The clamp expands to engage bore diameters from 0.71 to 1.12 inches and delivers 4,000 pounds of holding force at a maximum torque of 49 ft\/lb. The body is constructed of steel for durability under the clamping loads typical in CNC and manual machining environments. Mounting is achieved with an 8-32 screw and a six-hole flange pattern. This part is installed by machinists, toolmakers, and fixturing specialists.\u003c\/p\u003e\u003cp\u003eThe 31210 is suited for workholding applications where external clamping is impractical or where bore-referenced location is required. The six-hole flange mount allows the clamp to be bolted directly into a fixture plate or tombstone. Typical applications include milling, grinding, and turning setups where part repeatability and concentricity are critical. The flange diameter of 1.968 inches and an overall height of 1.625 inches keep the clamp profile low relative to the workpiece, reducing interference with toolpaths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpansion diameter range: 0.71 to 1.12 inches for versatile bore engagement\u003c\/li\u003e\n\u003cli\u003e4,000 lb holding force at 49 ft\/lb torque for secure workholding\u003c\/li\u003e\n\u003cli\u003eSix-hole flange mount for rigid, repeatable fixture plate installation\u003c\/li\u003e\n\u003cli\u003eLow-profile design: 1.625 inches overall height with 1.968 inch flange diameter\u003c\/li\u003e\n\u003cli\u003eSteel construction for strength under high clamping loads\u003c\/li\u003e\n\u003cli\u003e8-32 mounting screw thread for standard tool compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in machining fixtures and workholding setups requiring ID bore engagement in the 0.71 to 1.12 inch diameter range. Consult fixture design requirements to confirm flange footprint and mount hole pattern compatibility before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or toolmaker during fixture build or changeover. Ensure the fixture plate or base is fully powered down or the machine is in a safe, locked-out state before mounting or adjusting the clamp. Use a calibrated torque wrench and do not exceed the rated 49 ft\/lb torque value stated by the manufacturer. Verify bore diameter is within the specified expansion range before applying clamping force to avoid damage to the clamp or workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Force\u003c\/strong\u003e: 4,000 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Diameter Range\u003c\/strong\u003e: 0.71 to 1.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 49 ft\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 1.968 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Hole Diameter\u003c\/strong\u003e: 1.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Mount Holes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Height\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Above Flange\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.625 inches\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 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: MITEE-BITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITEE-BITE","offers":[{"title":"Default Title","offer_id":51698927272242,"sku":"31210","price":124.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/deeeb24493c8cbd0ba7be93e96be3a51.jpg?v=1788369923","url":"https:\/\/voomisupply.com\/products\/mitee-bite-31210-id-expansion-clamp-steel-4000-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
