drop in 2024 (167 awards). Combined potential value across all awards stands at $75 million with $29.6 million (39%) obligated to date. The recompete window shows minimal exposure: only four awards with combined potential value of $69 thousand face ultimate completion within the next twenty-four months, reflecting the vendor's reliance on standing IDC vehicles with one-year renewal cycles rather than large, front-loaded task orders. The vendor's award footprint is heavily weighted toward the past several years, with the oldest award dating to April 1981 and the most recent to August 5, 2026.

Category concentration confirms the marine engine and fastener specialization: Other Engine Equipment Manufacturing leads with 784 awards; Bolt, Nut, Screw, Rivet, and Washer Manufacturing accounts for 680 awards; Gasket, Packing, and Sealing Device Manufacturing holds 221 awards. Top PSC codes align: Packing and Gasket Materials (347 awards), Diesel Engines and Components (311 awards), and Engine Fuel System Components, Nonaircraft (295 awards) dominate.
