Fowler 52-244-201-1 Ball Anvil Micrometer 0-1 Inch

Product Description

The FOWLER 52-244-201-1 is a mechanical outside micrometer with a ball anvil design, built for precision measurement in the 0 to 1 inch range. It features a digital counter readout alongside a satin chrome graduated thimble, reducing reading errors in fast-paced shop environments. The carbide-faced anvil and spindle resist wear on hardened workpieces and provide long-term measurement consistency. A ratchet stop thimble ensures repeatable, consistent contact pressure on every measurement. The baked enamel frame adds corrosion resistance and durability. This tool is intended for use by machinists, metrology technicians, and precision inspection personnel who require reliable, traceable measurement to 0.0001 inch graduation.

The 52-244-201-1 is suited for dimensional inspection tasks in machine shops, quality control labs, and manufacturing environments where curved or convex surfaces require a ball anvil contact point. The ball anvil face allows accurate measurement on round stock, wire, tubing walls, and similar workpieces where a flat anvil would not seat properly. It meets Federal Accuracy Specifications, making it appropriate for inspection work requiring documented accuracy standards. A positive lock nut allows the spindle position to be secured during layout or transfer measurements.

Key Features

• Carbide anvil and spindle faces for wear resistance on hardened materials
• Digital counter readout reduces parallax and misreading errors
• 0.0001 inch graduation for fine-resolution measurement
• Ratchet stop thimble provides consistent measuring pressure
• Positive lock nut secures spindle position during transfer measurements
• Baked enamel frame with satin chrome graduations for durability and legibility
• Meets Federal Accuracy Specifications

Compatibility

Designed as a direct-use mechanical micrometer for general dimensional inspection applications requiring a ball anvil contact in the 0 to 1 inch measurement range.

Installation Notes

Calibrate or verify the micrometer against a known standard before placing it into service. Store in the supplied case when not in use to protect the carbide faces and graduated surfaces. Clean contact surfaces with a lint-free cloth before measuring to prevent debris from affecting readings. This instrument should be handled and maintained by personnel familiar with precision measuring tool practices.
