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 Massachusetts”
2“Who supplies custom quick-change machining fixtures in Massachusetts”
3“I need a Massachusetts 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 Massachusetts for manufacturing engineering buyers”
5“Which Massachusetts 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 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.
