Mira screw in Valve Guide Pilots

They thread into the valve guide for a stable reference, supporting accurate seat alignment on automotive, motorcycle, and small engine work. Commonly used with seat and guide machine tooling, these pilots fit workshop rebuild and machining tasks where repeatable setup matters.
