Also named, based in another state

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

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