Built to a nominal diameter of 0.976 inches with a tolerance of 0.0002 inches, this gage provides reliable go\/no-go verification of machined holes and bored features. The steel construction ensures durability under repeated use in shop-floor conditions. Machinists, toolroom technicians, and quality inspectors rely on Class ZZ plug gages for maintaining dimensional accuracy on production parts and inspection samples.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for verifying hole diameters in precision machined components across light manufacturing and heavy industry applications. It is used at inspection stations, on the shop floor, and in toolrooms where consistent, repeatable measurement is required. The 0.976-inch nominal size covers a common bore dimension found in shaft fits, bearing bores, and drilled or reamed hole inspection. The compact, single-piece design integrates easily into standard plug gage handles or holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.976 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for dependable go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact single-piece gage member compatible with standard plug gage handles\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during repeated inspection cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inspection tool for use with standard plug gage handles and holders accepting members in the 0.976-inch diameter range.

Before use, clean the gage member and the bore being measured to remove chips, coolant, and debris that can affect readings. Handle with clean dry hands or lint-free gloves to prevent corrosion from skin contact. Store in a protective case away from other tooling to prevent surface damage that could compromise dimensional accuracy.\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\u003eNominal Diameter\u003c\/strong\u003e: 0.976 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-976-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695453339954,"sku":"29-976-8","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d31c4e5caa7f9b515ce51ba845cddfd3.jpg?v=1788335228","url":"https:\/\/voomisupply.com\/products\/spi-29-976-8-class-zz-plus-plug-gage-0-976-in","provider":"Voomi Supply","version":"1.0","type":"link"}
