Machined from steel, this contact point features a 4-48 thread size and a contact point length of 9.53 mm. The overall length measures 0.25 inches (6.30 mm), with a body diameter of 9.42 mm (3\/8 inch fraction). It is a direct-fit replacement-style accessory installed by machinists, metrology technicians, and calibration professionals working with standard AGD-style dial indicators on the shop floor or in the inspection room.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for dimensional inspection work in manufacturing, toolroom, and quality control environments. It threads directly onto AGD dial indicators and is appropriate for applications requiring repeatable surface contact with workpieces during runout, flatness, or positional measurements. The steel construction provides durability across repeated use cycles on metal surfaces. It ships as a single unit and is compatible with indicators that accept the standard 4-48 threaded contact point interface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel contact point material for durability in industrial measurement environments\u003c\/li\u003e\n  \u003cli\u003e4-48 thread size fits standard AGD dial indicator stems\u003c\/li\u003e\n  \u003cli\u003eContact point length of 9.53 mm for consistent surface engagement\u003c\/li\u003e\n  \u003cli\u003eBody diameter of 9.42 mm (3\/8 inch) for stable seating\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.25 inches (6.30 mm) for compact fitment\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suits individual replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with AGD dial indicators that accept a 4-48 threaded contact point, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by metrology technicians or machinists familiar with dial indicator maintenance. Before replacing the contact point, remove the indicator from the measuring fixture and ensure it is not under spring load. Thread the contact point in by hand to avoid cross-threading the 4-48 stem, then snug with the appropriate small wrench. Do not overtighten, as this can damage the indicator stem threads.\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\u003eContact Point Length\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 9.42 mm (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.25 inches (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\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: 70790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544098603314,"sku":"70790","price":33.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41b68507dc34f52ac6b98c078f4598fe.jpg?v=1785924127","url":"https:\/\/voomisupply.com\/products\/starrett-70790-drop-indicator-contact-point-4-48-agd","provider":"Voomi Supply","version":"1.0","type":"link"}
