The unit features a fine adjustment mechanism that allows controlled, incremental repositioning of the indicator without disturbing the overall setup. The magnetic base mount style enables quick attachment and release on ferrous machine surfaces. A universal indicator holder is included. The arm measures 8 inches in length, making it suitable for reaching workpieces in confined fixture setups. Machinists, toolmakers, and quality control technicians install and use this tool as a standard part of workholding and inspection workflows.\u003c\/p\u003e\n\u003cp\u003eThis holder is used in applications where repeatable indicator placement is required, such as runout checks, surface parallelism measurement, bore alignment, and machine axis verification. The articulated arm design allows the indicator to be positioned at multiple angles and orientations without requiring separate adapters. The fine adjustment feature is particularly useful when zeroing an indicator on a reference surface or when incrementally repositioning between measurement points on a part. It is suited for use on milling machines, surface plates, lathes, and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eArticulated arm design allows multi-angle indicator positioning without additional adapters\u003c\/li\u003e\n  \u003cli\u003eFine adjustment mechanism provides controlled, incremental movement for precise indicator placement\u003c\/li\u003e\n  \u003cli\u003eMagnetic base mount style for fast attachment and removal on ferrous machine surfaces\u003c\/li\u003e\n  \u003cli\u003eUniversal indicator holder included, compatible with standard dial and test indicators\u003c\/li\u003e\n  \u003cli\u003e8-inch arm length provides reach into confined workholding and fixture setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard indicator positioner holder for use with dial indicators and test indicators in typical machine shop and inspection applications.

Before mounting, ensure the ferrous surface is clean and free of chips or oil film that would reduce magnetic holding force. Position the arm and lock all articulating joints before taking measurements to prevent indicator drift. Verify indicator contact force and preload per the indicator manufacturer's specification before recording measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eFine Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Universal Indicator Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Base\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 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: 64438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541741797682,"sku":"64438","price":262.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/197b34602f911bba56b8139a98b88742.jpg?v=1785883649","url":"https:\/\/voomisupply.com\/products\/starrett-64438-indicator-positioner-holder-fine-adjustment","provider":"Voomi Supply","version":"1.0","type":"link"}
