Manufactured from steel, this go\/no-go style gage delivers a tolerance of 0.0002 inches, making it suitable for precision inspection work in machine shops, manufacturing facilities, and production environments. Metrology technicians and quality control inspectors use plug gages like this to confirm dimensional conformance during in-process or final inspection. The Class ZZ Plus designation reflects a defined tolerance grade appropriate for general-purpose gauging of production parts.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in applications requiring accurate verification of small-diameter holes. It fits into quality inspection workflows for machined components, drilled passages, and precision assemblies where hole size must meet tight specifications. The 0.171-inch nominal diameter targets a specific size range common in precision metalworking and light manufacturing. Its compact size and steel construction make it practical for both bench and floor inspection use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.171 inches for precise hole verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus grade requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability for repeated use in production environments\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suits bench inspection and in-line quality checks\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with a minimum order quantity of 1\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 inspection of 0.171-inch nominal diameter holes in machined parts and precision assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by metrology or quality control personnel, not installed in a mechanical system. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove debris, oils, or chips that could affect measurement accuracy. Apply light gage oil when appropriate to reduce wear on the gage surface. Follow your facility calibration schedule and handle the gage carefully to avoid dropping or contact with abrasive surfaces, which can alter the precision ground diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.171 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Metric)\u003c\/strong\u003e: 0.0002 mm\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: 29-171-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51712717291826,"sku":"29-171-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/591058da6b43be9b991a86790f6b4550.jpg?v=1788488183","url":"https:\/\/voomisupply.com\/products\/spi-29-171-6-class-zz-plus-plug-gage-0-171-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
