It checks a nominal hole diameter of 0.16 inches with a tolerance of 0.0002 inches, providing reliable go\/no-go inspection capability for precision machining and quality control applications. Constructed from steel, this gage delivers the hardness and wear resistance expected in production measurement environments. Machinists, quality technicians, and tool room personnel use plug gages like the 29-160-9 to confirm that hole sizes fall within specification before parts advance to the next stage of fabrication or assembly.\u003c\/p\u003e\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and tool rooms where tight-tolerance hole inspection is required. It is appropriate for both low-volume prototype work and higher-volume production runs where consistent hole sizing must be verified. The 0.16-inch diameter makes it applicable to small-bore inspection tasks common in precision component manufacturing, instrumentation, and light mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ Plus tolerance classification for hole diameter verification\u003c\/li\u003e\n\u003cli\u003eNominal measurement diameter of 0.16 inches\u003c\/li\u003e\n\u003cli\u003eTolerance of 0.0002 inches for precise go\/no-go inspection\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for small-bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style plug gage for inspecting holes with a nominal diameter of 0.16 inches in standard Class ZZ Plus tolerance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality technicians and machinists and do not require power-down procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a hole; smooth insertion and withdrawal indicate proper fitment. Store in a protective case away from temperature extremes to maintain calibration accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.16 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 (mm)\u003c\/strong\u003e: 0.0002 mm\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 29-160-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689591406898,"sku":"29-160-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b68a7552d810f38418c49d1b0172615b.jpg?v=1788261520","url":"https:\/\/voomisupply.com\/products\/spi-29-160-9-class-zz-plus-plug-gage-0-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
