It covers a 0 to 3 inch measurement range with a 0.001 inch graduation, giving technicians and machinists the resolution needed for accurate surface, runout, and alignment checks. The 2-1\/4 inch white dial face uses a 0-100 dial reading with a revolution counter to track cumulative travel. The indicator features a jeweled bearing, a stainless steel stem measuring 0.375 inches in diameter and 2.8125 inches in length, and an unbreakable crystal with a no-glare satin finish for clear readings in varied lighting conditions.\u003c\/p\u003e\n\u003cp\u003eThis indicator is suited for use in machine shops, tool rooms, quality control stations, and field alignment work. It mounts via a lug back and ships with a flat back included, giving installers flexibility in fixture setup. The 0.1 inch travel per revolution keeps reading transitions predictable during inspection routines. It is appropriate for use with standard indicator holders and magnetic base setups common in precision trade environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 3 inch measurement range with 0.001 inch graduation for high-resolution readings\u003c\/li\u003e\n  \u003cli\u003eJeweled bearing construction for smooth, repeatable stem travel\u003c\/li\u003e\n  \u003cli\u003eRevolution counter tracks total stem travel across the full 3 inch range\u003c\/li\u003e\n  \u003cli\u003eLug back mount included with flat back adapter for flexible fixture options\u003c\/li\u003e\n  \u003cli\u003eUnbreakable crystal with no-glare satin finish for clear viewing in shop conditions\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem, 0.375 inches in diameter and 2.8125 inches in length\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 and flat back indicator holders, magnetic bases, and dial indicator fixtures used in precision measurement and inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, metrologists, or precision trade professionals using standard indicator mounting hardware. Secure the indicator firmly in the holder before zeroing to prevent movement during measurement. Avoid side-loading the stem, as this can affect accuracy and bearing life. Always zero the indicator at the reference surface before taking readings.\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 3 inches\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\u003eDial Diameter\u003c\/strong\u003e: 2-1\/4 inches\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\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 2.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug (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\u003eDial Color\u003c\/strong\u003e: White\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.375 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: 53310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539501220146,"sku":"53310","price":613.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35feaca477067e38fb8e5cfa976f65b1.jpg?v=1785841914","url":"https:\/\/voomisupply.com\/products\/starrett-53310-dial-drop-indicator-0-3-in-0-001-grad","provider":"Voomi Supply","version":"1.0","type":"link"}
