About the company
Mcmaster-Carr Supply Co sells industrial hardware, tools, plumbing supplies, electrical components, and maintenance-repair-operations (MRO) materials to the federal government as a prime contractor on full-and-open purchase orders with no small business set-aside posture. The company is a for-profit organization headquartered in Elmhurst, Illinois, with no disclosed minority ownership or SBA certifications; it operates across 128 distinct federal customer agencies through a sprawling purchase-order footprint.
Mcmaster-Carr's federal capability set is defined almost entirely by transactional MRO supply — individual fasteners, wire, seals, filters, plumbing fittings, and hardware components ordered by the unit or in small batches. The vendor's award portfolio spans 5,527 total awards (99.7% prime) with a combined potential value of $3.7 million and combined obligated dollars of $6.8 million, reflecting a high-volume, low-dollar-per-order profile characteristic of a commercial off-the-shelf supplier. Recent concrete examples include a $13,940.72 purchase order from the Federal Correctional Institution La Tuna in February 2026 for fuses, grommets, nuts, rivets, screws, fire extinguishers, and electrical tape; a $45,256.28 order from the Bureau of Overseas Building Operations in June 2025 for plumbing waterline supplies; a $22,348.89 Army Materiel Command award in August 2023 for hinges to Rock Island Arsenal; and recurring small-dollar orders from Naval Supply Systems Command and Defense Logistics Agency Land and Maritime for cable assemblies, gaskets, o-rings, and fasteners.
Customer concentration sits with the Federal Bureau of Prisons and the Navy. The top five funding agencies by award count cover 26% of all awards, led by the Department of the Army with 490 awards ($84 thousand combined potential value) and the Navy's Pacific Fleet Forces with 292 awards. When ranked by combined potential value, the Bureau of Prisons Federal Correctional Institution Gilmer dominates with 158 awards valued at $372 thousand, followed by Naval Supply Systems Command with 104 awards worth $267 thousand. The disparity between volume and dollar rankings reflects Mcmaster-Carr's role as a low-cost tactical supplier to institutional customers (correctional facilities, naval supply depots) that place frequent small orders alongside higher-value recurring purchases from Navy logistics commands. GSA Federal Acquisition Service places 203 awards, signaling a presence on commercial supply vehicles.
Mcmaster-Carr operates primarily under a GSA Blanket Purchase Agreement (GS02F10748) carrying 1,101 task orders with $12 thousand combined potential value, indicating a massive order count at very low per-order value — characteristic of a catalog supplier. Two additional GSA BPAs (GS06F5MCMC with 115 task orders, GS06F5MCAR with 12 task orders) round out the vehicle footprint; the Responsive Strategic Sourcing for Services vehicle carries 4 task orders. This BPA-heavy structure enables federal customers to requisition small-dollar items without individual competitive solicitations.
Activity has remained relatively flat to slightly declining: 13 awards per year in 2022 and 2023, 9 in 2024, 17 in 2025, and 11 through mid-2026. No recompete cliff is evident given the transactional nature of purchase orders, which typically carry completion dates within 30 to 90 days of award. The vendor's award portfolio from 1988 forward suggests long tenure in the federal supply base.
Mcmaster-Carr maintains a minimal subcontract footprint (18 sub awards, or 0.3% of total awards), appearing as a materials supplier under primes including Serco Inc. (command post modernization components), Leidos Inc. (Antarctic Program support goods), Lockheed Martin Corporation (mechanical hardware for defense projects), and others. These sub engagements typically reflect Mcmaster-Carr's role as a catalog provider of components and supplies integrated into larger system-integration or services efforts.
The vendor's primary NAICS profile spans Hand and Edge Tool Manufacturing (811 awards), Industrial Supplies Merchant Wholesalers (286 awards), and Hardware Manufacturing and Distribution, with PSC concentration in Office Supplies (1,292 awards), Hand Tools (745 awards), and Commercial Hardware (497 awards). Mcmaster-Carr competes entirely in full-and-open procurement with no set-aside utilization, positioning itself as a mainstream commercial supplier rather than a specialized contractor.
