Machined from black oxide steel, this contact point threads in at a 4-48 thread size and measures 1 inch in contact point length with a measurement tip diameter of 0.06 inches. It conforms to AGD Group 1 industry standards, making it a drop-in fit for a wide range of standard dial indicator bodies. Metrology technicians, machinists, and quality control professionals install this type of contact point when flat-surface probing or fine-point measurement is required.\u003c\/p\u003e\u003cp\u003eThis contact point is suited for bench inspection, surface plate work, and machine setup tasks where a needle-style tip provides better access to fine features or narrow surfaces. The flat needle profile reduces contact area at the measurement tip, improving accuracy on soft or delicate workpiece surfaces. It is packaged individually and is appropriate for both production floor and toolroom environments where AGD Group 1 dial indicators are in regular use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat needle contact point style for precision probing on fine or narrow surfaces\u003c\/li\u003e\n\u003cli\u003eBlack oxide steel construction for wear resistance and corrosion inhibition\u003c\/li\u003e\n\u003cli\u003e4-48 thread size for compatibility with AGD Group 1 dial indicators\u003c\/li\u003e\n\u003cli\u003e1 inch contact point length for extended reach in confined measurement locations\u003c\/li\u003e\n\u003cli\u003e0.06 inch tip diameter for small-area contact measurement\u003c\/li\u003e\n\u003cli\u003eMeets AGD Group 1 industry designation standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with AGD Group 1 dial indicators accepting a 4-48 threaded contact point.

Ensure the dial indicator spindle is fully retracted and the indicator is removed from any active fixture before swapping contact points. Use the appropriate spanner wrench or contact point tool to thread the 4-48 contact point in by hand and snug gently — do not overtighten, as the fine thread can be damaged. Verify indicator calibration after any contact point change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Flat Needle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Black Oxide Steel\u003c\/li\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Designation\u003c\/strong\u003e: AGD Group 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Dial Indicators\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-265-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710964728114,"sku":"21-265-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adfbd8936e35e293556fe382202f4e69.jpg?v=1788472937","url":"https:\/\/voomisupply.com\/products\/spi-21-265-4-flat-needle-contact-point-dial-indicator","provider":"Voomi Supply","version":"1.0","type":"link"}
