Built to Class ZZ Plus tolerance standards, it holds a tolerance of 0.0002 inches, making it suitable for production-floor inspection where consistent, repeatable measurement is required. The gage body is constructed from steel for durability and wear resistance under regular shop use. Machinists, toolroom technicians, and quality control inspectors use plug gages like this one to verify hole diameter conformance during in-process and final inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever precise hole diameter verification is required in metalworking, fabrication, and machining environments. Typical applications include inspection of drilled, reamed, or bored holes in production parts. It is well suited for both job shop and high-volume manufacturing inspection stations where a reliable, hand-held attribute gage is needed to confirm dimensional compliance quickly and without complex setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for precise dimensional inspection\u003c\/li\u003e\n  \u003cli\u003e0.873 inch nominal diameter measurement range\u003c\/li\u003e\n  \u003cli\u003eSteel construction for shop-floor durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy hand-held use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package ready for immediate deployment in inspection workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for go\/no-go inspection of holes with a 0.873 inch nominal diameter in general metalworking and machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality technicians and require no permanent installation. Clean both the gage and the workpiece bore before use to avoid false readings caused by chips or coolant residue. Do not force the gage into a hole; excessive insertion force can damage the gage or the workpiece and will skew inspection results. Store the gage in a protective case away from heat sources and contaminants to preserve calibration and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.873 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-873-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700218462514,"sku":"29-873-7","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89216b8e90f6cd39d1d28c3c6617a22f.jpg?v=1788387752","url":"https:\/\/voomisupply.com\/products\/spi-29-873-7-class-zz-plus-plug-gage-0-873-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
