Gibraltar 22720.0543 Headless Ball End Clamping Screw M4

Product Description

The GIBRALTAR 22720.0543 is a headless, plain flat face ball end clamping screw designed for precision workholding and fixturing applications. Manufactured from steel throughout, this set screw features an M4 thread with a 7.6mm overall length and a 2.5mm ball diameter at the contact face. The flat face ball end design allows secure, low-profile clamping without a protruding head, making it well-suited for tight fixture configurations. With a maximum load capacity of 786 pounds, it delivers reliable holding force in demanding setups. A 2.0mm hex key drives the screw for controlled torque application during installation.

This clamping screw is used in tooling, fixturing, jigs, and workholding assemblies common in machining and fabrication environments. The headless profile allows flush or sub-flush seating in threaded fixture blocks, clamp bodies, and modular tooling plates. The plain flat face ball end provides a pivot-style contact point that accommodates slight angular misalignment while maintaining consistent clamping load. Trade professionals, toolmakers, and fixture builders working with M4-threaded components will find this screw a direct-fit solution for standard set screw positions in their assemblies.

Key Features

• Headless design seats flush with or below the workpiece surface, eliminating snag points
• Plain flat face ball end allows slight angular adjustment at the contact interface
• M4 thread size for compatibility with standard metric fixture hardware
• 786-pound maximum load capacity for secure holding in production fixturing
• 2.0mm hex key drive for precise, controlled tightening in confined spaces
• Full steel construction for durability in machine shop environments

Compatibility

Designed as a standard M4 metric set screw replacement or new-installation fastener for workholding fixtures, jigs, clamp bodies, and modular tooling assemblies that use headless ball end clamping screws.

Installation Notes

Installation requires a 2.0mm hex key; use a calibrated torque driver where load-sensitive fixturing demands consistent clamping force. Ensure the mating threaded bore is clean and free of chips or debris before threading the screw in by hand. Do not exceed the rated 786-pound maximum load capacity. Follow applicable facility and machine tool safety protocols when servicing or adjusting workholding components under load.
