Precision machined parts at Peak Precision

We're not afraid of difficult parts — there has never been a job that we haven't conquered.

— Bill Balcerzak, Founder · B&B Products, Inc.

That spirit carries forward. In 2026, new ownership was established and launched the beginning of Peak Precision, Inc. — the next chapter of a machining legacy that started in a two-car garage in 1969. Same process discipline. Same customer-first values. Family owned and operated, with new energy and a sharper edge.

Quality Process

Quality Control & Inspection

Quality at Peak isn't a final checkpoint. It's how we quote, fixture, machine, and inspect — so the first piece and the last piece are the same conversation.

1000
1000:1 Visual Inspection System
High-magnification camera inspection examines deep inside bores and critical features. Inspection photos available for customer documentation upon request.
