16 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Maryland. They belong to that state's ranking, not this one.

Company	State	Mentions
Fastenal	Washington	7 of 15
Albany County Fasteners	New Jersey	5 of 15
Grainger	Delaware	3 of 15
Hi-Tech Fasteners, Inc.	Michigan	3 of 15
Allied Bolt & Screw	Massachusetts	1 of 15

Named, but placed in another state

The AI answers themselves put these companies in a different state, so they were not counted for Maryland. Whether MacRAE'S lists them elsewhere is not yet known.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial fasteners in Maryland”
2“Who supplies high-strength corrosion-resistant bolts and nuts in Maryland”
3“I need a Maryland fastener supplier for a recurring OEM assembly production run, who should I talk to”
4“Top industrial fastener suppliers in Maryland for manufacturing and MRO buyers”
5“Which Maryland industrial fastener suppliers can provide certified traceable fasteners to ASTM and ISO standards”
6“List 20 industrial fasteners companies in Maryland with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
