Built from steel, this fixed-limit gage checks whether a drilled, reamed, or bored hole falls within an acceptable dimensional range. The nominal measurement diameter is 0.062 inches, with a tolerance of 0.0002 inches, placing it in the tight-tolerance ZZ Plus classification suited for quality control and incoming inspection work. Machinists, toolmakers, and quality technicians use plug gages like this one to verify hole size quickly and reliably without relying on variable measuring instruments.\u003c\/p\u003e\n\u003cp\u003eThis gage is appropriate for use in machine shops, precision manufacturing facilities, and inspection departments where small-diameter hole verification is a routine part of the workflow. The 0.062-inch diameter makes it well suited for checking small drilled or reamed holes in metal, plastic, or composite workpieces. It is a single-ended fixed-limit gage intended for go or no-go inspection work at the bench or on the floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.062 inches for small-hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy bench or floor use\u003c\/li\u003e\n  \u003cli\u003eFixed-limit design allows fast pass or fail hole checks without calculation\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 any inspection application requiring a 0.062-inch diameter fixed-limit gage conforming to Class ZZ Plus tolerance standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, clean the gage and the hole being checked with a lint-free cloth to remove chips, coolant, or debris that could affect the measurement. Apply light gaging oil when checking steel workpieces to reduce wear on the gage land. Store the gage in its protective case when not in use to maintain calibration and surface condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-062-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692467618098,"sku":"29-062-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7623746a1eb51e4824635218d70cdc51.jpg?v=1788297979","url":"https:\/\/voomisupply.com\/products\/spi-29-062-7-class-zz-plus-plug-gage-0-062-in","provider":"Voomi Supply","version":"1.0","type":"link"}
