It measures a nominal diameter of 0.134 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go\/no-go inspection work. The gage is constructed from steel for durability and dimensional stability under repeated use. Machinists, tool-and-die technicians, and quality inspectors use plug gages like this one to verify that drilled, reamed, or bored holes fall within specified tolerance ranges before parts advance in the production process.\u003c\/p\u003e\n\u003cp\u003eThis gage is intended for use in precision inspection of small-diameter bores in production and job-shop settings. Its compact size and fine tolerance class make it appropriate for inspecting holes in metal components where tight dimensional control is required. Class ZZ Plus gages are typically used as working gages on the shop floor for routine inspection tasks rather than as master or reference gages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.134-inch nominal diameter for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance meets Class ZZ Plus accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package — ready for immediate use out of the box\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suits tight-clearance inspection applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working plug gage for go\/no-go inspection of 0.134-inch nominal diameter bores in standard machining and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists or quality inspectors — no power shutoff is required. Store the gage in a protective case away from heat sources and abrasive surfaces to prevent dimensional distortion. Clean the gage and the bore to be measured before use to remove chips, coolant, and debris that could affect the reading. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.134 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  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-134-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696686006578,"sku":"29-134-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11fd2484c3d2eb80bebe66a5841291e7.jpg?v=1788345228","url":"https:\/\/voomisupply.com\/products\/spi-29-134-4-class-zz-plus-plug-gage-0-134-in","provider":"Voomi Supply","version":"1.0","type":"link"}
