Key Features
1. 25–50mm Measuring Range
The 3581-S50 provides a 25–50 mm / 1–2 inch measuring range, making it suitable for measuring the pitch diameter of compatible screw threads and threaded components within this range.
2. High 0.001mm Digital Resolution
With 0.001 mm / 0.00005 inch resolution, the digital micrometer provides detailed readings for precision screw-thread inspection, machining quality control, and dimensional verification.
3. Six Pairs of Measuring Tips Included
The 3581-S50 is supplied with 6 pairs of measuring tips for metric and unified threads with a 60° thread angle. The tip sets cover thread pitches from 0.4–0.5 mm through 5.5–7 mm, providing flexibility for different screw-thread inspection requirements.
4. Non-Rotating Spindle & Ratchet Stop
The non-rotating spindle helps maintain the measuring contact arrangement, while the ratchet stop supports controlled measuring force and repeatable readings. These features are particularly useful for consistent pitch-diameter measurement.
5. Digital Data Output & Automatic Power Off
The 3581 series provides data-output capability through its data interface and includes functions such as on/off, set, mm/inch selection, data transmission, and automatic power-off. This makes the 3581-S50 suitable for measurement workflows where digital data transfer and efficient operation are beneficial.
