It measures a nominal diameter of 0.175 inches with a tolerance of 0.0002 inches, making it suitable for precision quality-control checks on machined components. The gage is constructed from steel for durability in shop environments. Machinists, quality technicians, and toolroom professionals use plug gages like this one to verify that drilled, reamed, or bored holes fall within specified dimensional limits without the need for expensive measuring instruments at the point of inspection.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, manufacturing facilities, and toolrooms wherever tight-tolerance hole inspection is required. The Class ZZ Plus designation indicates it meets established gage tolerance standards appropriate for general inspection of production parts. It is well suited for incoming inspection, in-process quality checks, and final part verification on components with 0.175-inch nominal bore features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.175 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for precise go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus classification meets standard inspection gage requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability in production shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact single-piece design for fast, repeatable hole checks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use inspection gage for any machined component, fixture, or assembly requiring verification of a 0.175-inch nominal diameter bore or hole feature.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians. Before use, clean both the gage and the hole being inspected to remove chips, coolant, and debris that could affect readings or damage the gage surface. Do not force the gage through a hole; excessive insertion force can damage the gage or the workpiece and will invalidate the measurement. Store the gage in its protective case when not in use to prevent surface damage and 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\u003eMeasurement Diameter\u003c\/strong\u003e: 0.175 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: 29-175-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720484421938,"sku":"29-175-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f26ba48e7309a2f3fe6dfbcd5ea70adf.jpg?v=1788564784","url":"https:\/\/voomisupply.com\/products\/spi-29-175-7-class-zz-plus-plug-gage-0-175-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
