These accessory jaws attach to standard rectangular gage blocks to enable precision radius and outside-diameter measurements. Each jaw features a 0.2-inch radius ground to a tolerance of 0.00003 inches, and the matched pair delivers a combined accuracy of 0.00004 inches. Overall jaw length is 1.965 inches with a jaw thickness of 0.315 inches. The set includes 2 pieces and is sold as a complete pair. Metrology technicians, tool room machinists, and quality control inspectors use these jaws when gage blocks alone cannot reach a required measurement application.\u003c\/p\u003e\n\u003cp\u003eThese cylindrical jaws are engineered for trade and industrial metrology environments where rectangular gage blocks are already in use. Typical applications include inspection rooms, tool cribs, and precision manufacturing facilities that require traceable, repeatable radius measurements. They are intended for use with standard rectangular gage block sets and expand the measurement capability of an existing gage block setup without requiring a dedicated instrument. The set weighs approximately 0.5 pounds and ships as a matched pair of 2 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.965-inch overall length for reach on standard rectangular gage blocks\u003c\/li\u003e\n  \u003cli\u003e0.315-inch jaw thickness provides a stable contact face\u003c\/li\u003e\n  \u003cli\u003e0.2-inch radius ground to 0.00003-inch tolerance per jaw\u003c\/li\u003e\n  \u003cli\u003eMatched pair accuracy of 0.00004 inches for traceable measurements\u003c\/li\u003e\n  \u003cli\u003eSold as a complete pair of 2 pieces — no additional components required\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for use with rectangular gage blocks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rectangular gage blocks as stated in the product specifications.

Ensure all contact surfaces are clean and free of burrs, oil, or debris before attaching jaws to gage blocks. Handle with clean, lint-free gloves or tools to preserve surface integrity and avoid corrosion from skin contact. Store in a protective case away from temperature extremes to maintain calibration accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Cylindrical Jaws\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.965 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Thickness\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadius\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadius Accuracy (per jaw)\u003c\/strong\u003e: 0.00003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePair Accuracy\u003c\/strong\u003e: 0.00004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Rectangular Gage Blocks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: MS170308015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689729229106,"sku":"MS170308015","price":237.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51a74818a42cd598ba67be0a19f67902.jpg?v=1788263570","url":"https:\/\/voomisupply.com\/products\/spi-ms170308015-cylindrical-gage-block-jaws-1-965-in","provider":"Voomi Supply","version":"1.0","type":"link"}
