Gibraltar 22720.0628 Ball End Clamping Screw M12 50mm

Product Description

The GIBRALTAR 22720.0628 is a headless ball end clamping screw designed for workholding and fixture applications in machining and manufacturing environments. The screw features a plain flat face ball end that transmits clamping force without marring workpiece surfaces. Made from steel throughout, this M12-threaded screw measures 50mm in overall length and accepts a 6mm hex key for installation. It is rated for a maximum load capacity of 6,744 pounds, making it suitable for demanding fixturing and clamping setups. Machinists, toolmakers, and fixture builders install this type of screw in jigs, fixtures, and vises where precise, repeatable clamping pressure is required.

This clamping screw is used in industrial workholding fixtures, modular fixturing systems, and machine tool setups where a headless profile is necessary to avoid interference with workpieces or fixture components. The M12 thread size and 50mm overall length suit a wide range of standard fixture plates and clamping blocks. The plain flat face ball end allows for angular compensation while maintaining consistent contact force against a workpiece or clamping pad.

Key Features

• M12 thread size for compatibility with standard metric fixturing components
• 50mm overall length for versatile reach in clamping assemblies
• 6,744 pound maximum load capacity for heavy-duty workholding
• Plain flat face ball end allows angular compensation without marring surfaces
• Headless design eliminates head interference in tight fixture clearances
• Steel construction on both screw body and ball for durability under load

Compatibility

Designed as a standard metric replacement or direct-use clamping screw for M12-threaded workholding fixtures, jig plates, and modular fixturing systems requiring a headless ball end configuration.

Installation Notes

Installation is performed with a 6mm hex key. Ensure the mating threaded fixture block or plate is clean and free of debris before threading in the screw. Verify load requirements do not exceed the rated maximum capacity before applying clamping force. Periodic inspection of the ball end and threaded shank is recommended in high-cycle fixturing applications.
