It features a 0.5-inch measurement range with a flat-face rotating spindle and delivers accuracy to 0.0002 inch, making it suitable for applications that demand fine, repeatable adjustment. The thimble diameter measures 0.51 inches and the overall body length is 2.3 inches. A clamp nut is included, and the unit ships with a short-form certificate of calibration. The satin chrome finish resists corrosion and reduces glare during inspection use. Calibration is confirmed at the factory before shipment.\u003c\/p\u003e\n\u003cp\u003eThis micrometer head is used in both light industrial and laboratory settings where a compact, non-digital measurement head is preferred over electronic alternatives. Typical applications include integration into machine slides, depth-gauging fixtures, test rigs, electronics assembly tooling, and optical instrument staging. The flat spindle face is suited for contact against flat workpiece surfaces without additional adapter tips. The non-rotating spindle body design keeps contact geometry consistent throughout the measurement stroke.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccuracy to 0.0002 inch for precise positioning and measurement control\u003c\/li\u003e\n  \u003cli\u003eFlat-face spindle suited for flat-surface contact applications\u003c\/li\u003e\n  \u003cli\u003e0.51-inch thimble diameter for secure grip and easy adjustment\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish for corrosion resistance and low-glare surface\u003c\/li\u003e\n  \u003cli\u003eIncludes short-form certificate of calibration\u003c\/li\u003e\n  \u003cli\u003eClamp nut included for secure mounting in fixtures\u003c\/li\u003e\n  \u003cli\u003eNo digital counter — fully mechanical operation with no battery dependency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade component for mechanical micrometer head applications in machine tools, gauging equipment, test fixtures, and optical and electronic instruments where a 0.5-inch range flat-spindle head is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a metrology technician, machinist, or instrumentation technician. Ensure the mounting bore and clamp nut thread are compatible with your fixture before installation. Secure the head using the supplied clamp nut and verify zero calibration after mounting, as fixture clamping torque can shift the reference point. Do not exceed the rated measurement range of 0.5 inches, as overtravel can damage the spindle thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Diameter\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Shape\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Nut Supplied\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Short Form Certificate of Calibration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS150825002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720467480882,"sku":"MS150825002","price":93.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4316f8c463a5be5a57228f08235cb31f.jpg?v=1788564471","url":"https:\/\/voomisupply.com\/products\/spi-ms150825002-mechanical-micrometer-head-flat-spindle","provider":"Voomi Supply","version":"1.0","type":"link"}
