It threads in on a 4-48 thread and seats a 3\/8-inch diameter ball at the tip. The contact point length measures 3\/32 inches, with an overall length of 1\/4 inch. This type of contact point is used when a spherical tip is needed to accurately transfer displacement readings on curved, irregular, or precision-machined surfaces. Installation is straightforward and requires only a compatible AGD-style indicator body. Metrology technicians, machinists, and quality control personnel are the primary users of this component.\u003c\/p\u003e\n\u003cp\u003eThis contact point fits standard AGD dial indicators that accept 4-48 threaded contact points. It is well suited for inspection setups on machine tools, surface plates, and fixture gauging applications in both shop-floor and lab environments. The steel ball construction handles repeated contact cycles on metal workpieces without significant deformation, maintaining measurement integrity across a production run or inspection series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-48 thread size for compatibility with AGD dial indicator spindles\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch diameter steel ball tip for contact on curved or irregular surfaces\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch contact point length keeps the ball close to the spindle for stable readings\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch overall length for compact installation in tight gauging setups\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability through repeated measurement cycles\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.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the contact point into the spindle of the dial indicator by hand, then snugging it with the appropriate wrench if needed — do not overtighten, as the small 4-48 thread is fine-pitched and easily damaged. Remove the indicator from any active gauging fixture before swapping contact points. Verify that the replacement contact point is fully seated and the indicator reads zero correctly against a known reference before returning the instrument to service.\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 Style\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 3\/32 inches (2.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/4 inches (6.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 70793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541979431218,"sku":"70793","price":22.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/520537deb9b086f9d98fd32525ee3dae.jpg?v=1785888762","url":"https:\/\/voomisupply.com\/products\/starrett-70793-ball-contact-point-agd-dial-indicators","provider":"Voomi Supply","version":"1.0","type":"link"}
