It features a 13mm plain thimble diameter (0.5118 inches), a 5mm spherical spindle with a 17.5mm spindle length, and an overall body length of 2.64 inches. The measuring face is made from SKS3 tool steel, a hardened material well suited for repeated contact in dimensional gauging work. Graduation is 0.01mm, and accuracy is rated to 0.002mm. A clamp nut is included. The spindle rotates and accepts both flat and spherical end configurations, giving the installer flexibility across a range of fixture and jig setups.\u003c\/p\u003e\n\u003cp\u003eThis micrometer head is used in precision instrument assemblies, machine tool fixtures, optical bench setups, and custom gauging stations where repeatable fine adjustment is required. It is well suited for integration into OEM equipment, inspection fixtures, and R and D lab rigs. The plain stem design allows straightforward mounting in a standard bored housing. The chrome finish provides corrosion resistance in workshop environments. Machinists, metrologists, and precision instrument technicians are the primary users of this type of component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13mm plain thimble diameter (0.5118 inches) with chrome finish\u003c\/li\u003e\n  \u003cli\u003eRotating spherical spindle, 5mm diameter, 17.5mm long\u003c\/li\u003e\n  \u003cli\u003eSKS3 hardened steel measuring face for durability under repeated contact\u003c\/li\u003e\n  \u003cli\u003e0.01mm graduation with 0.002mm accuracy rating\u003c\/li\u003e\n  \u003cli\u003e9.5mm diameter plain stem, 9.5mm long, for standard bore mounting\u003c\/li\u003e\n  \u003cli\u003eClamp nut included; no digital counter or reverse reading\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 precision gauging fixtures, machine tool positioning assemblies, and instrumentation rigs that accept a 9.5mm plain stem micrometer head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or precision instrument technician. Secure the plain stem in a properly bored housing and tighten the clamp nut to hold position without distorting the stem. Ensure the mounting bore is clean and free of burrs before insertion to protect the measuring face and spindle. Do not apply lateral force to the spindle during installation, as this can affect calibration and surface finish integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.002mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.01mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Diameter\u003c\/strong\u003e: 13mm (0.5118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Shape\u003c\/strong\u003e: Spherical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Length\u003c\/strong\u003e: 17.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 9.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 9.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: SKS3 hardened steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome\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\u003eSeries\u003c\/strong\u003e: 148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Paper case\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 148-804-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559028326706,"sku":"148-804-10","price":97.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80a7fc45f8ae216093ed3c3825a0ec8b.jpg?v=1786426158","url":"https:\/\/voomisupply.com\/products\/mitutoyo-148-804-10-mechanical-micrometer-head","provider":"Voomi Supply","version":"1.0","type":"link"}
