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