Insize Range Screw Thread Micrometer with Non Rotating Spindle (25 to 100 mm)

The Insize Range Screw Thread Micrometer with Non-Rotating Spindle is a specialized measuring tool designed for accurately measuring the pitch diameter of screw threads. This type of micrometer is commonly used in industries such as manufacturing, machining, engineering, and automotive, where precise measurements of screw threads are crucial for ensuring proper fit, functionality, and quality of threaded components.Here are the key features and components of the Insize Range Screw Thread Micrometer with Non-Rotating Spindle:1. **Pitch Diameter Measurement**: The micrometer is specifically designed to measure the pitch diameter of screw threads. The pitch diameter is a critical dimension that determines the effective size of the thread and is essential for verifying thread geometry and thread fit.2. **Non-Rotating Spindle**: One of the distinctive features of this micrometer is its non-rotating spindle. The spindle remains stationary during measurements, preventing potential errors or inaccuracies that can occur due to spindle rotation. This design ensures that the micrometer maintains consistent contact with the threaded surface, leading to more accurate and repeatable measurements.3. **Anvil and Spindle Design**: The micrometer typically includes specialized anvils and a non-rotating spindle designed specifically for screw thread measurement. The anvils and spindle have precision-ground measuring faces that ensure reliable contact with the thread flanks, minimizing errors and ensuring accurate pitch diameter readings.4. **Digital Readout**: Many modern versions of the micrometer come with a digital readout or display that provides clear and easy-to-read measurement readings. The digital display eliminates reading errors associated with traditional analog micrometers and allows for precise measurement readings in metric (millimeters) or imperial (inches) units.5. **Measuring Range**: The micrometer is available in various models with different measuring ranges to accommodate a wide range of screw thread sizes and pitches. Common measuring ranges may include metric threads, inch threads, and specialized thread forms such as Acme threads or Whitworth threads.6. **Locking Mechanism**: To ensure measurement stability and accuracy, the micrometer may feature a locking mechanism that allows users to secure the position of the spindle once the desired measurement is obtained. This prevents accidental movement during measurements and ensures consistent results.7. **Calibration and Calibration Standards**: The micrometer may come with calibration standards or certificates to ensure its accuracy and traceability to recognized calibration standards. Regular calibration and verification are essential to maintaining measurement accuracy over time.Overall, the Insize Range Screw Thread Micrometer with Non-Rotating Spindle is a precision measurement tool that provides accurate and reliable measurements of screw thread pitch diameters. Its non-rotating spindle design, digital readout, measuring range options, locking mechanism, and calibration standards make it a valuable instrument for industries and professionals involved in screw thread manufacturing, inspection, and quality control.
