Gibraltar 22720.0124 Headless Rolling Ball Clamping Screw M12

Product Description

The GIBRALTAR 22720.0124 is a headless rolling ball end clamping screw designed for precision workholding and fixturing applications. The rolling ball end allows the screw to make secure, angled contact with a workpiece without marring the surface, distributing clamping force evenly. Manufactured from steel throughout, including the 8.5mm ball, this screw carries a maximum load capacity of 6,744 pounds. The M12 thread and 6mm hex key drive make it compatible with standard fixturing components. It is commonly installed by machinists, toolmakers, and fixture builders in industrial and manufacturing environments.

This clamping screw is suited for use in jig and fixture assemblies, clamp bodies, and modular workholding systems where a headless profile is required to keep the fastener flush or below the mounting surface. The 32mm overall length fits compact fixture blocks and standard clamp bodies. Applications include milling, grinding, and general machining setups where repeatable, controlled clamping force is critical.

Key Features

• Headless design keeps the screw profile flush or recessed within the clamping body
• Rolling ball end allows angular contact and reduces workpiece marring
• Steel screw and steel ball construction for durability under high clamping loads
• 6,744 pound maximum load capacity for demanding fixturing applications
• M12 thread size with 6mm hex key drive for precise torque application
• 32mm overall length suits compact and standard fixture block configurations

Compatibility

Designed as a standard-style replacement or direct-fit component for M12-threaded clamp bodies, jig fixtures, and modular workholding systems requiring a headless rolling ball end clamping screw.

Installation Notes

Installation is performed by machinists or fixture technicians using a 6mm hex key. Ensure the mating clamp body or fixture block is free of debris and that threads are clean before installation. Do not exceed the rated maximum load capacity of 6,744 pounds. De-energize or secure any powered equipment before adjusting or replacing clamping components in an active fixture setup.
