The expansion diameter range spans 0.9 to 1.39 inches, making it suitable for a variety of bore sizes within that window. A 1\/2-13 center screw drives the expansion mechanism, while three 8-32 mounting screws secure the clamp body to a fixture plate or tombstone. Machinists and fixture builders install this clamp where external clamping is impractical or where full top-surface access to the workpiece is required.\u003c\/p\u003e\n\u003cp\u003eThis clamp is intended for workholding applications in CNC machining, milling, and fixturing environments where a clean, unobstructed work surface is essential. The three-point mounting pattern distributes clamping loads evenly across the flange, and an optional recessed dowel pin can be installed into the flange for additional rigidity and repeatability during high-volume production runs. It is well suited to fixture plates, tooling plates, and custom jig assemblies in job shop and production machining settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExpansion diameter range of 0.9 to 1.39 inches accommodates a range of bore sizes in a single clamp body\u003c\/li\u003e\n  \u003cli\u003e5,900 pounds of holding force provides secure grip for demanding milling and machining operations\u003c\/li\u003e\n  \u003cli\u003eMild steel construction balances strength and machinability for general-purpose fixturing\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 center screw thread for straightforward torque application with standard tooling\u003c\/li\u003e\n  \u003cli\u003eThree-hole flange mounting pattern with 8-32 mounting screws for stable, low-profile installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with optional recessed dowel pin installation for improved repeatability and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style workholding component for use with fixture plates, tooling plates, and custom jig assemblies where the bore diameter falls within the 0.9 to 1.39 inch expansion range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified fixture builders or machinists. Power down and de-energize any associated machine tool before installing or adjusting the clamp. Secure the three 8-32 mounting screws evenly before applying final torque to the 1\/2-13 center screw. For additional positional repeatability, install a recessed dowel pin into the flange as noted in the product specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Force\u003c\/strong\u003e: 5,900 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Expansion Diameter\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Expansion Diameter\u003c\/strong\u003e: 1.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Screw Thread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Screw Thread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 120 foot-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 2.205 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Hole Diameter\u003c\/strong\u003e: 1.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Mount Holes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Above Flange\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExpansion Height\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length Below Base\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Mild Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.47 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: MITEE-BITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITEE-BITE","offers":[{"title":"Default Title","offer_id":51698873696562,"sku":"31250","price":87.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8daba0a0f608a356da8fedd33fbaca7.jpg?v=1788369215","url":"https:\/\/voomisupply.com\/products\/mitee-bite-31250-id-expansion-clamp-mild-steel-5900-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
