Fowler 52-240-005-1 Outside Micrometer 5 in Range

Product Description

The FOWLER 52-240-005-1 is a mechanical outside micrometer built for precise external measurement in shop, field, and inspection environments. It covers a measurement range up to 5 inches with a graduation of 0.0001 inches and an accuracy of 0.0025 inches, making it suitable for applications where consistent, repeatable readings are required. The ratchet stop thimble controls applied force at the measuring faces, reducing operator-to-operator variation. Solid carbide measuring faces resist wear during repeated use. This micrometer ships with a case and a wrench and is used by machinists, quality technicians, and precision tradespeople.

The 52-240-005-1 is suited for external diameter and thickness measurements across a wide range of workpieces up to 5 inches. The quick, easy zero adjustment on the sleeve allows the user to zero the instrument without removing it from service for extended recalibration. It is a non-digital, non-counter instrument - readings are taken directly from the thimble and sleeve graduations. Typical applications include dimensional inspection of mechanical components, shaft measurement, and material stock verification in manufacturing, maintenance, and quality-control settings.

Key Features

• Accuracy of 0.0025 inches for reliable dimensional verification
• Ratchet stop thimble provides consistent, controlled measuring force
• Solid carbide measuring faces for extended wear resistance
• Quick zero adjustment on sleeve for fast field calibration
• Includes protective case and wrench

Compatibility

Designed as a general-purpose mechanical outside micrometer for external measurement of workpieces up to 5 inches in diameter or thickness across standard machining and inspection applications.

Installation Notes

This instrument is used by machinists, quality technicians, and precision tradespeople. Clean the measuring faces with a lint-free cloth before use and verify zero at the reference standard. Store in the included case to protect the carbide faces and maintain calibration. Do not use the instrument to measure rotating workpieces or surfaces with burrs that could damage the measuring faces.
