It features a plain thimble and a satin chrome finish for durability and readability under shop conditions. Graduation is 0.01mm, and accuracy is rated at 0.004mm (0.0002 inches). Operation is fully mechanical with no digital counter, making it reliable in environments where battery-powered instruments are impractical. The included anvil is purpose-built for screw thread contact geometry. This instrument is used by machinists, tool room technicians, and quality control inspectors who require repeatable, traceable measurements of threaded fasteners and workpieces.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 56323 is suited for use in machine shops, tool rooms, and manufacturing environments where screw thread diameter verification is part of the inspection process. It is appropriate for both production and maintenance settings. The 0 to 25mm range covers a wide variety of common metric fastener and part thread profiles encountered in precision machining and assembly work. No rotating spindle is present, which simplifies handling during single-handed measurement tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMechanical operation — no batteries or digital components required\u003c\/li\u003e\n  \u003cli\u003e0.01mm graduation for fine, readable incremental measurement\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.004mm (0.0002 inches) for precision thread inspection\u003c\/li\u003e\n  \u003cli\u003ePlain thimble design for straightforward, consistent grip\u003c\/li\u003e\n  \u003cli\u003eIncludes anvil suited for screw thread contact geometry\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces glare and resists corrosion in shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style mechanical screw thread micrometer for use in metric measurement applications requiring a 0 to 25mm measurement range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is handled and used by machinists and quality control technicians rather than installed in a system. Prior to use, verify the micrometer reads zero correctly at the closed position using the supplied anvil and adjust as needed per standard calibration procedure. Store in a protective case away from extreme temperatures and humidity to maintain calibration integrity. Do not overtighten the thimble during measurement, as this can introduce measurement error or damage the instrument.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 25mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.01mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.004mm (0.0002 inches)\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\u003eIncludes Anvil\u003c\/strong\u003e: Yes\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: 0.5 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542406201650,"sku":"56323","price":452.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/239c98d751b6d1089005c658e5fefe41.jpg?v=1785899898","url":"https:\/\/voomisupply.com\/products\/starrett-56323-screw-thread-micrometer-0-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
