Gibraltar 22720.0043 Headless Rolling Ball Clamping Screw M4

Product Description

The GIBRALTAR 22720.0043 is a headless rolling ball end clamping screw designed for precision workholding and fixturing applications. Built from steel throughout, this set screw features a 2.5mm rolling ball tip that allows the fastener to apply consistent clamping force even when the mating surface is not perfectly perpendicular. With an M4 thread size, an overall length of 8mm, and a maximum load capacity of 786 pounds, it delivers reliable holding force in a compact form factor. A 2mm hex key is required for installation. Machinists, tool and die technicians, and fixture builders are the typical installers.

This clamping screw is suited for use in machine tool fixtures, jigs, workholding clamps, and precision assembly applications where a low-profile fastener with a self-aligning contact point is required. The rolling ball end reduces point-load stress on the clamped workpiece surface, making it appropriate for use against finished or semi-finished parts. Single-piece packaging makes it easy to source as a direct replacement or an individual addition to a fixturing setup.

Key Features

• Headless set screw design keeps the fastener flush or below the surface for low-profile clamping
• Rolling ball tip self-aligns to angled or uneven clamping surfaces, distributing contact load
• 786-pound maximum load capacity in a compact 8mm overall length
• Full steel construction on both screw body and ball for durability in shop environments
• M4 thread size with 2mm hex key drive for standard tooling compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit addition for M4-threaded fixturing components, workholding clamps, and precision jig assemblies that require a headless rolling ball end clamping screw.

Installation Notes

Installation is performed by machinists or fixture technicians using a standard 2mm hex key. Ensure the receiving threaded hole is clean and free of debris before threading in the screw. De-energize or secure any machinery before servicing fixtures or clamping components. Do not exceed the rated maximum load capacity of 786 pounds.
