It features a 4-48 thread size, a diameter of 13\/64 inches (5.16 mm), and a contact point length of 5\/32 inches (3.97 mm). The overall length is 1\/4 inch (6.30 mm). This contact point is a special form style, intended for precise measurement applications where accurate surface contact is critical. It is installed and used by machinists, tool and die technicians, quality control inspectors, and calibration professionals working with AGD-style dial indicators on inspection setups, fixtures, and surface plates.\u003c\/p\u003e\n\u003cp\u003eThis contact point fits AGD dial indicators and is suited for dimensional inspection work in machine shops, manufacturing facilities, and metrology labs. Its compact overall length makes it appropriate for close-tolerance measurements in tight spaces. The steel construction provides durability for repeated contact cycles in shop environments. It is packaged and sold individually, making it a straightforward replacement for worn or damaged contact points on existing AGD dial indicators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-48 thread size for direct installation into AGD dial indicator stems\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and consistent contact geometry\u003c\/li\u003e\n  \u003cli\u003e13\/64 inches (5.16 mm) diameter contact face\u003c\/li\u003e\n  \u003cli\u003e5\/32 inches (3.97 mm) contact point length\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch overall length for compact fitment in tight measurement setups\u003c\/li\u003e\n  \u003cli\u003eSpecial form dial indicator style for precise surface contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with AGD dial indicators requiring a 4-48 threaded contact point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or metrology technicians using the appropriate thread engagement for 4-48 fasteners. Remove the existing contact point before installation and ensure the indicator stem threads are clean and undamaged. Do not overtighten the contact point, as this can damage the fine 4-48 threads on the indicator stem. Verify indicator calibration and zeroing after replacing the contact point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 13\/64 inches (5.16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 5\/32 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/4 inch (6.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: AGD Dial Indicators\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Special Form Dial Indicator\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539083952434,"sku":"70797","price":18.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28ec9a0482e01bb343aea311960bfe51.jpg?v=1785834591","url":"https:\/\/voomisupply.com\/products\/starrett-70797-drop-indicator-contact-point-4-48-agd","provider":"Voomi Supply","version":"1.0","type":"link"}
