Mitutoyo 112-237 Point Micrometer 1 Inch Ratchet Stop

Product Description

The MITUTOYO 112-237 is a mechanical point micrometer designed for precise measurement of grooves, steps, narrow slots, and similar hard-to-reach features. It measures from 0 to 1 inch with an accuracy of 0.00015 inches and a resolution of 0.001 inches (0.001 mm). The micrometer features a 30-degree point angle on both the spindle and anvil, a spindle point length of 0.5039 inches, and an 18 mm head diameter. A ratchet stop mechanism ensures consistent measuring force on every use, reducing operator-to-operator variation. The tool is TUV certified and suited for precision inspection work in machining, toolmaking, and mechanical trades.

The MITUTOYO 112-237 is used in applications where a standard flat-anvil micrometer cannot reach the measurement surface. Typical uses include measuring groove widths, step heights, keyways, and recessed features on machined components. The 38 mm throat depth provides clearance for measuring on workpieces with raised shoulders or flanges. The 30-degree point configuration on both anvil and spindle allows access to tight, narrow geometry. This tool is appropriate for quality control, incoming inspection, and precision manufacturing environments.

Compatibility

Designed as an OEM-style precision measurement tool suitable for general machining, toolmaking, and quality inspection applications requiring point-style micrometer geometry.

Installation Notes

Point micrometers are handled and stored by metrology or quality control personnel rather than installed in a mechanical system. Before use, clean the measuring faces and verify the zero setting against a known standard or reference gauge. Protect the point anvils from impact or contact with hard surfaces, as the narrow geometry is susceptible to damage. Store in the provided case to maintain calibration and protect the measuring faces.
