The MITUTOYO Thickness Feeler Gauge 0.03–0.5mm is a precision measuring tool designed for accurate gap and thickness measurement in mechanical, automotive, and industrial applications.

This feeler gauge set typically includes 13 precision-ground leaves, covering a range from 0.03mm to 0.5mm, allowing fine measurement of clearances and tolerances. The leaves are manufactured from hardened steel for durability and long-term accuracy.

Each blade is clearly stamped with its thickness value, enabling quick identification during use. The leaves can be used individually or combined to achieve exact measurement thickness, making the tool highly versatile.

Depending on the model (e.g., 184-302S), it features 150mm long straight leaves, allowing easy access to deep or narrow spaces.
