The ball measures 12 mm in diameter with a 6 mm threaded shank, a ball center to shank bottom distance of 22 mm, and a ball center to shoulder bottom distance of 12 mm. The shoulder diameter is 12.50 mm. Constructed from heat-treated steel, this tooling ball provides consistent, repeatable positioning accuracy. Ball and shank concentricity is held to 0.0002 inch, making it suitable for applications where tight positional tolerances are required. It is installed by machinists, tool and die makers, and quality technicians.\u003c\/p\u003e\u003cp\u003eThis tooling ball is used in fixture building, coordinate measuring machine (CMM) setups, and general inspection workflows where a reliable, fixed reference point is needed. The threaded shank attachment allows secure installation into tapped fixtures or inspection plates. The shoulder design provides a positive stop for consistent seating depth, reducing setup variation between measurements or fixture assemblies. It is well suited to production environments where tooling balls are installed and removed repeatedly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 mm precision steel ball for inspection and fixture reference applications\u003c\/li\u003e\n\u003cli\u003eHeat-treated steel construction for hardness and dimensional stability\u003c\/li\u003e\n\u003cli\u003eThreaded shank attachment type for secure, repeatable installation\u003c\/li\u003e\n\u003cli\u003eShoulder design provides a positive stop at 12 mm ball center to shoulder bottom\u003c\/li\u003e\n\u003cli\u003eBall and shank concentricity of 0.0002 inch for high-accuracy positioning\u003c\/li\u003e\n\u003cli\u003eNo breakaway feature — fixed ball configuration for stable reference use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shoulder tooling ball for use in threaded fixture plates, CMM setups, and inspection tooling systems that accept a 6 mm threaded shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or quality technicians using standard hand tools appropriate for the shank thread size. Ensure the mating fixture or plate is tapped to the correct thread specification before installation. Seat the shank fully until the shoulder contacts the mounting surface to achieve the designed ball center height. Avoid over-torquing the shank, as this can stress the ball-to-shank joint and affect concentricity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooling Ball Style\u003c\/strong\u003e: Inspection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 12.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Center to Shank Bottom\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Center to Shoulder Bottom\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Attachment Type\u003c\/strong\u003e: Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall and Shank Concentricity\u003c\/strong\u003e: 0.0002 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-Treated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreakaway\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapped Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 826887-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693047873842,"sku":"826887-G","price":76.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49e3846d2e69e64ce014e1a0ca63afad.jpg?v=1788306657","url":"https:\/\/voomisupply.com\/products\/gibraltar-826887-g-shoulder-tooling-ball-12-mm-inspection","provider":"Voomi Supply","version":"1.0","type":"link"}
