It is built to Class ZZ Plus tolerance standards, which specify a dimensional tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work in production and quality-control environments. Constructed from steel, this plug gage delivers the hardness and wear resistance required for repetitive gauging operations. Machinists, quality technicians, and tool room personnel use this type of gage to confirm that drilled, reamed, or bored holes fall within specified dimensional limits before parts move to assembly or final inspection.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is appropriate for shop floor and inspection room use in metalworking, machining, and precision manufacturing environments. It is typically applied when checking hole diameters on workpieces produced to tight dimensional tolerances, including fixtures, housings, hydraulic components, and similar precision-machined parts. The 0.527-inch nominal diameter makes it a direct-fit inspection tool for holes held to that target dimension. Package quantity is one gage per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.527 inches for direct hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for precise go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and durability for repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package with a minimum order quantity of one unit\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, suited for handheld inspection tasks\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 use with any go\/no-go gage handle or holder that accepts the 0.527-inch diameter gage member, in accordance with applicable dimensional gauging standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists; no permanent installation is required. Before use, clean the gage member and the workpiece bore of chips, coolant, and debris to prevent false readings or gage damage. Do not force the gage member into an undersized hole, as this can damage the gage surface and affect calibration. Periodic recalibration against a certified master is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.527 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-527-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51703916101938,"sku":"29-527-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_b8f1eb40-cb19-4495-ba4f-c8b696eb7432.jpg?v=1788419436","url":"https:\/\/voomisupply.com\/products\/spi-29-527-9-class-zz-plus-plug-gage-0-527-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
