Gibraltar 22720.0122 Headless Rolling Ball End Clamping Screw

Product Description

The GIBRALTAR 22720.0122 is a headless rolling ball end clamping screw designed for precision fixturing and workholding applications. It features an M12 thread size and an overall length of 22 millimeters, with an 8.5-millimeter rolling ball tip that allows for self-aligning contact against workpieces. The rolling ball design reduces marring on finished surfaces and distributes clamping force evenly. Both the screw body and ball are constructed from steel, providing durability under the rated maximum load capacity of 6,744 pounds. A 6-millimeter hex key drive allows for controlled, repeatable tightening. This fastener is installed by machinists, toolmakers, and fixture builders in precision manufacturing environments.

This clamping screw is suited for use in modular fixturing systems, tooling plates, and machine vises where secure, adjustable workholding is required. Its headless profile keeps the fastener flush or recessed within the fixture body, reducing interference with workpiece positioning or adjacent tooling. The rolling ball tip accommodates slight angular misalignment between the screw axis and the clamped surface, making it a practical choice for angled or contoured workpieces in both job shop and production settings.

Key Features

• Headless design sits flush or recessed in fixture bodies to minimize interference
• Rolling ball tip self-aligns to workpiece surfaces and reduces marring
• M12 thread size with 22-millimeter overall length for compact fixturing
• 6,744-pound maximum load capacity for heavy-duty clamping
• 8.5-millimeter ball diameter provides broad contact point distribution
• 6-millimeter hex key drive for precise torque application

Compatibility

Designed as a standard M12 headless rolling ball end clamping screw for use in modular fixturing systems, tooling plates, and workholding assemblies that accept M12-threaded clamping components.

Installation Notes

Installation is typically performed by machinists or toolmakers using a 6-millimeter hex key. Ensure the receiving threaded hole is clean and free of debris before installation. Do not exceed the rated maximum load capacity of 6,744 pounds. Inspect the rolling ball for free rotation and smooth seating against the workpiece surface before applying final clamping force.
