It measures a nominal diameter of 0.087 inches with a tolerance of 0.0002 inches, making it suitable for tight-tolerance quality control work. Machined from steel, this plug gage provides the rigidity and wear resistance required for production floor or inspection bench use. Metrology technicians, machinists, and quality control inspectors use this tool to verify hole dimensions quickly and accurately without specialized measuring equipment.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for applications involving precision-machined components where bore diameter verification is required. The 0.087-inch diameter range fits small-bore inspection tasks common in aerospace, automotive, and general manufacturing environments. Its compact size allows use in tight or recessed features. The Class ZZ Plus designation indicates it meets industry standards for working gages used in production inspection rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.087-inch nominal measurement diameter for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for high-accuracy dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus designation meets standard working gage classifications\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for small or recessed bore features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working plug gage for go\/no-go inspection of bores and holes at 0.087-inch nominal diameter in production and quality control settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists or quality control inspectors and do not require installation in the traditional sense. Store the gage in a clean, dry case when not in use to prevent corrosion and damage to the ground surfaces. Handle with care to avoid dropping, which can alter the gage diameter and invalidate its calibration. Recalibrate or verify against a certified master gage at intervals appropriate to your quality management system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.087 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  \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: 29-087-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689481044274,"sku":"29-087-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26c2b17bac924301f78787e95f0af55b.jpg?v=1788260125","url":"https:\/\/voomisupply.com\/products\/spi-29-087-4-class-zz-plus-plug-gage-0-087-in","provider":"Voomi Supply","version":"1.0","type":"link"}
