Mitee-bite 31760 Id Expansion Clamp 2500 Lb Stainless Steel

Product Description

The MITEE-BITE 31760 is a stainless steel internal diameter (ID) expansion clamp designed to secure workpieces from the inside of a bore or hole during machining, fixturing, or assembly operations. It delivers 2,500 pounds of holding force and expands within a diameter range of 0.625 inches minimum to accommodate bore clamping applications. The 5/16-18 mounting screw threads into the clamp body to drive radial expansion, locking the clamp firmly against the bore wall. Machinists, toolmakers, and fixture builders working with CNC or manual setups install this clamp where external fixturing is not practical or where inside-diameter clamping is required for consistent part location.

The 31760 is suited for precision fixturing applications in machine shops, manufacturing cells, and production environments. It fits bores with a mount hole diameter of 0.625 inches and uses a single mount hole configuration. The compact overall height of 0.75 inches and flange diameter of 0.625 inches allow installation in tight bore geometries. It is appropriate for use in both prototype and production fixture plates where repeatable, high-force ID clamping is needed.

Key Features

• 2,500 lb holding force for secure workpiece retention during machining operations
• Stainless steel construction for corrosion resistance and durability in coolant environments
• 5/16-18 mounting screw for straightforward actuation with standard tooling
• 0.625 inch mount hole diameter with single mount hole configuration
• Compact 0.75 inch overall height suits shallow bore and low-profile fixture applications
• Thread length below base of 0.52 inches accommodates standard fixture plate depths

Compatibility

Designed as an OEM-style replacement and direct-fit ID expansion clamp for fixture plates and workholding setups requiring a 0.625 inch mount hole diameter with a 5/16-18 mounting screw thread.

Installation Notes

Installation is typically performed by a machinist or toolmaker using standard hand tools sized for the 5/16-18 mounting screw. Before installing or adjusting the clamp, ensure all associated machine power is off and the fixture plate is secured and free from the machine spindle. Do not exceed the rated holding force by over-torquing the mounting screw, as this can damage the bore or the clamp body. Verify bore diameter tolerance is within the clamp expansion range before final assembly.
