In the realm of precision engineering, feeler gauges stand as indispensable tools, enabling meticulous measurements of minute gaps and clearances. These precision instruments are crafted from hardened and tempered steel, boasting exceptional durability and accuracy.
A feeler gauge is a thin, flat blade with a series of precisely calibrated notches. Each notch corresponds to a specific thickness, ranging from a few thousandths of an inch to several millimeters. When inserted into a gap or clearance, the gauge will "feel" for the tightest fit, indicating the exact measurement.
Feeler gauges play a pivotal role in various industries, including:
Feeler gauges come in various types, catering to specific measurement requirements:
Using a feeler gauge is straightforward:
