It is manufactured from steel and holds a tolerance of 0.0002 inches, making it suitable for dimensional inspection work in machine shops, toolrooms, and production environments. Machinists, quality control technicians, and precision manufacturing professionals use plug gages to confirm that drilled, reamed, or machined holes fall within acceptable specification limits. The Class ZZ Plus designation indicates this gage meets go\/no-go inspection standards appropriate for general-purpose dimensional verification.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for use in shop-floor and inspection-room applications where small-diameter hole verification is required. It is well suited to checking holes in machined components, fixtures, and assemblies where tight tolerances must be confirmed before parts advance in a production process. The 0.129-inch nominal diameter makes it applicable to small-bore work common in precision machining and light manufacturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.129 inches for small-bore hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for general-purpose dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSold as an individual unit with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Plus plug gage for verifying bored, drilled, or reamed holes with a nominal diameter of 0.129 inches in machined components and assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians and do not require installation in the traditional sense. Before use, clean the gage and the hole being checked to remove chips, oil, and debris that could affect the measurement reading. Do not force a plug gage into an undersized hole, as this can damage the gage surface and compromise its accuracy. Store the gage in a protective case away from abrasive materials to maintain its tolerance rating over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.129 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\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: 29-129-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690692772146,"sku":"29-129-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7af2bb3887eb791ae30648255e58c9c.jpg?v=1788274045","url":"https:\/\/voomisupply.com\/products\/spi-29-129-4-class-zz-plus-plug-gage-0-129-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
