At 17 inches in length and with accuracy up to 0.0002 inches, it provides a reliable reference for confirming micrometer spindle alignment and measurement consistency. The included heat insulating handle allows the technician to hold the standard without transferring body heat to the bar, which would otherwise cause thermal expansion and introduce measurement error. This standard is intended for use by metrology technicians, quality control personnel, and precision machinists who require traceable calibration references.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is suited for use in machine shops, toolrooms, inspection departments, and manufacturing environments where outside micrometers must be periodically verified or zeroed. Its spherical end geometry provides consistent, repeatable contact points when checking micrometer anvil and spindle alignment. The 17-inch length makes it appropriate for larger-range micrometers used in production and inspection of shaft diameters, bore components, and similar workpieces. The calibrated construction confirms the standard has been measured and verified against traceable references prior to shipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpherical end geometry ensures repeatable, consistent contact during calibration checks\u003c\/li\u003e\n  \u003cli\u003eAccuracy up to 0.0002 inches for high-precision micrometer verification\u003c\/li\u003e\n  \u003cli\u003e17-inch overall length accommodates larger-range outside micrometers\u003c\/li\u003e\n  \u003cli\u003eIncludes heat insulating handle to minimize thermal expansion error during use\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated prior to shipment for out-of-box readiness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with outside micrometers requiring a calibration reference standard.

Store the standard in its case when not in use and allow it to acclimate to the ambient temperature of the inspection area before use. Verification of calibration standards should be performed by a qualified metrology technician in accordance with applicable quality system requirements such as ISO 9001 or AS9100 procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Length\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Spherical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Insulating Handle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Micrometers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.25 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: MS160712017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51712546341170,"sku":"MS160712017","price":101.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fedfa37ed2a28a15b7a472dd7482e5b.jpg?v=1788486584","url":"https:\/\/voomisupply.com\/products\/spi-ms160712017-micrometer-calibration-standard-17-in","provider":"Voomi Supply","version":"1.0","type":"link"}
