A Snap Gauge is a precision measurement tool used to inspect the external dimensions of shafts, rods, and other cylindrical components. It features a “C”-shaped frame with fixed and adjustable anvils or jaws, designed to measure a specific size range. Snap gauges are typically used for quick, repetitive checking of part dimensions, with the “Go” and “No-Go” concept. If the component fits through the “Go” side but is blocked by the “No-Go” side, it confirms that the part is within acceptable tolerance limits.
These gauges are often used in manufacturing environments where high-volume production requires fast and reliable inspection. They are made from hardened materials to ensure durability and accuracy over time. Snap gauges eliminate the need for manual measurements, reducing the risk of human error, and provide consistent quality control for parts like shafts, spindles, and fasteners. They are widely used in industries such as automotive, aerospace, and mechanical engineering for dimensional verification.
