Northwestern Fixture Keys: Precision Locating Components

Premium-Grade Fixture Keys from Your Trusted Michigan-Based Distributor

NW fixture keys—also called tooling keys—are used to locate and align fixtures on machine tables, subplates, and tooling plates for repeatable setup (application dependent). They help a fixture return to the same position after removal, reducing setup time and improving consistency for machining and inspection operations. Fixture keys are commonly used with fixture plates, vises, and modular workholding systems where accurate positioning relative to T‑slots or reference edges matters.
