It features a 0-50 dial reading with 0.010 mm graduations and a full measurement range of 0 to 5.00 mm, delivering an accuracy of 0.013 mm. The lug back mount allows for secure fixture attachment on magnetic bases, surface plates, and inspection stands. A revolution counter tracks full-cycle travel, and the glare-free, scratch-resistant crystal keeps the white dial readable in shop and lab environments alike. Licensed HVAC techs, machinists, metrologists, and QC inspectors are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThe 1045A is suited for residential and commercial machine shop environments, tool and die work, and production-line inspection setups where repeatable drop-style measurement is required. The 8.00 mm stem diameter and 13.00 mm stem length fit standard indicator holders and dovetail clamps. The 40.00 mm dial diameter provides clear reading at typical bench-top working distances. Green limit markers are included for fast pass\/fail visual checks during repetitive inspection runs. This indicator conforms to ISO\/JIS standards and is classified under UNSPSC code 41111630.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 5.00 mm measurement range with 0.010 mm dial graduations\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.013 mm for reliable precision inspection\u003c\/li\u003e\n  \u003cli\u003eRevolution counter for tracking full-cycle spindle travel\u003c\/li\u003e\n  \u003cli\u003eGlare-free, scratch-resistant crystal over a white 40.00 mm dial\u003c\/li\u003e\n  \u003cli\u003eLug back mount for compatibility with standard indicator holders and fixtures\u003c\/li\u003e\n  \u003cli\u003eIncludes green limit markers and protective plastic case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric dial drop indicator conforming to ISO\/JIS standards, suitable for use with standard 8.00 mm stem indicator holders, magnetic bases, and surface plate fixtures common in machine shop and quality inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, metrologists, or QC technicians using standard indicator holders and clamping hardware. Secure the lug back to a rigid fixture before zeroing the dial to avoid measurement error from vibration or movement. Do not overtighten the stem clamp, as this can distort the stem and affect spindle travel. Zero the indicator against a reference surface before taking measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.00 to 5.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.010 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.013 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 1.40 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 13.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5 x 0.45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\/JIS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1045A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557424398642,"sku":"1045A","price":142.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/759706b70f0291651059c32fe2fd32d5.jpg?v=1786387723","url":"https:\/\/voomisupply.com\/products\/mitutoyo-1045a-dial-drop-indicator-0-50-lug-back-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
