It covers a measurement range of 0 to 2 inches with a graduation of 0.0001 inches and an accuracy of 0.000050 inches, making it suitable for applications where tight tolerances are critical. The ratchet stop thimble provides consistent measuring force, reducing operator-to-operator variation. Both the anvil and spindle measuring faces are solid carbide, which resists wear in production environments. A digital counter is integrated into the body for easy reading. This instrument is used by machinists, quality control technicians, and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 56156 is suited for precision measurement tasks in machine shops, fabrication facilities, and quality inspection departments. It handles outside dimensional checks on shafts, pins, bar stock, and machined components up to 2 inches. The ratchet stop thimble makes it appropriate for repetitive gauging where consistent spindle pressure is required. The satin chrome finish reduces glare under shop lighting. Includes a lock nut and wrench for securing the spindle position when transferring readings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 0 to 2 inches with 0.0001 inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.000050 inches for high-tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces on both anvil and spindle for extended service life\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures repeatable, consistent measuring force\u003c\/li\u003e\n  \u003cli\u003eIntegrated digital counter for fast, clear reading\u003c\/li\u003e\n  \u003cli\u003eRing-style lock nut included with wrench for spindle position retention\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces reflective glare in bright shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose outside micrometer for standard outside diameter and thickness measurements on components up to 2 inches in size across machining and inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOutside micrometers require no installation but should be calibrated and zeroed against a known standard before use. Store the instrument with a slight gap between the anvil and spindle to allow for thermal expansion. Avoid overtightening the lock nut, as this can introduce measurement error. Periodic cleaning of the spindle threads and measuring faces with a lint-free cloth maintains accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\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\u003eIncludes\u003c\/strong\u003e: Lock Nut and Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.625 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\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: 56156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51692454117682,"sku":"56156","price":524.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/614456f9abaeffee4f7a7672f5d66358.jpg?v=1788297727","url":"https:\/\/voomisupply.com\/products\/starrett-56156-outside-micrometer-2-inch-range","provider":"Voomi Supply","version":"1.0","type":"link"}
