Gibraltar 22720.0621 Ball End Clamping Screw M12 Steel

Product Description

The GIBRALTAR 22720.0621 is a headless, plain flat face ball end clamping screw designed for use in workholding, fixturing, and tooling applications. The screw features an M12 thread size and measures 16mm in overall length. The plain flat face ball end design allows the screw to apply clamping force against workpieces at varying angles without marring surfaces. It is actuated using a 6mm hex key and is manufactured from steel throughout, including the 8.5mm diameter ball end. With a maximum load capacity of 6,744 pounds, this screw is suited for demanding fixturing environments where secure, repeatable clamping is required.

This clamping screw is used in machine tool fixtures, vises, jigs, and modular workholding systems where a headless profile is preferred to keep the fastener below the clamping surface. The M12 thread size makes it compatible with standard metric fixturing components. Typical installers include machinists, toolmakers, and fixture designers working in manufacturing and precision machining environments. It is sold individually and is appropriate for both original equipment assembly and field replacement of worn or damaged clamping screws.

Key Features

• Headless design keeps the screw profile flush or below the fixture surface
• Plain flat face ball end accommodates angular clamping without surface damage
• M12 thread size for compatibility with standard metric fixturing hardware
• 6,744 lb maximum load capacity for high-force workholding applications
• 8.5mm ball diameter for consistent contact area under load
• Steel construction throughout for durability in shop environments

Compatibility

Designed as a direct-fit replacement or new-build component for metric workholding fixtures, jigs, and tooling assemblies using M12 threaded clamping screw positions.

Installation Notes

Installation is performed using a 6mm hex key. Ensure the mating threaded bore is clean and free of debris before installation. Thread engagement should be sufficient to support the rated load without bottoming the screw. Follow applicable shop safety and lockout procedures before servicing or replacing clamping hardware on powered machinery.
