It expands to grip bore diameters ranging from 0.48 to 0.56 inches and delivers a holding force of 1,900 pounds when properly torqued. The clamp mounts to a fixture plate using three 6-32 mounting screws and is actuated by a 1\/4-20 center screw torqued to 13.3 ft\/lb. At 0.16 pounds, it is compact and suited for high-density fixture layouts. Machinists and tooling engineers install this type of clamp on CNC machining centers and manual setups where top-surface access to the workpiece must remain unobstructed.\u003c\/p\u003e\u003cp\u003eThe 31100 is intended for use in precision workholding applications where ID expansion clamping is preferred over traditional strap or toe clamps. It is well-suited for production machining environments requiring repeatable, low-profile fixturing. The flange diameter of 1.24 inches and overall height of 0.98 inches keep the clamp profile minimal. With three mount holes at a 0.91-inch mount hole diameter, it anchors securely to standard fixture plates or tombstones used in horizontal and vertical machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpansion diameter range of 0.48 to 0.56 inches for gripping bores in that range\u003c\/li\u003e\n\u003cli\u003e1,900 lb holding force for secure workpiece retention during machining\u003c\/li\u003e\n\u003cli\u003eActuated by a 1\/4-20 center screw with a specified torque of 13.3 ft\/lb\u003c\/li\u003e\n\u003cli\u003eThree-hole flange mount using 6-32 mounting screws for stable, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eLow-profile design at 0.98 inches overall height keeps the top surface accessible\u003c\/li\u003e\n\u003cli\u003eMild steel construction balances strength and machinability for general fixturing use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style workholding component compatible with standard fixture plates and tombstones that accept 6-32 mounting screws and have clearance for a 1.24-inch flange diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tooling engineers or machinists. Before installing or removing the clamp, ensure the machine is powered down and all motion axes are at a safe home position. Secure the flange to the fixture plate using three 6-32 mounting screws before actuating the center screw. Do not exceed the specified 13.3 ft\/lb torque on the center screw, as over-torquing can damage the expansion element or the workpiece bore.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Force\u003c\/strong\u003e: 1,900 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Expansion Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Expansion Diameter\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Screw Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Screw Thread Size\u003c\/strong\u003e: 6-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 1.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Hole Diameter\u003c\/strong\u003e: 0.91 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: 0.98 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Height\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Above Flange\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length Below Base\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 13.3 ft\/lb\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: 0.16 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: 31100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITEE-BITE","offers":[{"title":"Default Title","offer_id":51721506783538,"sku":"31100","price":54.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d66a70a35864fbe1a550c8c5243ad47b.jpg?v=1788578286","url":"https:\/\/voomisupply.com\/products\/mitee-bite-31100-id-expansion-clamp-mild-steel-1900-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
