Manufactured from black oxide steel, this contact point features a 4-48 thread size and meets AGD Group 1 industry specifications. The tapered geometry provides accurate, repeatable contact on workpiece surfaces, making it a reliable replacement or spare for technicians and machinists who depend on dial indicator accuracy. With a contact point length of 0.5 inches and a diameter of 1\/64 inch at the tip, it is built for fine-tolerance measurement work where tip geometry directly affects reading accuracy.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for use in machine shops, tool rooms, and precision inspection environments. It threads directly onto AGD Group 1 dial indicators and is a standard replacement point for technicians performing dimensional inspection, runout checks, or surface comparisons. The black oxide steel construction provides corrosion resistance suitable for typical shop environments. Installation requires no special tooling beyond careful hand-threading to avoid cross-threading the fine 4-48 thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered contact point style for precise, repeatable surface contact\u003c\/li\u003e\n  \u003cli\u003eBlack oxide steel construction for corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003e4-48 thread size matches AGD Group 1 dial indicator standards\u003c\/li\u003e\n  \u003cli\u003eContact point length of 1\/2 inch (0.5 inches) for standard reach applications\u003c\/li\u003e\n  \u003cli\u003eTip diameter of 1\/64 inch for fine-tolerance measurement work\u003c\/li\u003e\n  \u003cli\u003eMeets AGD Group 1 industry designation for broad compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with dial indicators requiring AGD Group 1 contact points with a 4-48 thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the contact point into the dial indicator spindle. Use care when engaging the 4-48 thread to prevent cross-threading, which can damage the spindle or contact point. Ensure the dial indicator is removed from any active measurement setup before swapping contact points. No power lockout is required, but the indicator should be secured in a holder or fixture during installation to avoid dropping or damaging the instrument.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Black Oxide Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Designation\u003c\/strong\u003e: AGD Group 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Dial Indicators\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: 21-267-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696719102258,"sku":"21-267-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a41c5d0890ee4e0294a543f64d584d2.jpg?v=1788345562","url":"https:\/\/voomisupply.com\/products\/spi-21-267-0-tapered-contact-point-dial-indicator","provider":"Voomi Supply","version":"1.0","type":"link"}
