Mitutoyo 201-156 Snap Gage Solid Carbide Anvil Dial

Product Description

The MITUTOYO 201-156 is a snap gage designed for fast, repeatable outside-dimension inspection on the shop floor or in the metrology room. The frame is constructed of steel for rigidity and durability under regular production use. Anvils are solid carbide, which resists wear and maintains dimensional accuracy over long service intervals. The gage uses a dial display indicator, giving technicians a direct-reading analog output without requiring a separate amplifier or digital readout unit. Note that an indicator is not included with this unit and must be sourced separately.

Snap gages of this type are used in manufacturing, machining, and quality-control environments to verify shaft diameters, turned parts, and other external features against a fixed tolerance. They are commonly deployed at inspection stations, inline at CNC machines, or in tool-and-die shops. The 201-156 is suited for professional metrology technicians, quality inspectors, and precision machinists who require consistent go/no-go or comparative measurement capability.

Key Features

• Solid carbide anvils resist wear for extended service life in high-cycle inspection use
• Steel frame provides rigidity and stability during measurement
• Dial display indicator type allows direct analog readout
• Indicator not included, allowing pairing with a preferred dial indicator
• Compact snap-gage design supports fast, single-handed external dimension checks

Compatibility

Designed as an OEM-style snap gage for use with compatible dial indicators in standard metrology and quality-inspection applications requiring external dimensional measurement.

Installation Notes

Installation and setup should be performed by a qualified metrology technician or precision machinist familiar with snap gage zeroing and calibration procedures. Before mounting an indicator, ensure the gage frame and anvil surfaces are clean and free of chips or debris. Set the gage to a known master or reference standard before taking measurements to establish the correct zero reference. Follow the indicator manufacturer's mounting torque and contact-point specifications when attaching the dial indicator.
