Machined from tool steel and finished to a 10 microfinish surface, it provides repeatable, traceable measurement results in precision inspection environments. The gage diameter is 7.55 mm with a tolerance of 0.005 mm (0.00508 mm per ASME B89.1), making it suitable for tight-tolerance hole verification. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to national measurement standards. Licensed metrologists, quality technicians, and toolroom machinists are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for go inspection of 7.55 mm diameter bores in production or toolroom settings. It is also suitable for setting and checking micrometers, verniers, and other measuring devices that require a calibrated reference standard. Typical applications include incoming inspection, in-process quality control, and calibration support in manufacturing facilities handling precision-machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade per ASME B89.1 for precision bore inspection\u003c\/li\u003e\n  \u003cli\u003e7.55 mm diameter with 0.005 mm tolerance for tight-tolerance go inspection\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent, low-wear contact with the workpiece\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e2.0000-inch overall length for standard handle compatibility\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a go inspection plug gage for 7.55 mm diameter bores.

Store the gage in its protective case and apply a light coat of instrument oil when not in use to prevent corrosion. Do not force the gage into undersized bores, as this can damage the gage surface and affect calibration. Recalibrate periodically in accordance with your facility quality management plan and ASME B89.1 requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7.55 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 mm (0.00508 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Accuracy with NIST Traceability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 112307550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51735276388658,"sku":"112307550","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e88df3d88469d3737f2848989bbcd906_08b81482-9447-4b0b-9358-96a733df4515.jpg?v=1788771393","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112307550-class-zz-plus-plug-gage-7-55mm","provider":"Voomi Supply","version":"1.0","type":"link"}
