Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not California. They belong to that state's ranking, not this one.

Company	State	Mentions
Spring Industries	Illinois	5 of 15
Engineered Spring Products – MW Components	Texas	1 of 15
MW Components – Engineered Spring Products	Texas	1 of 15

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 industrial springs in California”
2“Who supplies custom high-cycle compression springs in California”
3“I need a California spring manufacturer for a 100,000-piece industrial valve spring run, who should I talk to”
4“Top industrial spring suppliers in California for OEM engineering buyers”
5“Which California spring manufacturers can produce aerospace-grade springs to MIL-spec requirements”
6“List 20 industrial springs 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.
