It covers a measurement range of 0 to 1 inch with a graduation of 0.001 inches per division and a 0-100 dial reading, allowing technicians to resolve fine deviations quickly. The 2.75-inch white dial face carries a no-glare satin finish and is protected by an unbreakable crystal. The stainless steel stem measures 0.375 inches in diameter and 0.625 inches in length. A built-in revolution counter tracks full spindle rotations, reducing reading errors during extended measurement runs. The unit weighs 1 pound and ships with a flat back included.\u003c\/p\u003e\n\u003cp\u003eThis indicator is suited for use on surface plates, magnetic bases, and indicator holders in machine shop, tool-and-die, and quality-control environments. It is appropriate for both production floor inspection and setup work where consistent, repeatable readings are required. The lug back mount allows direct attachment to standard indicator holders and arms. The jeweled bearing construction supports long service life under regular shop use. Machinists, metrologists, and quality technicians install this type of indicator for runout checks, flatness verification, and workpiece alignment tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 1 inch measurement range with 0.001 inch graduation for high-resolution readings\u003c\/li\u003e\n  \u003cli\u003eJeweled bearing construction for smooth spindle travel and extended service life\u003c\/li\u003e\n  \u003cli\u003eRevolution counter tracks full spindle rotations for accurate multi-revolution readings\u003c\/li\u003e\n  \u003cli\u003eNo-glare satin finish on 2.75-inch white dial for clear readability under shop lighting\u003c\/li\u003e\n  \u003cli\u003eUnbreakable crystal protects dial face from impact and debris\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem resists corrosion in wet or coolant-exposed environments\u003c\/li\u003e\n  \u003cli\u003eLug back mount with flat back included for versatile fixture compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style drop indicator compatible with standard lug back indicator holders, magnetic bases, and surface gauge arms commonly used in machine shop and inspection environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, metrologists, or quality technicians using a compatible indicator holder or magnetic base that accepts a lug back mount. Secure the lug back firmly before taking measurements to prevent indicator movement that would affect reading accuracy. Ensure the spindle axis is aligned perpendicular to the measurement surface to obtain valid readings. Do not overtighten clamping hardware against the stem or bezel, as this can introduce preload errors or damage the mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.75 inches (69.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches (9.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 0.625 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug Back (Flat Back Included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Jeweled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal\u003c\/strong\u003e: Unbreakable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: No-Glare Satin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: English\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAGD Group\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 53613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542110044466,"sku":"53613","price":339.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d6d5516eee8e7901c9dd64c40c7fd08.jpg?v=1785892351","url":"https:\/\/voomisupply.com\/products\/starrett-53613-dial-drop-indicator-0-1-in-0-001-grad-lug-back","provider":"Voomi Supply","version":"1.0","type":"link"}
