Manufactured from tool steel with a 10 micro finish, it holds a tolerance of 0.00508 mm, making it suitable for verifying hole acceptance in precision machining and quality-control environments. The gage ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this type of gage in production floor inspection and calibration workflows.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in applications requiring go-style inspection of cylindrical holes at the 19.31 mm nominal diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices where a traceable, known-diameter reference is required. Typical environments include machine shops, tool rooms, and quality inspection stations in both job-shop and production manufacturing settings. The tight Class ZZ Plus tolerance class makes it appropriate for close-tolerance work where dimensional conformance must be documented.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade with 0.00508 mm tolerance for precise go inspection\u003c\/li\u003e\n  \u003cli\u003e19.31 mm nominal diameter in tool steel construction\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish for consistent, repeatable contact\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 standards for gage calibration and dimensional verification\u003c\/li\u003e\n  \u003cli\u003eCompatible with go inspection setups and as a reference for micrometers, verniers, and other measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 19.31 mm diameter holes and for use as a reference standard when setting micrometers, verniers, and other measuring devices in machine shop and quality-control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality technicians; no installation in the traditional sense applies. Store the gage in its protective case and keep it clean and lightly oiled to prevent corrosion of the tool steel. Do not force the gage into an undersized hole, as this can damage the gage or cause inaccurate readings. Recalibrate or recheck the gage periodically per your quality system requirements to maintain NIST-traceable accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 19.31 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 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\u003eWeight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: 10 Micro\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Go Inspection; Setting Micrometers, Verniers, and Other Measuring Devices\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\u003eStandards\u003c\/strong\u003e: ASME B89.1\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: 112319310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51737306595634,"sku":"112319310","price":20.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_7507a8ca-94f0-4776-861f-c5297352d47f.jpg?v=1788786894","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112319310-class-zz-plus-plug-gage-19-31mm","provider":"Voomi Supply","version":"1.0","type":"link"}
