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 screw machine products and turned parts in Illinois”
2“Who supplies high-volume brass precision turned inserts in Illinois”
3“I need a Illinois screw machine partner for a 100,000 piece run of stainless steel fittings, who should I talk to”
4“Top screw machine products and turned parts suppliers in Illinois for OEM buyers”
5“Which Illinois screw machine shops can handle multi-spindle turning of complex geometries”
6“List 20 screw machine products and turned parts companies in Illinois 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.
