Threaded to the AGD Group 1 industry standard with a 4-48 thread size, it attaches securely to compatible indicator stems. The contact point measures 1 inch in length with a 0.06-inch tip diameter, providing accurate surface contact during inspection tasks. Manufactured from black oxide steel, it offers corrosion resistance and durability under regular shop use. This type of contact point is commonly installed by machinists, quality control technicians, and tool and die professionals who require consistent, repeatable measurement contact geometry.\u003c\/p\u003e\u003cp\u003eThis contact point is suited for use in machine shops, inspection rooms, and manufacturing environments where dial indicators are used to measure surface deviation, runout, concentricity, or part alignment. The offset flat needle profile allows access to recessed surfaces or features that a standard straight contact point cannot reach. It is a direct-mount accessory compatible with AGD Group 1 dial indicators accepting a 4-48 threaded contact point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOffset flat needle profile for access to recessed or hard-to-reach measurement surfaces\u003c\/li\u003e\n\u003cli\u003e4-48 thread size matches AGD Group 1 dial indicator stems\u003c\/li\u003e\n\u003cli\u003e1 inch contact point length for extended reach applications\u003c\/li\u003e\n\u003cli\u003e0.06 inch tip diameter for precise surface contact\u003c\/li\u003e\n\u003cli\u003eBlack oxide steel construction for corrosion resistance and shop durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with dial indicators accepting a 4-48 threaded contact point in the AGD Group 1 industry designation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand-threading the contact point into the indicator stem — no special tools are required, but avoid overtightening to prevent thread damage on the indicator body. Ensure the dial indicator is removed from the measuring setup and at rest before changing contact points. Verify thread engagement is complete and the contact point seats flush before returning the indicator to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Offset Flat Needle\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\u003ePoint Material\u003c\/strong\u003e: Black Oxide Steel\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\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: 21-266-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716066214194,"sku":"21-266-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e49f0f45efc306e0d009205dcb123a80.jpg?v=1788521867","url":"https:\/\/voomisupply.com\/products\/spi-21-266-2-offset-flat-needle-contact-point-dial-indicator","provider":"Voomi Supply","version":"1.0","type":"link"}
