It features a 0.5-inch measurement range, a 0.51-inch thimble diameter, and a 0.2-inch spindle diameter with a flat spindle end. Accuracy is rated to 0.0002 inches, making it suitable for high-tolerance work in machining, metrology, and precision assembly environments. The satin chrome finish resists corrosion and reduces glare during use. At 2.64 inches in overall length and 3 pounds, this head is compact enough for integration into custom fixtures or measuring setups. A clamp nut is supplied for secure mounting. Machinists, toolmakers, and metrologists are the primary installers and users of this component.\u003c\/p\u003e\n\u003cp\u003eThis micrometer head is intended for use in precision measurement applications where a mechanical, non-digital readout is required. It is suited for integration into jigs, fixtures, optical stages, and custom measuring instruments across manufacturing, quality control, and laboratory environments. The rotating spindle design allows for smooth travel adjustment, and the absence of a digital counter keeps the mechanism straightforward and easy to service. Residential HVAC, plumbing, or electrical trade applications are not typical uses for this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5-inch measurement range with accuracy to 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eFlat spindle end for consistent contact on flat workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eRotating spindle for smooth, repeatable linear travel adjustment\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish for corrosion resistance and reduced glare\u003c\/li\u003e\n  \u003cli\u003eClamp nut included for secure fixture or stage mounting\u003c\/li\u003e\n  \u003cli\u003eMechanical operation with no digital counter — simple, reliable, serviceable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard mechanical micrometer head for integration into precision fixtures, optical stages, jigs, and custom measuring instruments requiring a 0.5-inch range and flat spindle configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or metrologists integrating the head into a fixture or measuring stage. Secure the head using the supplied clamp nut and verify that the spindle axis is properly aligned with the measurement axis before use. Do not overtighten the clamp nut, as this can affect spindle travel and measurement accuracy. Verify calibration against a known reference standard after installation.\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 Diameter\u003c\/strong\u003e: 0.2 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: 2.64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\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\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: MS150825010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698779095346,"sku":"MS150825010","price":95.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b5f5bd5f9b51dc769be3e6bcf3de92a.jpg?v=1788367769","url":"https:\/\/voomisupply.com\/products\/spi-ms150825010-mechanical-micrometer-head-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
