Machined from steel, this gage is used for go\/no-go inspection of small-diameter features in precision manufacturing and metrology applications. Class ZZ Plus designates a tighter tolerance grade than standard Class ZZ, making it appropriate for quality control work where dimensional accuracy is critical. Machinists, toolroom inspectors, and quality technicians rely on plug gages like this one to confirm that drilled, reamed, or punched holes meet specification before parts advance through the production process.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspection of small-bore features in precision machined components, stamped parts, and fabricated assemblies. It is commonly used in job shops, production facilities, and metrology labs where consistent, repeatable hole verification is required. The compact size makes it appropriate for tight-clearance features and fine tooling work where standard gaging equipment may not reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.034 inches for precise small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual or bench-level inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or supplemental plug gage for Class ZZ Plus applications requiring a 0.034-inch nominal bore diameter check.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by quality technicians and toolroom personnel, not typically installed by a trade contractor. Before use, clean the gage and the bore being checked to remove chips, coolant, or debris that could affect measurement accuracy. Do not force the gage into an undersized hole, as this will damage the gage surface and compromise future readings. Store in a protective case away from moisture and temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.034 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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: 29-034-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693299466546,"sku":"29-034-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14e6ede2ba5522e9189343428765551f.jpg?v=1788310315","url":"https:\/\/voomisupply.com\/products\/spi-29-034-6-class-zz-plus-plug-gage-0-034-in","provider":"Voomi Supply","version":"1.0","type":"link"}
