{"product_id":"spi-21-244-9-cone-contact-point-dial-indicator","title":"Spi 21-244-9 Cone Contact Point Dial Indicator","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe SPI 21-244-9 is a cone-style contact point designed for use with dial indicators. It threads onto the indicator spindle via a 4-48 thread and provides a precise, repeatable contact surface for measurement work. The cone tip geometry suits applications where a small, defined contact area is needed on flat or contoured workpiece surfaces. Made from black oxide steel, the point resists corrosion and wear under regular shop use. At 0.75 inches in contact point length and 1\/64 inch tip diameter, it fits the AGD Group 1 standard used across most bench and transfer-style dial indicators. Machinists, quality control technicians, and tool-and-die tradespeople use this type of accessory when swapping or replacing worn contact points in the field or at the bench.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for precision measurement setups in machine shops, inspection rooms, and production environments. It is compatible with AGD Group 1 dial indicators that accept a standard 4-48 threaded contact point. Typical applications include surface inspection, runout measurement, and feature location tasks where a cone tip provides better access or contact geometry than a flat or ball-style point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCone contact point style for defined tip contact on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e4-48 thread fits AGD Group 1 dial indicator spindles\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch tip diameter for precise, small-area contact\u003c\/li\u003e\n  \u003cli\u003e0.75 inch contact point length for standard reach applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide steel construction resists corrosion and wear\u003c\/li\u003e\n  \u003cli\u003eMeets AGD Group 1 industry designation for broad indicator compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with AGD Group 1 dial indicators that accept a 4-48 threaded contact point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact point replacement is typically performed by machinists or metrology technicians using a small wrench or contact point tool. Zero the indicator after installing a new contact point to confirm proper seating and eliminate any offset error. Do not overtighten the threaded point into the spindle, as this can damage the fine 4-48 thread. Follow the dial indicator manufacturer's instructions for contact point removal and installation procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Black Oxide Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Designation\u003c\/strong\u003e: AGD Group 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 21-244-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690390716722,"sku":"21-244-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3eeb00d0ece7dd7ce2b601c28b4697b2.jpg?v=1788269862","url":"https:\/\/voomisupply.com\/products\/spi-21-244-9-cone-contact-point-dial-indicator","provider":"Voomi Supply","version":"1.0","type":"link"}
