About Mcmaster-Carr Supply Co

Written by GovTribe AI ·

McMaster-Carr Supply Co, a for-profit industrial distributor based in Elmhurst, Illinois, supplies maintenance, repair, and operations (MRO) materials and general industrial products to federal agencies as a prime contractor under full-and-open competition, with no SBA set-aside designations across its federal footprint. The company maintains a catalog of over 595,000 industrial products including fasteners, hardware, hand tools, electrical components, plumbing supplies, and specialized equipment, competing predominantly on commercial terms rather than small-business reserves.

McMaster-Carr's federal customer base is highly fragmented across 128 distinct agencies, with no single agency dominating the relationship. The top five customers by award count account for only 26% of recent awards: the Department of the Army leads with 490 awards valued at $84 thousand combined potential value, followed by the Department of the Navy United States Pacific Fleet Forces (292 awards, $17 thousand), United States Marine Corps (260 awards, $13 thousand), GSA Federal Acquisition Service (203 awards, $25 thousand), and Army Materiel Command TACOM Life Cycle Management Command (195 awards, $52 thousand). When ranked by dollar value, the concentration shifts noticeably — the top five customers by potential value represent only 27% of combined dollars, led by the Department of Justice Bureau of Prisons Federal Correctional Institution Gilmer ($372 thousand across 158 awards), Department of the Navy Naval Supply Systems Command ($267 thousand across 104 awards), and Department of Justice Bureau of Prisons Federal Correctional Institution Bastrop ($155 thousand across 44 awards). This pattern reflects the vendor's core business: high-volume, low-dollar transactional supply orders to dozens of federal facilities and operational commands rather than large program-level relationships.

Recent representative prime awards include a $13,940.72 firm fixed-price purchase order from Federal Correctional Institution La Tuna for fuses, grommets, sound deadening mat, nuts, rivets, rings, screws, weather seal, fire extinguishers, terminals, electrical tape, and wire (February 2026); a $45,256.28 purchase order from Bureau of Overseas Building Operations for plumbing waterline supplies (June 2025); a $22,348.89 order from Army TACOM Life Cycle Management Command for hinges (August 2023); and a $13,811.42 purchase order from Federal Correctional Institution Bastrop for miscellaneous vehicular parts for upfits (November 2024). These awards exemplify McMaster-Carr's positioning: single purchase orders for discrete component sets, typically under $50 thousand, issued directly by federal installations and commands rather than through prime contractors.

McMaster-Carr holds a seat on two GSA Blanket Purchase Agreements: GS02F10748, which anchors 1,101 task orders valued at $12 thousand combined potential, and GS06F5MCMC, which holds 115 task orders valued at $5 thousand combined potential. These vehicles are the primary channels through which federal buyers access McMaster-Carr's catalog on recurring basis. The vendor's awards distribute heavily across commodity PSC codes: Office Supplies (1,292 awards), Hand Tools, Nonedged, Nonpowered (745 awards), Hardware, Commercial (497 awards), Miscellaneous Items (388 awards), and Signs, Advertising Displays, and Identification Plates (190 awards). Top NAICS categories include Hand and Edge Tool Manufacturing (811 awards), Industrial Supplies Merchant Wholesalers (286 awards), Sign Manufacturing (237 awards), Plastics Bottle Manufacturing (154 awards), and Bolt, Nut, Screw, Rivet, and Washer Manufacturing (77 awards).

Activity has remained consistent over the past five years (13 awards in 2022, 13 in 2023, 9 in 2024, 17 in 2025, and 8 in 2026 as of May), reflecting steady transactional volume rather than growth or decline. The combined potential value across all 5,524 awards in the source is $3.7 million, against $6.8 million in combined obligated dollars — a 187% obligation rate that reflects the high number of zero-dollar or nominal-value orders for standard components where actual spend exceeds initial ceiling estimates.

In its subcontractor role, McMaster-Carr appears in recent sub-awards supporting Serco Inc. on command-post modernization installation for military vehicles (multiple sub-awards in February, April, and May 2026), Leidos on science operations and maintenance support for the United States Antarctic Program (three sub-awards between June 2025 and December 2025), and Lockheed Martin on an NGI AUR development program involving a wide range of fasteners and hardware components (February 2023). The subcontract footprint is minimal relative to prime awards — 18 sub-awards against 5,506 prime awards (less than 1%) — and reflects the vendor's primary positioning as a direct-supply source rather than a systems integrator or program-level prime. McMaster-Carr's federal strategy centers on capturing the baseline MRO demand across federal installations through catalog accessibility and commodity-BPA velocity rather than competing for consolidated program contracts.
