Why Steinjäger

50+ years of real manufacturing

Steinjäger grew out of Midwest Control Products Corp. — a custom manufacturer building motion-control and linkage hardware for industry since 1967. We point that same in-house capability — forging, machining, welding, powder coating — at the people who actually wrench.

That means parts that fit, hardware that holds up, and the same in-house tooling we run for industry — built to take a beating off the pavement.
