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 California”
- 2“Who supplies high-volume brass precision turned inserts in California”
- 3“I need a California 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 California for OEM buyers”
- 5“Which California screw machine shops can handle multi-spindle turning of complex geometries”
- 6“List 20 screw machine products and turned parts companies in California 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.
