Gibraltar 22720.0555 Headless Ball End Clamping Screw M5

Product Description

The GIBRALTAR 22720.0555 is a headless, plain flat face ball end clamping screw engineered for precision workholding and fixturing applications. Manufactured from steel, this set-screw-style fastener features an M5 thread and measures 15.5 millimeters in overall length. The 3 millimeter ball end transmits clamping force through a flat face contact point, allowing secure, low-profile engagement against workpieces or fixture components. Driven with a 2.5 millimeter hex key, it is rated for a maximum load capacity of 1,011 pounds. Machinists, toolmakers, and fixture builders install this type of fastener where a protruding head would interfere with adjacent components or travel paths.

This clamping screw is suited for use in jigs, fixtures, vises, and toolholding assemblies across machine shops, production floors, and fabrication environments. Its headless profile keeps it flush or below the workpiece surface, making it appropriate for tight-clearance installations. The plain flat face ball style provides consistent contact and is a common choice in modular fixturing systems where repeatable clamping force is required. Installation is performed by qualified machinists or toolmakers as part of fixture setup or maintenance.

Key Features

• Headless design for flush or sub-flush installation in fixturing and workholding applications
• Plain flat face ball end provides consistent, repeatable clamping contact
• M5 thread size with 2.5 mm hex key drive for controlled installation torque
• 1,011 pound maximum load capacity for reliable clamping force retention
• Steel construction on both screw body and ball for durability in shop environments
• 15.5 mm overall length suits standard fixture block and tooling plate depths

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for M5-threaded clamping screw positions in jigs, fixtures, and modular workholding systems requiring a headless ball end style.

Installation Notes

Installation is performed by a machinist or toolmaker using a 2.5 mm hex key. Ensure the receiving threaded bore is clean and free of chips or debris before installation. Do not exceed the rated maximum load capacity of 1,011 pounds. Always de-energize and secure any machine or fixture assembly before servicing clamping components.
