Fowler 52-246-001-1 Blade Micrometer 1 Inch Mechanical

Product Description

The FOWLER 52-246-001-1 is a mechanical blade micrometer designed for precision measurement in tight grooves, keyways, and narrow slots where standard anvil micrometers cannot reach. It measures up to 1 inch with an accuracy of 0.0001 inches and a graduation of 0.0001 inches, delivering the resolution required for close-tolerance inspection work. The blade thickness of 0.03 inches and a blade depth of 0.315 inches allow the tool to reach into confined features without interference. A ratchet thimble ensures consistent measuring force, and the non-rotating spindle prevents blade movement during contact. The satin chrome finish reduces glare under shop lighting. Machinists, toolmakers, and quality control technicians are the primary users of this instrument.

This blade micrometer is suited for dimensional inspection in machine shops, manufacturing facilities, and tool rooms. It is used when measuring slot widths, groove depths, and recessed features that require a thin blade profile to seat properly against the workpiece. The 0.0001-inch graduation makes it appropriate for applications demanding tight dimensional control. The included case and wrench support proper storage and adjustment, making it practical for bench use as well as field inspection work.

Compatibility

Designed as a standard 0 to 1 inch range mechanical blade micrometer suitable for general precision measurement applications in machining and inspection environments.

Installation Notes

This instrument requires no installation. Prior to use, clean the blade anvils and spindle face with a lint-free cloth and verify the zero setting with the included wrench. Store the micrometer in its case when not in use to protect the blade from damage. Calibration should be performed at regular intervals per the shop quality plan or applicable metrology standards.
