Gibraltar 22720.0546 Headless Ball End Clamping Screw M4

Product Description

The GIBRALTAR 22720.0546 is a headless, plain flat face ball end clamping screw designed for precision workholding and fixturing applications. Manufactured from steel throughout, this set-screw-style fastener uses an M4 thread and accepts a 2.00 mm hex key for installation and adjustment. The ball end measures 2.50 mm in diameter and provides a self-aligning contact point against the workpiece, reducing marring while maintaining clamping force. Rated for a maximum load capacity of 786 pounds, this screw delivers reliable holding force in compact fixture assemblies where a low-profile, headless design is required.

This clamping screw is suited for use in modular fixturing systems, tooling plates, vise jaws, and precision machine tool accessories found in manufacturing and metalworking environments. The flat face ball end style is commonly specified where point contact with the workpiece must be maintained at slight angular offsets without damaging the clamped surface. Machinists, toolmakers, and fixture builders will encounter this style in both production and prototype fixturing setups.

Key Features

• Headless design sits flush with or below the fixture surface to avoid interference
• Plain flat face ball end provides self-aligning contact and reduces workpiece marring
• M4 thread with 2.00 mm hex key drive for easy installation in tight spaces
• 786-pound maximum load capacity for secure clamping in demanding fixturing applications
• All-steel construction, both screw body and ball, for durability and wear resistance
• 15.60 mm overall length suits compact fixture and tooling plate applications

Compatibility

Designed as an OEM-style replacement or direct-specification component for M4-threaded workholding fixtures, tooling plates, and modular fixturing systems requiring a headless ball end clamping screw.

Installation Notes

Installation requires a 2.00 mm hex key; use a calibrated torque wrench or T-handle to avoid overdriving the M4 thread in aluminum or softer fixture bodies. Ensure the mating threaded hole is clean and free of chips before installation. Do not exceed the rated 786-pound load capacity. Machinists and toolmakers performing fixture assembly should verify thread engagement depth meets the fixture manufacturer's specification before applying clamping load.
