Fowler 52-215-004-1 Outside Micrometer Set 0-4 in 4 Pc

Product Description

The FOWLER 52-215-004-1 is a 4-piece mechanical outside micrometer set covering a measurement range of 0 to 4 inches. Each micrometer in the set features a friction ratchet stop thimble for consistent measuring pressure and a solid carbide measuring face for long-term wear resistance. The satin chrome finish reduces glare during use. This set is suited for machinists, tool and die makers, quality control technicians, and precision maintenance professionals who require accurate outside diameter and thickness measurements across multiple ranges.

This micrometer set is designed for use in machine shops, manufacturing facilities, and precision maintenance environments where outside measurements across a 0 to 4 inch range are routinely required. The set covers four incremental ranges, making it a practical bench tool for inspection and dimensional verification work. A carrying case and wrench are included, keeping all components organized and protected between uses.

Key Features

• 4-piece set covering 0 to 4 inches total measurement range
• Friction ratchet stop thimble provides repeatable measuring pressure
• Solid carbide measuring faces resist wear for extended service life
• Non-rotating spindle design prevents part marking during measurement
• Satin chrome finish reduces reflective glare in bright shop environments
• Includes carrying case and wrench for storage and calibration adjustments

Compatibility

Designed as a standard mechanical outside micrometer set suitable for general-purpose precision measurement applications in machining, manufacturing, and quality inspection settings.

Installation Notes

Outside micrometers require no power source and are handled and stored by precision instrument technicians or machinists. Before use, verify zero calibration using the included wrench and reference standards appropriate to each range. Store in the included case to protect measuring faces and thimble mechanisms from contamination and impact damage.
