It features a 0.5 inch ball diameter with a 0.25 inch threaded shank, providing a stable, accurate reference point on jigs, fixtures, and inspection setups. The shoulder design locks the ball at a consistent height, with a ball center to shoulder bottom distance of 0.3125 inches and a ball center to shank bottom distance of 0.625 inches. Heat-treated steel construction and a ball-and-shank concentricity of 0.0002 inches ensure repeatable accuracy under production conditions. This part is installed by machinists and quality technicians.\u003c\/p\u003e\u003cp\u003eThis tooling ball is suited for use in inspection fixtures, coordinate measuring machine (CMM) setups, and production jigs where a precise, repeatable datum point is required. The tapped shank threads directly into a prepared hole, and the shoulder seats flush against the workpiece or fixture surface to set ball height without additional adjustment. The 6-32 threaded hole in the shank adds mounting versatility for complex fixture configurations. Typical applications include aerospace, automotive, and general precision machining environments where tight tolerances are maintained throughout the inspection process.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShoulder design sets ball center height consistently at 0.3125 inches above the shoulder bottom\u003c\/li\u003e\n\u003cli\u003eHeat-treated steel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003eBall-and-shank concentricity of 0.0002 inches for high-accuracy reference applications\u003c\/li\u003e\n\u003cli\u003eTapped shank threads into fixture body for secure, repeatable installation\u003c\/li\u003e\n\u003cli\u003e6-32 tapped hole in shank allows additional fixturing or stacking configurations\u003c\/li\u003e\n\u003cli\u003eShoulder diameter of 0.49 inches provides a stable seating surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard inspection fixture and tooling ball applications requiring a 0.25 inch threaded shank with a 0.5 inch ball diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or quality technicians using standard hand tools to thread the shank into a pre-tapped fixture hole. Ensure the mating hole thread is clean and free of debris before installation to maintain seating accuracy. Do not overtighten, as this may distort the shoulder seating surface and affect ball center height. Verify concentricity and position after installation using appropriate gauging equipment before placing the fixture into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Center to Shoulder Bottom\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Center to Shank Bottom\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Attachment Type\u003c\/strong\u003e: Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Thread Size\u003c\/strong\u003e: 6-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall and Shank Concentricity\u003c\/strong\u003e: 0.0002 inches\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\u003eBreakaway\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 826875-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51692217139506,"sku":"826875-G","price":67.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7d173e687909bde7791ad0fe6b491e1.jpg?v=1788294707","url":"https:\/\/voomisupply.com\/products\/gibraltar-826875-g-shoulder-tooling-ball-inspection","provider":"Voomi Supply","version":"1.0","type":"link"}
