This special form contact point features a 4-48 threaded stem for secure attachment to compatible indicator spindles. Hardened steel construction provides resistance to wear and deformation during repeated measurement cycles, making it suitable for high-use environments in machine shops, fabrication facilities, and field inspection work. Metrology technicians and precision measurement professionals install this contact point as a replacement or alternate-form tip on AGD-standard dial indicators.\u003c\/p\u003e\n\u003cp\u003eThis contact point is used in dimensional inspection and quality control applications where a specific contact geometry is required. The special form profile suits situations where a standard ball-end tip is not appropriate for the surface being measured. Typical applications include inspection of machined parts, surface profiling, and setup work on mills, lathes, and grinding machines. The 4-48 thread is the AGD standard for dial indicator contact points, making this a straightforward drop-in replacement in most setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel construction for extended wear life under repeated contact\u003c\/li\u003e\n  \u003cli\u003e4-48 threaded stem conforming to AGD standard for dial indicators\u003c\/li\u003e\n  \u003cli\u003eSpecial form contact geometry for applications requiring a non-standard tip profile\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.11 pounds, minimizing added mass on the indicator spindle\u003c\/li\u003e\n  \u003cli\u003eDirect replacement contact point for AGD-style dial indicators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement contact point for AGD-standard dial indicators accepting a 4-48 threaded stem.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact points are installed and removed by hand or with a light wrench on the 4-48 threaded stem. Ensure the indicator spindle threads are clean and free of debris before installation. Do not overtighten the contact point, as this can damage the spindle threads or affect indicator calibration. After installation, verify indicator zero and repeatability 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\u003eMaterial\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Type\u003c\/strong\u003e: Special Form\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: AGD (American Gage Design)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 70801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51525477630258,"sku":"70801","price":20.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e558bf844320f44fec7ad8d1385c2e2.jpg?v=1785474986","url":"https:\/\/voomisupply.com\/products\/starrett-70801-agd-indicator-contact-point-4-48-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
