Mitutoyo 201-158 Snap Gage 7 Inches Dial Display

Product Description

The MITUTOYO 201-158 is a snap gage designed for fixed-limit outside diameter and width measurements at a nominal size of 7 inches. The gage uses a dial indicator display for repeatable readings and features solid carbide anvils that resist wear during high-cycle inspection work. The steel frame provides rigidity and dimensional stability under shop conditions. A dial indicator is not included with this unit, so a separate compatible indicator must be sourced before use. This tool is suited for quality control technicians, machinists, and precision measurement professionals working on production floors or in inspection departments.

The 201-158 is used in dimensional inspection of shafts, pins, and machined workpieces where an outside dimension must be verified at or near 7 inches. It is appropriate for both incoming inspection and in-process gauging in manufacturing environments. The fixed-frame design keeps the measurement point consistent across repeated checks, reducing operator variability. This gage is a practical tool where high-volume part checking demands durability and speed over a caliper or micrometer approach.

Key Features

• Fixed nominal measurement size of 7 inches for consistent outside dimension checking
• Solid carbide anvils for extended wear life in high-cycle inspection use
• Steel frame construction for rigidity and long-term dimensional stability
• Dial indicator display type for easy, repeatable reading
• Indicator not included — compatible dial indicator must be installed separately
• Lightweight at 1 pound for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style fixed snap gage for outside diameter and width inspection of workpieces at a nominal 7-inch measurement range. No specific model compatibility data was provided in the product input.

Installation Notes

Installation of a compatible dial indicator is required before placing this gage into service. Verify that the indicator range and mounting shank are compatible with the gage frame before assembly. Calibrate and zero the gage against a certified master ring or setting standard at the beginning of each inspection session. Handle carbide anvils with care to avoid chipping, and store the gage in its case when not in use to protect the anvil faces and frame geometry.
