Fowler 52-240-010-1 Mechanical Outside Micrometer 10 in

Product Description

The FOWLER 52-240-010-1 is a mechanical outside micrometer built for precise external dimensional measurement across a 10-inch range. Graduation reads to 0.0001 inches with an accuracy of 0.0003 inches, making it suitable for close-tolerance inspection work in fabrication, machining, and mechanical service environments. The ratchet stop thimble ensures consistent measuring force on each reading, reducing operator-to-operator variation. Solid carbide measuring faces resist wear during repeated use. A quick-adjust zero feature on the sleeve simplifies calibration at the start of each job. This tool ships with a protective case and a wrench for sleeve adjustment.

The 52-240-010-1 is used in shops, inspection departments, and field service settings where external measurements up to 10 inches must be verified to tight tolerances. Machinists, tool-and-die technicians, quality control inspectors, and precision fabricators are the primary users. It is well-suited for measuring large-diameter stock, shafts, housings, and fabricated components where a standard 1-inch micrometer set would not reach.

Key Features

• 10-inch measurement range for large-diameter workpieces
• 0.0001-inch graduation for fine resolution readings
• 0.0003-inch accuracy across the full range
• Ratchet stop thimble delivers consistent measuring force
• Solid carbide measuring faces for long-term wear resistance
• Quick zero adjustment on sleeve reduces setup time
• Includes protective case and sleeve wrench

Compatibility

Designed as a standalone mechanical outside micrometer for general precision measurement applications requiring a 10-inch range.

Installation Notes

No installation is required for this hand tool. Before use, verify zero calibration using the included wrench and sleeve adjustment feature. Keep measuring faces clean and free of debris to maintain accuracy. Store in the included case when not in use to protect the measuring faces and thimble mechanism.
