Fowler 52-253-102-1 Outside Micrometer 2 Inch Range

Product Description

The FOWLER 52-253-102-1 is a mechanical outside micrometer designed for precise linear measurement in machining, fabrication, and inspection work. It covers a 2-inch measurement range with a graduation of 0.001 inches and an accuracy of 0.0001 inches, making it suitable for close-tolerance work in tool rooms, job shops, and field service environments. The thimble uses a ratchet stop mechanism to deliver consistent measuring force, reducing operator-to-operator variation. Measuring faces are solid carbide for durability against wear. A positive lever locking clamp holds the spindle position for reliable reading transfer.

This micrometer is used wherever precise outside diameter or thickness measurements are required on shafts, fasteners, tubing, stock material, or machined parts. It is a standard hand tool for machinists, quality control technicians, millwrights, and maintenance professionals working in industrial, commercial, and trade settings. The included case, standards, and wrench make it a complete out-of-the-box measuring setup for bench or field use.

Installation Notes

This instrument requires no installation but should be handled and stored according to standard metrology practices. Before use, verify calibration against the included standards and clean measuring faces with a lint-free cloth. Store in the provided case when not in use to protect carbide faces and maintain calibration. Avoid dropping or applying side-loading force to the spindle.
