About the company
Fastening Systems International, doing business as F S I, supplies aerospace fastening systems, blind rivet installation tools, sheet metal repair equipment, laser marking and engraving systems, and composite material repair kits to the federal government as a prime contractor across 113 distinct customer agencies, competing under total small business set-asides on roughly half its delivery orders and in full-and-open competition on the remainder.
F S I is a for-profit small business headquartered in Sonoma, California, with no stated SBA certifications beyond small-business status. The vendor's primary NAICS footprint is Bolt, Nut, Screw, Rivet, and Washer Manufacturing (3,229 recent awards) and Hand and Edge Tool Manufacturing (513 awards), with dominant PSC coding in Hand Tools, Nonedged, Nonpowered (2,947 awards) and Sets, Kits, And Outfits Of Hand Tools (637 awards). Recent concrete capability work includes a $299,901 definitive contract (April 2022) with Defense Logistics Agency Aviation for seven composite repair sets aircraft; a $252,498 delivery order (March 2024) to Air Combat Command for three PT-4500 tool kits under the GSA Multiple Award Schedule (MAS); a $173,239.25 BPA call (June 2024) to the Oklahoma City Air Logistics Complex for reamers, countersinks, and bushings; multiple $38,450–$45,039.60 delivery orders from FAS and Air Education and Training Command for laser etching and marking systems; and recurring fastening-tool kit orders across Air National Guard, Naval Sea Systems Command, and Department of the Army customer bases.
Customer concentration is extreme: the GSA Federal Acquisition Service dominates the footprint at 983 awards (55% of the top-five count) carrying $39.4 million combined potential value, followed distantly by the Department of the Army (491 awards, $2 million), Army Materiel Command TACOM Life Cycle Management Command (425 awards, $981 thousand), Marine Corps (323 awards, $1.3 million), and Navy Pacific Fleet Forces (188 awards, $516 thousand). The two rankings track closely — GSA anchors both volume and dollars — reflecting a business model built heavily on the GSA MAS vehicle. By dollar value, Defense Logistics Agency Aviation ranks second at $3.9 million across 100 awards.
F S I holds a $475,000 GSA Multiple Award Schedule contract (SIN 333TOOL, awarded April 1, 2022, expiring March 31, 2027) and a $4 million Blanket Purchase Agreement with the Oklahoma City Air Logistics Complex (awarded December 8, 2023, expiring November 29, 2028). The Hardware Superstore vehicle carries 3,430 task orders worth $18 million combined potential value; the top five parent vehicles account for the great majority of recorded ordering activity. Approximately half of MAS delivery orders carry total small business set-aside designations, with the remainder full-and-open; BPA calls under the Air Force Materiel Command split similarly, though recent 2026 BPA calls (May–June) all carried total small business set-asides.
Activity has declined year over year — 15 awards in 2022 to 3 through June 2026 — though the portfolio spans 4,356 prime awards since 1985 with combined potential value of $81.9 million and obligated value of $41.7 million (51% of potential). F S I operates as a prime contractor exclusively; three recorded sub-awards since 2023 flow to Lockheed Martin (GMLRS blind rivets for Ukraine) and Defense Systems and Solutions (two FMS logistics support efforts for UH-60 and AGSE).
