Complete 0–4" coverage in one kit: includes four mechanical micrometers with measuring ranges 0–1", 1–2", 2–3", and 3–4" so you can measure small to medium external dimensions without switching tool types. Reliable repeatable accuracy: mechanical design delivers an accuracy of 01mm, providing consistent results for machining, inspection, and fit checks. Built to last: sturdy casting frame resists distortion under normal workshop use and the carbide measuring faces reduce wear for longer service life. Consistent contact pressure: the integrated ratchet stop ensures the same measuring force each time, reducing user variation and improving repeatability for both experienced technicians and hobbyists. Easy to apply: compact 1" step ranges make it simple to select the correct micrometer for the job; the set covers most external dimension needs up to 4". How this solves common problems Eliminates gaps in measuring range by covering 0–4" in one coordinated set, so you don’t need multiple disparate tools. Reduces measurement error caused by inconsistent pressure through the ratchet stop. Minimizes wear-related inaccuracy with carbide heads and a rigid casting frame, lowering the need for frequent replacement or recalibration. Key attributes at a glance Function: mechanical micrometers for external measurements Set composition: four micrometers — 0–1", 1–2", 2–3", 3–4" Accuracy: 01mm Construction: sturdy casting frame with carbide measuring faces Feature: ratchet stop mechanism for consistent pressure Intended users: machinists, inspection personnel, mechanics, and hobbyists Practical applications Precision machining: check shaft diameters and turned parts during production to maintain tolerance control. Automotive maintenance: measure brake or axle components and other external parts for wear and replacement decisions. Workshop fabrication and hobby projects: verify dimensions on assembled parts, fittings, and small welded components to ensure proper fit. What you get A coordinated set of four reliable mechanical micrometers covering 0–4" in 1" increments, designed for durable, repeatable external measurements in professional and home workshop environments.
