Groz 4-5 Inch Outside Micrometer, Hardened Spindle, Satin Chrome Finish, MM/4-5

The Groz MM/4-5 4-5 Inch Outside Micrometer is a high-quality precision measuring tool crafted for external dimensional checks in demanding industrial and laboratory environments. This micrometer provides reliable and ultra-precise measurements within a range of 4 to 5 inches, ensuring accuracy to within ±0.0001 inch. It is ideal for machinists, quality inspectors, and manufacturing professionals who require repeatable and error-free readings on workpieces or fixtures.

The instrument is built around a hardened, wear-resistant spindle featuring finely cut threads to minimize backlash and ensure a smooth, steady movement during measurement. A satin chrome finish on both the thimble and barrel reduces glare and resists corrosion, while the clear, deep black graduations are permanently etched for maximum readability, even in challenging lighting conditions. Users benefit from a ratchet stop mechanism, which guarantees consistent pressure and highly repeatable readings, boosting confidence in every result.

For ongoing accuracy, the micrometer offers convenient zero adjustment using a spanner wrench, enabling users to recalibrate as required over time. Supplied with a master for size verification (except for the 0 - 25 mm/0 - 1 inch version), the tool is suitable for a wide range of industrial, machining, and laboratory applications, including quality control, toolmaking, and equipment maintenance. The robust build quality ensures longevity and reliable performance in high-throughput environments.

The Groz MM/4-5 Outside Micrometer stands out for its combination of durable construction, user-friendly operation, and exceptional measurement precision. Its ergonomic design ensures comfortable handling during extended use, and it can be quickly adapted to varied workplace needs through its full set of key adjustment features.
