Gibraltar 22720.0928 Ball End Clamping Screw M12 50mm

Product Description

The GIBRALTAR 22720.0928 is a headless ridged flat face ball end clamping screw designed for workholding and fixturing applications in industrial and machining environments. Constructed from steel throughout, including the ball and screw body, this fastener provides a maximum load capacity of 6,744 pounds. The M12 thread size and 50mm overall length make it suited for medium-duty clamping setups where a headless profile is required to keep a low-clearance or flush installation. Licensed machinists, tool and die makers, and fixture builders install this type of component in jigs, vises, and precision clamping assemblies.

This clamping screw is used in production machining and fabrication environments where repeatable workholding force is critical. The ridged flat face ball end allows for angular self-alignment against a workpiece without marring or slipping under load. It fits applications where a standard socket head or flanged screw would create interference. Typical installation scenarios include modular fixturing plates, manual vise assemblies, and custom jig builds in both job-shop and high-volume production settings.

Key Features

• Headless design provides a low-profile, flush installation for tight-clearance fixturing setups
• Ridged flat face ball end resists slipping and allows angular contact against workpiece surfaces
• Steel screw body and steel ball deliver a maximum load capacity of 6,744 pounds
• M12 thread size and 50mm overall length suit medium-duty clamping applications
• 6mm hex key drive allows installation and adjustment with standard Allen wrenches
• 8.5mm ball diameter provides consistent contact area under clamping load

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial workholding and fixturing assemblies requiring an M12 headless ball end clamping screw with a ridged flat face contact style.

Installation Notes

Installation is performed by machinists or fixture technicians using a 6mm hex key. Ensure the mating threaded hole is clean and free of debris before threading in the screw. De-energize or lock out any associated machinery before adjusting or replacing clamping components. Do not exceed the rated maximum load capacity of 6,744 pounds in service.
