External Dimension Verification

Snap & Width Gauges

Precision inspection gauges used to check external dimensions such as shaft diameter, thickness, and width of components using the GO / NO-GO principle — enabling fast and reliable production-floor inspection.

Overview

About Snap & Width Gauges

Snap & Width Gauges are precision inspection gauges used to check external dimensions such as shaft diameter, thickness, and width of components. These gauges operate on the GO / NO-GO principle, allowing quick and reliable verification of whether a part falls within specified tolerance limits.

Snap and Width Gauges are widely used in automotive, aerospace, machine tool, and precision engineering industries for fast inspection in production environments. At Size Gauge, we manufacture high-precision Snap Gauges and Width Gauges using high-quality hardened tool steel to ensure accuracy, durability, and long service life.
