Mitutoyo 201-151 Snap Gage Dial Solid Carbide Anvil

Product Description

The MITUTOYO 201-151 is a snap gage designed for fast, repeatable outside-diameter and thickness measurements in precision machining and quality-control environments. The frame is constructed from steel for rigid, stable support during repeated use. Measurement is read through a dial indicator display, giving technicians a clear, direct readout at the point of contact. The gage ships without an indicator included, so the user pairs it with a compatible dial indicator to complete the assembly. Machinists, quality inspectors, and tool room technicians are the primary users of this type of instrument.

The 201-151 is suited for production-floor and inspection-room applications where outside dimensions must be checked quickly against a set tolerance. It is used in both light manufacturing and precision machining shops. The solid carbide anvil contacts are resistant to wear, making this gage well-suited for high-cycle inspection routines where consistent anvil geometry is critical to measurement accuracy. No specific OEM model compatibility data was provided in the product information.

Key Features

• Solid carbide anvils resist wear during high-cycle inspection use
• Steel frame provides rigid, stable structure for repeatable measurements
• Dial display format gives direct visual readout at the measurement point
• Indicator not included — compatible with separately sourced dial indicators
• Compact snap-gage form factor speeds up outside-dimension checks on production runs

Compatibility

Designed as an OEM-style precision measuring instrument for general outside-diameter and thickness inspection applications in machining and quality-control settings.

Installation Notes

Snap gages are installed and set by machinists or metrology technicians. Before setting the gage, zero it against a certified master ring or reference standard of known dimension following the manufacturer calibration procedure. Protect anvil surfaces from impact and contamination, as carbide contacts can chip if dropped. Store the gage in its case when not in use to maintain calibration and protect the frame.
