It covers a measuring range of 0 to 0.25 inches with a dial graduation of 0.001 inches, giving technicians clear, repeatable readings on a 0-50-0 dial face. The 1-11\/16 inch diameter white dial carries a no-glare satin finish and is protected by an unbreakable crystal. A jeweled bearing mechanism supports smooth stylus travel, and the stainless steel stem adds durability in shop environments. The built-in revolution counter tracks full stem cycles, reducing read errors during longer measurements.\u003c\/p\u003e\u003cp\u003eThe 53400 suits precision alignment, runout checks, surface flatness verification, and fixture setup work in machining, fabrication, and maintenance trades. The lug back mount makes it easy to attach to magnetic bases, transfer arms, and indicator holders commonly used on mills, lathes, and surface plates. A flat back is included in the package for setups that require a flat-mounted configuration. The sharp bezel and rugged construction hold up to repeated handling in production and field service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasuring range of 0 to 0.25 inches with 0.001 inches graduation for fine displacement readings\u003c\/li\u003e\n\u003cli\u003e0-50-0 balanced dial reading for bidirectional measurement without resetting the indicator\u003c\/li\u003e\n\u003cli\u003e0.1 inches of travel per revolution keeps readings easy to track across the dial face\u003c\/li\u003e\n\u003cli\u003eJeweled bearing for smooth, consistent stylus movement and long service life\u003c\/li\u003e\n\u003cli\u003eNo-glare satin finish white dial with unbreakable crystal for clear visibility\u003c\/li\u003e\n\u003cli\u003eLug back included; flat back also included for flexible mounting options\u003c\/li\u003e\n\u003cli\u003eStainless steel stem resists corrosion in wet or coolant-exposed environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style dial drop indicator compatible with standard lug-back and flat-back indicator holders, magnetic bases, and transfer arms accepting a 0.375 inch stem diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup are typically performed by machinists, metrology technicians, or maintenance mechanics. Before mounting, ensure the indicator holder or magnetic base is firmly locked and the workpiece or machine spindle is stationary. Secure the lug back or flat back attachment snugly to prevent indicator slippage during measurement. Do not exceed the stated 0.25 inch travel range, as overtravel can damage the internal mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 0 to 0.25 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: 0-50-0\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: 1-11\/16 inches (42.86 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 1.0938 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches (82.00 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\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\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: English\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.438 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 53400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544488771890,"sku":"53400","price":255.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2be35f9dd24535119927b3a36053ba0.jpg?v=1785927860","url":"https:\/\/voomisupply.com\/products\/starrett-53400-dial-drop-indicator-0-to-0-25-in-range","provider":"Voomi Supply","version":"1.0","type":"link"}
