It features an articulated arm that allows multi-axis positioning and a fine adjustment mechanism for precise gauge placement. The rectangular magnetic base delivers 70 pounds of pull force, holding the assembly firmly to ferrous surfaces such as machine tables, surface plates, lathe beds, and milling fixtures. The unit ships complete with the base included. Machinists, toolroom technicians, and quality control inspectors install and use this type of holder in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThe 68621 is suited for use in machine shops, toolrooms, and quality control stations where a dial indicator or test indicator must be held in a fixed position relative to a workpiece. The articulated arm provides the reach and angular flexibility needed to position a gauge on irregular or hard-to-access surfaces. The adjustable rectangular base can be placed on any clean, flat ferrous surface. Fine adjustment allows repeatable, controlled repositioning without disturbing the magnetic hold.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e70 lb magnetic pull force holds securely to ferrous machine surfaces\u003c\/li\u003e\n  \u003cli\u003eArticulated arm design allows multi-axis positioning flexibility\u003c\/li\u003e\n  \u003cli\u003eFine adjustment mechanism enables precise indicator placement\u003c\/li\u003e\n  \u003cli\u003eRectangular adjustable base included with unit\u003c\/li\u003e\n  \u003cli\u003eOverall length of 8.5 inches provides adequate reach for most setups\u003c\/li\u003e\n  \u003cli\u003eCompact base footprint fits standard machine table and surface plate applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style accessory compatible with standard dial indicators and test indicators that use conventional stem or post mounting, as used across general machining and inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnsure the mounting surface is clean and free of chips, oil film, or debris before engaging the magnetic base, as contamination reduces effective holding force. Engage the magnetic lock fully before applying load to the arm or adjusting the indicator. Technicians should verify that the base pull force is adequate for the expected vibration and cutting forces present in the work environment. Do not mount on non-ferrous surfaces such as aluminum or granite without an appropriate adapter or clamping fixture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic Pull Force\u003c\/strong\u003e: 70 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Articulated Arm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Mount Type\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Type\u003c\/strong\u003e: Adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Base\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 68621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541366931762,"sku":"68621","price":213.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbe7ad49038062a8acbd4c8506bd1607.jpg?v=1785873703","url":"https:\/\/voomisupply.com\/products\/starrett-68621-indicator-positioner-holder-magnetic-base","provider":"Voomi Supply","version":"1.0","type":"link"}
