Built to Class ZZ Plus tolerances of 0.0002 inches, this gage provides a reliable reference standard for verifying inside diameter dimensions in production and quality-control environments. Constructed from steel for durability and dimensional stability, it is used by machinists, quality technicians, and toolroom professionals who require consistent, repeatable measurement results during part inspection and process verification.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for general manufacturing inspection tasks involving small-diameter holes in machined components. It is well matched to job shops, production floors, and metrology labs where Class ZZ Plus accuracy is specified for medium-tolerance work. The compact size and single-piece construction make it easy to handle during high-volume inspection routines or periodic quality audits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus accuracy with 0.0002 inch tolerance for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.238 inch nominal measurement diameter for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece plug gage format for straightforward go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy one-handed use during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for Class ZZ Plus inspection applications requiring a 0.238 inch diameter measurement reference in standard steel gage programs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists trained in dimensional metrology. Clean the gage and the bore being checked before use to remove chips, coolant, or debris that could affect the reading. Do not force the gage into an undersized bore, as this can damage the gage land or the workpiece. Store the gage in a protective case away from abrasive surfaces to preserve the tolerance condition of the measuring surface.\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: 0.238 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: 29-238-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692643877170,"sku":"29-238-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f453839888bb9db6594b82f17520a76c.jpg?v=1788300483","url":"https:\/\/voomisupply.com\/products\/spi-29-238-3-class-zz-plus-plug-gage-0-238-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
