Mitee-bite 31730 Id Expansion Clamp 500 Lb Stainless Steel

Product Description

The MITEE-BITE 31730 is a stainless steel internal-diameter (ID) expansion clamp designed for precision bore and bushing installation applications. It expands radially outward to grip the inner wall of a bore or bushing, delivering 500 pounds of holding force from a compact, single-mount-hole flange body. The overall height is 0.5 inches and the flange diameter is 0.25 inches. The 5-40 mounting screw thread makes installation straightforward in tight, precision machined setups. Licensed machinists, toolmakers, and fixture builders typically specify this clamp where positive, repeatable workholding inside a bore is required.

The 31730 is suited for use in precision machining fixtures, CNC workholding setups, and tooling plates where a low-profile, high-force clamp must seat inside a drilled or reamed hole. The expansion range spans 0.25 inches minimum to a 0.015-inch maximum expansion diameter, making it appropriate for close-tolerance bore applications. The stainless steel construction resists corrosion in coolant-rich machining environments. This clamp is sold individually and is a direct fit wherever a small-diameter ID expansion clamp with a 5-40 drive screw is specified.

Key Features

• 500 pounds holding force from a compact 0.25-inch flange diameter body
• Stainless steel construction for corrosion resistance in coolant environments
• 5-40 mounting screw thread for precise torque control during installation
• 0.27-inch height above flange keeps the profile low in tight fixture setups
• Single mount hole design simplifies integration into precision bore locations
• Designed specifically for precision bore and bushing installation applications

Compatibility

Designed for use in precision bore and bushing installation applications requiring a small-diameter ID expansion clamp with a 5-40 mounting screw and a 0.25-inch mount hole diameter.

Installation Notes

Installation is performed by qualified machinists or toolmakers working with precision workholding fixtures. Power down and de-energize any CNC or automated equipment before seating or adjusting the clamp. Use the correct driver for the 5-40 screw and do not exceed the rated holding force to avoid bore damage. Verify bore diameter and surface finish meet the clamp manufacturer specifications before installation.
