Fowler 52-225-176-0 Mechanical Depth Micrometer 6 in

Product Description

The FOWLER 52-225-176-0 is a mechanical depth micrometer designed for precise depth measurement in machining, tooling, and inspection applications. It delivers a 6-inch measurement range using six interchangeable rods, each with a 0.1719-inch (3/16-inch) diameter, and reads to a graduation of 0.001 inches with an accuracy of 0.0002 inches. The ratchet stop thimble provides consistent measuring pressure, reducing operator-to-operator variation. A satin chrome finish minimizes glare under shop lighting. Machinists, tool and die makers, and quality control technicians are the primary installers and users of this instrument.

This depth micrometer is suited for measuring slot depths, counterbore depths, shoulder heights, and step dimensions on workpieces in both job shop and production floor environments. The 2.5-inch base length provides stable seating across a variety of workpiece surfaces. The included fitted case and wrench support organized storage and rod changes in the field or at the bench. It is appropriate for both light industrial and precision inspection use wherever a 6-inch depth range is required.

Compatibility

Designed as a general-purpose mechanical depth micrometer suitable for standard inch-measurement applications requiring up to 6 inches of depth range.

Installation Notes

Depth micrometers should be handled and stored carefully to protect the measuring faces and rod threads from damage. Before use, verify the instrument reads zero with the base seated flat on a reference surface. Select the appropriate rod for the target depth range and ensure it is fully seated and locked before measuring. Calibration should be verified against a known standard at regular intervals per shop quality procedures.
