gauge block

A gauge block is a precision tool used to measure or set exact lengths in manufacturing and engineering. They are highly accurate, solid blocks made from materials like steel or ceramic, with surfaces carefully finished to ensure precise dimensions. By stacking or comparing these blocks, technicians can calibrate equipment or verify measurements with great accuracy, ensuring parts are produced to exact specifications. Gauge blocks are essential for maintaining quality control in manufacturing processes, where exact measurements are critical for proper fit, function, and performance of assembled components.
