Built from steel, this go\/no-go style gage checks a nominal diameter of 0.433 inches with a tolerance of 0.0002 inches, making it suitable for applications where tight dimensional control is required. Machinists, quality technicians, and tool-room professionals use plug gages like this to confirm that machined bores fall within specification before parts advance to the next stage of production or assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and quality inspection stations. It is appropriate for checking holes in metal components where a 0.433-inch nominal bore diameter must be confirmed to specification. The Class ZZ Plus designation indicates a commercial-grade tolerance class commonly used for general production inspection work rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.433 inches for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus classification requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy hand use during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual or small-lot procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use plug gage for any application requiring inspection of a 0.433-inch nominal bore diameter at Class ZZ Plus tolerance.

Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect the reading. Allow both the gage and the workpiece to reach the same ambient temperature, typically 68 degrees F per ASME B89 standards, before performing inspection to avoid thermal expansion errors. Do not force the gage into the bore; if resistance is felt, the bore is undersize and should be returned for additional machining.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.433 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: 29-433-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714905768242,"sku":"29-433-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a666d4cd631122aebc51c7b830a1805.jpg?v=1788507703","url":"https:\/\/voomisupply.com\/products\/spi-29-433-0-class-zz-plus-plug-gage-0-433-in","provider":"Voomi Supply","version":"1.0","type":"link"}
