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