Mitee-bite 38730 Id Expansion Clamp 500 Lb Stainless Steel

Product Description

The MITEE-BITE 38730 is a stainless steel internal diameter (ID) expansion clamp designed to grip bores and bushings from the inside with high holding force. It expands within a bore ranging from 0.2362 inches minimum to a maximum expansion range of 0.015 inches above that diameter, generating up to 500 pounds of holding force. The clamp is actuated by an M3 x 0.50 center screw and mounts through a single 0.25-inch mounting hole. It is used in precision fixturing, workholding, and bushing installation applications where external clamping is not practical. Machinists and toolroom technicians are the primary installers of this component.

The 38730 is suited for precision bore workholding and bushing installation setups in machine shop and manufacturing environments. Its compact stainless steel construction makes it appropriate for applications where corrosion resistance and dimensional stability are required. The single-mount-hole flange design allows integration into custom fixture plates or tooling bodies. It is well matched to applications requiring repeatable, low-profile internal clamping where the bore access point serves as the primary datum.

Key Features

• Stainless steel construction for corrosion resistance and durability
• M3 x 0.50 center screw actuation for precise engagement control
• Minimum expansion diameter of 0.2362 inches with 0.015-inch expansion range
• Single 0.25-inch mount hole for straightforward fixture integration
• Designed for precision bore and bushing installation applications

Compatibility

Designed as an OEM-style replacement or new-installation component for precision fixturing and workholding systems requiring internal bore expansion clamping with a minimum bore diameter of 0.2362 inches.

Installation Notes

Installation is typically performed by a machinist or tooling technician using standard M3 hex drive tooling to actuate the center screw. Ensure the bore surface is clean and free of burrs or debris before inserting the clamp to achieve full rated holding force. Do not exceed the specified expansion diameter range, as over-driving the center screw can damage the clamp body or the workpiece bore. Follow applicable workholding safety practices and verify holding force is sufficient for the intended cutting or assembly loads before operation.
