Gibraltar 22720.0056 Headless Rolling Ball Clamping Screw M5

Product Description

The GIBRALTAR 22720.0056 is a headless rolling ball end clamping screw designed for precise workholding and fixturing applications in machine tool and industrial settings. Threaded M5 with a 20mm overall length, this screw uses a 3mm rolling steel ball tip to apply clamping force with reduced surface marring compared to standard point-set screws. The 2.5mm hex key drive allows for controlled torquing in tight fixture locations. Rated for a maximum load capacity of 1,011 pounds, it is built for demanding clamping scenarios where consistent holding force is critical. Machining professionals, toolmakers, and fixture builders are the primary installers of this fastener.

This clamping screw is suited for use in drill jigs, milling fixtures, vise jaws, and modular workholding systems where a rolling ball contact point is preferred over a flat or cone tip. Its steel construction on both the screw body and ball provides durability across repeated use cycles. The headless profile allows the screw to sit flush or below the fixture surface, keeping the work envelope clear of obstructions during machining operations.

Key Features

• Headless design allows flush or sub-flush installation in fixture bodies
• Rolling steel ball tip reduces workpiece surface damage during clamping
• M5 thread size for compatibility with standard metric fixture components
• 20mm overall length suits shallow to moderate fixture wall thicknesses
• 1,011 lb maximum load capacity for secure holding under machining forces
• 2.5mm hex key drive for precise torque application in confined spaces

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for metric M5 threaded workholding fixtures, jigs, and modular clamping systems requiring a rolling ball end clamping screw.

Installation Notes

Installation is typically performed by toolmakers or fixture technicians using a 2.5mm hex key. Ensure the threaded bore is clean and free of chips or debris before threading the screw in. Do not exceed the rated maximum load capacity of 1,011 pounds to avoid deformation of the rolling ball or thread damage. Confirm thread engagement depth is sufficient for the applied load before putting the fixture into service.
