Gibraltar 22720.0544 Ball End Clamping Screw M4 Steel

Product Description

The GIBRALTAR 22720.0544 is a headless, plain flat face, ball end clamping screw designed for precision workholding and fixturing applications. Machined from steel with a steel ball, this screw accepts an M4 thread and measures 9.6 millimeters in overall length. The 2.5-millimeter ball diameter and flat face design allow for point contact clamping without marring or shifting the workpiece. Rated for a maximum load capacity of 786 pounds, it delivers reliable holding force in demanding setups. A 2-millimeter hex key drives the headless body, keeping the profile flush with the surrounding fixture surface.

This clamping screw is suited for use in machine tool fixtures, jigs, vises, and modular workholding systems found in production machining and toolroom environments. Machinists, toolmakers, and fixture designers install these screws where a compact, low-profile clamping element is required. The headless configuration allows installation in counterbored or recessed locations where a headed fastener would interfere with the workpiece or adjacent components.

Key Features

• M4 thread size for compatibility with standard metric fixture components
• 9.6-millimeter overall length suits compact and recessed mounting locations
• 786-pound maximum load capacity for reliable clamping force
• 2.5-millimeter steel ball with plain flat face contact surface
• Headless body driven by a 2-millimeter hex key, maintaining a flush profile
• Steel construction throughout for durability in industrial environments

Compatibility

Designed as a metric M4 replacement or upgrade clamping screw for standard modular fixturing systems, jig plates, and workholding assemblies that accept headless ball end clamping elements.

Installation Notes

Installation is typically performed by machinists or toolmakers using a 2-millimeter hex key. Ensure the mating threaded hole is clean and free of chips or debris before threading the screw into position. Do not exceed the rated maximum load capacity during clamping operations. Confirm the workpiece seating and alignment before applying final clamping force.
