Gibraltar 22720.0123 Headless Rolling Ball Clamping Screw

Product Description

The GIBRALTAR 22720.0123 is a headless rolling ball end clamping screw designed for precision fixturing and workholding applications. Manufactured from steel throughout — both the screw body and the ball end — it delivers a maximum load capacity of 6,744 pounds in a compact 27mm overall length. The rolling ball end allows the fastener to make positive contact against irregular or angled surfaces without binding, maintaining consistent clamping force. This type of screw is typically installed by machinists, toolmakers, and fixture builders working in production or job-shop environments.

This clamping screw suits applications where a flush or low-profile fastener head is required and surface contact must be maintained under load. The headless design keeps the fastener below or flush with the workpiece surface, making it appropriate for use in jig plates, vise jaws, modular fixturing systems, and machine tool setups. Its steel construction supports use in both light and heavy-duty clamping scenarios within metalworking and industrial assembly environments.

Key Features

• Headless design sits flush with or below the mating surface for clearance-sensitive setups
• Rolling ball end maintains consistent contact on angled or uneven clamping surfaces
• 6,744 lb maximum load capacity for heavy-duty fixturing demands
• 27mm overall length in a compact form factor
• All-steel construction — screw body and ball material both steel

Compatibility

Designed as an OEM-style or replacement clamping screw for standard industrial fixturing systems and modular workholding assemblies that accept headless rolling ball end fasteners of matching thread and overall length specifications.

Installation Notes

Installation is typically performed by machinists or toolmakers using standard hex key or Allen wrench tooling appropriate for the drive size. Always confirm thread engagement depth and mating thread condition before applying load. Do not exceed the rated 6,744 lb maximum load capacity. Verify that the ball end seats cleanly against the clamping surface before torquing to avoid point-load damage to the workpiece.
