The gage measures a nominal diameter of 0.149 inches with a tolerance of 0.0002 inches, making it suited for applications where tight dimensional accuracy must be confirmed. Constructed from steel, it provides the durability and wear resistance expected in production and inspection environments. Machinists, quality technicians, and toolroom professionals use plug gages like this to perform go\/no-go style inspections or direct diameter verification on machined components.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is appropriate for use in machine shops, manufacturing facilities, and metrology labs where hole diameter conformance must be verified to close tolerances. It is sized for small-diameter bore inspection at 0.149 inches and is well suited for checking drilled, reamed, or bored holes in metal components. The compact form factor allows use in confined inspection scenarios where larger gaging tools would not fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class for reliable dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.149 inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompact design suited for small-bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard plug gage for inspection of 0.149 inch nominal diameter bores and holes in machined metal parts.

Before use, clean the gage and bore thoroughly to remove chips, coolant, or debris that could affect measurement accuracy. Apply light gage oil when appropriate to protect the gage surface and extend service life. Store the gage in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.149 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\u003eTolerance Class\u003c\/strong\u003e: Class 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: 29-149-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722209198386,"sku":"29-149-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d629179c3ada76a02e39ffeaf670629a.jpg?v=1788587435","url":"https:\/\/voomisupply.com\/products\/spi-29-149-2-class-zz-plus-plug-gage-0-149-in","provider":"Voomi Supply","version":"1.0","type":"link"}
