With a nominal diameter of 0.037 inches and a minus tolerance of 0.000200 inches, this gage provides a reliable go\/no-go reference for quality control checks on small-diameter features. Constructed from steel, the 19-037-1 is built to handle repeated use in shop floor and inspection room environments. It is typically used by machinists, toolmakers, and quality technicians who need consistent dimensional verification on tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for checking small bores in precision-machined components across manufacturing, aerospace, automotive, and general metalworking applications. The Class ZZ designation indicates it meets standard tolerance requirements for inspection-grade gaging. The minus designation means the gage is ground to the lower boundary of the tolerance band, making it appropriate for specific go or no-go inspection roles depending on the application setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.037 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance grade at 0.000200 inches for inspection-grade accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact single-pin format for easy handling and storage\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 1 for individual replacement or addition to existing gage sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage suitable for use in general inspection and quality control applications requiring verification of 0.037-inch diameter bores and holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by quality technicians and machinists and require no installation in the traditional sense, but proper handling is essential for accurate results. Keep the gage clean and lightly oiled when not in use to prevent corrosion and wear. Never force a plug gage into a bore; light hand pressure is the correct method to avoid damage to the gage or the workpiece. Store individually or in a dedicated gage block case to protect the ground surface from nicks and contamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.037 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.000200 inches (minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19-037-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692419744050,"sku":"19-037-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da972979b28c1083c54f91dde18705a6.jpg?v=1788297282","url":"https:\/\/voomisupply.com\/products\/spi-19-037-1-class-zz-minus-plug-pin-gage-0-037-in","provider":"Voomi Supply","version":"1.0","type":"link"}
