Machined from steel, it threads onto compatible dial indicator spindles using a 4-48 thread and provides a flat contact surface for accurate linear measurement. The contact point measures 9.53 mm in diameter and 2.58 mm (approximately 3\/32 inch) in length. This part is installed by metrology technicians, machine shop personnel, and quality control professionals who require consistent, repeatable surface contact during indicator setup and inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for use in dimensional inspection, fixture alignment, and surface measurement tasks in both shop floor and laboratory environments. It is a direct replacement or spare accessory for technicians maintaining dial indicator sets. The compact flat-tip geometry makes it appropriate for measurements on flat or broad workpiece surfaces where a pointed or spherical tip would be unsuitable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat contact point style for broad, flat surface measurement applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4-48 threaded shank for secure attachment to compatible indicator spindles\u003c\/li\u003e\n  \u003cli\u003e9.53 mm contact face diameter provides stable surface contact\u003c\/li\u003e\n  \u003cli\u003e2.58 mm contact point length (approximately 3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003eSold individually — package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 650 and 651 Back Plunger Dial Indicators and AGD Dial Indicators as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis contact point is installed and serviced by metrology or mechanical technicians familiar with dial indicator maintenance. Before replacing a contact point, ensure the indicator is removed from any active measurement fixture and the spindle is fully retracted. Use the correct thread engagement — avoid over-tightening, which can damage the 4-48 spindle threads. Verify indicator calibration after any contact point change per your facility or quality system procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Flat\u003c\/li\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: 9.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 2.58 mm (3\/32 inch)\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: 70805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540691386674,"sku":"70805","price":31.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f37ac6cc933502f2f30b961cf77d4db.jpg?v=1785862070","url":"https:\/\/voomisupply.com\/products\/starrett-70805-flat-contact-point-4-48-drop-indicator","provider":"Voomi Supply","version":"1.0","type":"link"}
