Plug gages of this class are used to verify bore and hole dimensions by confirming whether a feature falls within its specified tolerance limits. The Class ZZ designation indicates a working-grade gage suitable for production inspection environments. Constructed from steel, this gage provides the hardness and dimensional stability required for repeatable go\/no-go measurement tasks in precision machining and quality control workflows. It is handled by machinists, quality technicians, and toolroom personnel.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting small-diameter holes and bores in production or toolroom settings. At 0.081 inches nominal diameter, it targets fine-pitch features common in precision components across manufacturing, instrumentation, and mechanical assembly applications. It is used as a working gage in standard attribute inspection setups where rapid pass\/fail decisions are needed at the point of production.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.081 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable working-grade accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual toolroom or bench use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy one-handed handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working-grade plug gage for use in standard go\/no-go attribute inspection of holes and bores nominally sized at 0.081 inches across compatible gage handle systems and direct-use toolroom applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by quality control technicians and machinists during inspection operations. Ensure the gage and workpiece are at the same ambient temperature before measuring to avoid thermal expansion errors. Do not force the gage into a bore; apply only light, consistent hand pressure to prevent premature wear or damage to the gage or workpiece. Store the gage in a protective case or sleeve when not in use to maintain its calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.081 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: 29-081-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693156729138,"sku":"29-081-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc213d30c6d411231910d591f005dbdb.jpg?v=1788308149","url":"https:\/\/voomisupply.com\/products\/spi-29-081-7-class-zz-plus-plug-gage-0-081-in","provider":"Voomi Supply","version":"1.0","type":"link"}
