{"product_id":"starrett-64632-drop-indicator-contact-point-extension","title":"Starrett 64632 Drop Indicator Contact Point Extension","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe STARRETT 64632 is a contact point extension designed for drop-style dial indicators. It threads directly onto the indicator spindle using a 4-48 thread and extends the reach of the contact point by 0.5 inches. Constructed from steel, it provides the rigidity and durability required for repeatable measurement in shop or field use. This type of extension is a standard accessory for AGD dial indicators and is used when the base contact point cannot reach the measurement surface directly. Licensed metrology technicians, machinists, and quality control inspectors install and swap these extensions as part of routine indicator setups.\u003c\/p\u003e\n\u003cp\u003eThis extension is suited for use in manufacturing, machine shop, and inspection environments where AGD-style dial indicators are employed. Typical applications include checking runout, surface variation, and part geometry on lathes, milling machines, surface plates, and inspection fixtures. The 4-48 thread is the AGD standard for contact points and extensions, making this a commonly stocked replacement and supplemental accessory for indicator kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel construction for rigidity and long service life\u003c\/li\u003e\n  \u003cli\u003e4-48 thread matches AGD dial indicator contact point standard\u003c\/li\u003e\n  \u003cli\u003e0.5 inch extension length increases contact point reach\u003c\/li\u003e\n  \u003cli\u003eDrop indicator style for use in vertical spindle applications\u003c\/li\u003e\n  \u003cli\u003eSingle-piece replacement accessory, sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with AGD dial indicators that accept 4-48 threaded contact point accessories.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread the extension onto the indicator spindle by hand, taking care not to cross-thread the 4-48 connection. Use a proper contact point wrench if needed to snug the extension without over-torquing the threaded joint. Remove the indicator from its holder before swapping contact point extensions to avoid stressing the spindle. Verify indicator calibration and zero after any contact point change.\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\u003eExtension Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: AGD Dial Indicators\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: 64632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542444015922,"sku":"64632","price":35.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e2f3b36b29a0e36e80d522dc2013e0e.jpg?v=1785900710","url":"https:\/\/voomisupply.com\/products\/starrett-64632-drop-indicator-contact-point-extension","provider":"Voomi Supply","version":"1.0","type":"link"}
