Mitutoyo 201-251 Snap Gage with Dial Indicator

Product Description

The MITUTOYO 201-251 is a snap gage equipped with a dial indicator display, designed for fast and repeatable outside-dimension measurements on machined or manufactured parts. Snap gages are fixed-limit or adjustable gauging tools used to verify that a workpiece dimension falls within a specified tolerance range. The dial indicator provides direct visual readout during the gauging operation. At 1.95 pounds, this is a bench-ready or line-side inspection instrument suited for machinists, quality control technicians, and toolroom professionals.

Snap gages of this type are commonly used in production and inspection environments where outside diameters, shaft dimensions, or flat part thicknesses must be checked against tolerance. The dial indicator display on the MITUTOYO 201-251 allows the operator to read deviation from a set master dimension quickly and clearly. This unit is appropriate for use in machine shops, manufacturing facilities, and metrology labs where consistent dimensional verification is required.

Key Features

• Dial indicator display included for direct deviation readout
• Snap gage form factor enables fast, repetitive dimensional checks
• Suitable for outside diameter and flat dimension inspection
• Compact and portable at 1.95 pounds for bench or line-side use
• Packaged as a single-unit quantity

Compatibility

Designed as an OEM-style replacement or direct-use snap gage for standard dimensional inspection applications in production and quality control settings.

Installation Notes

Snap gages are installed and set by quality control technicians or machinists using a calibrated master setting ring or reference standard before use. Ensure the gage is zeroed against the master dimension prior to measuring production parts. Handle the instrument carefully to avoid dropping or impacting the dial indicator, as shock can affect calibration accuracy. Follow your facility metrology procedures and applicable inspection standards when setting and using this instrument.
