HARDEN Professional 25–50mm Outside Micrometer | 580835

Description

Achieve master-level precision with the HARDEN 580835 Outside Micrometer. Designed for machinists, automotive engineers, and quality control technicians, this instrument is the definitive solution for measuring the external dimensions of shafts, rotors, and industrial components. When a caliper isn't accurate enough, the 580835 provides the critical data needed for high-performance mechanical assembly.

Forged with a heavy-duty enameled frame, this micrometer features carbide-tipped measuring faces that resist wear and maintain flatness over years of industrial use. The precision-milled thimble delivers a 0.01mm graduation, while the integrated ratchet stop ensures consistent pressure for every measurement—eliminating user-induced errors. Housed in a high-impact protective plastic case, the HARDEN 580835 comes with a standard calibration gauge to ensure your tool remains accurate out of the box.

Key Features & Benefits:

• 25–50mm Precision Range: The essential size for measuring crankshaft journals, pistons, and industrial tooling.

• 0.01mm Ultra-Fine Graduation: Provides the high-resolution data required for meeting strict engineering tolerances.

• Carbide-Tipped Measuring Faces: Flat, hard-wearing surfaces ensure a lifetime of accurate "zeroing" and measurement.

• Integrated Ratchet Stop: Guarantees uniform pressure for repeatable, accurate readings regardless of the operator's "feel."

• Hardened Stainless Steel Spindle: Precision-milled threads for smooth operation and superior rust resistance.

• Heat-Insulated Frame: The enameled grip minimizes heat expansion caused by hand warmth, preserving the tool's accuracy during long sessions.

• Protective Storage: Includes a durable plastic box and a calibration standard (50mm) for field verification.
