Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Connecticut. 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 jigs, fixtures and custom tooling in Connecticut”
2“Who supplies custom quick-change machining fixtures in Connecticut”
3“I need a Connecticut partner to design and build production jigs and fixtures for a new assembly line, who should I talk to”
4“Top jigs, fixtures and custom tooling suppliers in Connecticut for manufacturing engineering buyers”
5“Which Connecticut jig, fixture and custom tooling specialists can design and build fully modular CNC workholding systems”
6“List 20 jigs, fixtures and custom tooling companies in Connecticut 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.
