It expands from 1.15 inches to 3.06 inches in diameter and delivers up to 10,000 pounds of holding force when the 5\/8-11 center screw is torqued to 224 foot-pounds. The clamp features a 4.232-inch flange diameter with three mounting holes on a 3.646-inch bolt circle, using 1\/4-20 mounting screws for table or fixture attachment. Overall height is 1.79 inches. Machinists and fixture builders install this clamp when external clamping would obstruct toolpaths or when consistent bore-referenced positioning is required.\u003c\/p\u003e\u003cp\u003eThe 31400 is suited for use in machine shops, toolrooms, and production environments where repeatable inside-diameter workholding is needed. It is appropriate for chucking round or cylindrical parts that have a finished bore within the 1.15- to 3.06-inch expansion range. A locking ring is included to keep the expansion segments rigid and aligned during setup and loading. This clamp is typically mounted to a fixture plate or tombstone and is used in milling, turning, grinding, or inspection applications where bore-referenced clamping is the preferred method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpansion range of 1.15 inches to 3.06 inches accommodates a wide variety of bore sizes in a single clamp body\u003c\/li\u003e\n\u003cli\u003e10,000 pounds of holding force provides rigid, repeatable workholding for machining operations\u003c\/li\u003e\n\u003cli\u003eMild steel construction balances durability and machinability for general shop use\u003c\/li\u003e\n\u003cli\u003eLocking ring included to keep expansion segments rigid during workpiece loading\u003c\/li\u003e\n\u003cli\u003eThree-hole flange mount with 1\/4-20 screws and 3.646-inch bolt circle for straightforward fixture integration\u003c\/li\u003e\n\u003cli\u003e5\/8-11 center screw drives expansion with 224 foot-pounds of rated torque\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, tombstones, and subplates that accept a three-hole flange pattern on a 3.646-inch mount hole diameter with 1\/4-20 mounting screws.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or fixture engineer familiar with workholding principles. Ensure all mounting surfaces are clean and flat before securing the flange to the fixture plate. Torque the center screw to the rated value using a calibrated torque wrench — do not use impact tools on the center screw. Verify that the locking ring is properly seated before loading workpieces to prevent segment misalignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Expansion Diameter\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Expansion Diameter\u003c\/strong\u003e: 3.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Force\u003c\/strong\u003e: 10,000 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Screw Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Screw Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 4.232 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Hole Diameter\u003c\/strong\u003e: 3.646 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: 1.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Height\u003c\/strong\u003e: 1.27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Above Flange\u003c\/strong\u003e: 1.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length Below Base\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 224 foot-pounds\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: 4.03 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: MITEE-BITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITEE-BITE","offers":[{"title":"Default Title","offer_id":51698702352690,"sku":"31400","price":194.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/382b0d9192d0be4db1a57b262f2876cf.jpg?v=1788366665","url":"https:\/\/voomisupply.com\/products\/mitee-bite-31400-id-expansion-clamp-mild-steel-10000-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
