This 84-piece set is used to verify hole sizes, slot widths, and inter-hole distances with a high degree of dimensional repeatability. Each steel pin is manufactured to NIST-traceable standards, making the set suitable for quality control and inspection workflows where documented accuracy is required. A certificate of accuracy and a pin gage holder are included. Dimensional inspection technicians, machinists, and quality assurance professionals are the primary users of this type of tooling.\u003c\/p\u003e\u003cp\u003eThis plug gage set is used in production and inspection environments where quick, accurate measurement of drilled, reamed, or bored holes is required. The 84-piece configuration spans a range from 0.833 to 0.916 inches, providing coverage for a wide variety of workpiece features in a single kit. It is appropriate for both incoming material inspection and in-process quality checks across light manufacturing, machining, and precision fabrication settings. The included pin gage holder keeps pins organized and accessible during use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance rating with 0.0002 inch minus tolerance per pin\u003c\/li\u003e\n\u003cli\u003eRange of 0.833 to 0.916 inches covered across 84 steel pins\u003c\/li\u003e\n\u003cli\u003eNIST-traceable certificate of accuracy included with each set\u003c\/li\u003e\n\u003cli\u003eSuitable for hole size verification, slot width measurement, and NO-GO gaging inspection\u003c\/li\u003e\n\u003cli\u003ePin gage holder included for organized storage and field use\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in shop and inspection room environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard pin gage holders and inspection fixtures that accept pins in the 0.833 to 0.916 inch diameter range.

Clean pins and the workpiece hole before gaging to avoid false readings caused by debris or coolant residue. Do not force pins into undersized holes, as this can damage the pin and alter its calibrated diameter. Recalibration against NIST-traceable standards is recommended periodically or after any suspected impact or damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.833 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.916 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 Type\u003c\/strong\u003e: Minus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: ZZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 84\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Traceable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.83 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 12.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 17.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 34.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 22-152-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701549269298,"sku":"22-152-3","price":556.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f62446f161e28826479f42aa6c64d94d.jpg?v=1788401196","url":"https:\/\/voomisupply.com\/products\/spi-22-152-3-class-zz-plug-gage-set-0-833-0-916-in-84-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
