It measures a nominal diameter of 0.553 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go verification of machined holes where tight dimensional control is required. Constructed from steel for durability and dimensional stability, this gage is used by quality control technicians, machinists, and tooling specialists who need reliable, repeatable measurement of hole diameters in production settings.\u003c\/p\u003e\u003cp\u003eThis plug gage is used in machine shops, manufacturing facilities, and inspection departments for verifying bore diameters to a Class ZZ Plus standard. It is appropriate for incoming inspection, in-process quality checks, and final acceptance testing of machined components. The 0.553-inch diameter makes it a precise fit for applications requiring verification of that specific nominal bore size across a range of part geometries and materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ Plus tolerance class for precision bore measurement and go\/no-go inspection\u003c\/li\u003e\n\u003cli\u003e0.553-inch nominal measurement diameter for accurate hole verification\u003c\/li\u003e\n\u003cli\u003e0.0002-inch tolerance ensures tight dimensional control\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and long service life\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.2 pounds for comfortable handheld use during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a precision inspection tool for verifying machined bores at a nominal diameter of 0.553 inches in general manufacturing and quality control applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists rather than installed in a system. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage and the bore being measured before use to avoid false readings caused by debris or residue. Follow your facility's gage calibration and handling procedures to maintain measurement integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.553 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\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: 29-553-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":67951968452914,"sku":"29-553-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2313e9070806332e5ec0cb38de29a3e0.jpg?v=1791742709","url":"https:\/\/voomisupply.com\/products\/spi-29-553-5-class-zz-plus-plug-gage-0-553-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
