Gibraltar 22720.0558 Headless Ball End Clamping Screw M5

Product Description

The GIBRALTAR 22720.0558 is a headless, plain flat face ball end clamping screw designed for precision workholding and fixturing applications. Manufactured from steel, this M5-threaded screw features a 3mm ball diameter and an overall length of 24.5mm. It is driven with a 2.5mm hex key and is rated for a maximum load capacity of 1,011 pounds. This type of clamping screw is a standard component in machine shop tooling setups, used to apply controlled clamping force without marring workpiece surfaces through the flat face ball contact design.

Ball end clamping screws like the 22720.0558 are commonly installed in modular fixturing systems, vise jaws, tooling plates, and custom workholding assemblies found in production machining and fabrication environments. The headless design allows the screw to sit flush or below the surface of the clamping body, making it suitable for low-profile fixture configurations. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Key Features

• Headless design with plain flat face ball end for flush installation and non-marring clamping contact
• M5 thread size for compatibility with standard metric fixturing components
• Steel construction on both screw body and ball for durability under load
• 1,011-pound maximum load capacity suitable for production workholding demands
• 2.5mm hex key drive for precise torque application in tight fixture layouts
• 24.5mm overall length provides sufficient thread engagement in standard clamping bodies

Compatibility

Designed as a standard metric M5 headless ball end clamping screw for use in modular fixturing systems, tooling plates, and workholding assemblies that accept M5 threaded clamping screws.

Installation Notes

Installation is typically performed by machinists or fixture builders using a 2.5mm hex key. Ensure the receiving threaded hole is clean and free of debris before installation to avoid cross-threading. Do not exceed the rated load capacity of 1,011 pounds during clamping operations. Confirm the mating fixture or clamping body material is compatible with steel fastener contact before final assembly.
