Gibraltar 22720.0065 Headless Rolling Ball End Clamping Screw

Product Description

The GIBRALTAR 22720.0065 is a headless rolling ball end clamping screw designed for precision clamping and positioning applications in machining, fixturing, and workholding setups. This screw features a freely rotating 4mm steel ball at the tip that distributes clamping force evenly against a workpiece surface, reducing marking and allowing smooth rotational contact under load. The M6 thread and 3mm hex key drive make it compatible with standard tooling. Rated to a maximum load capacity of 2,023 pounds, it is suited for moderate-duty clamping tasks. The headless design allows the screw to sit flush or below the surface of a threaded hole, keeping the profile low in tight fixture arrangements. Typically installed by machinists, toolmakers, and fixture builders.

This clamping screw is used in machine shop fixturing, jig and fixture plates, vise stops, modular workholding systems, and tooling plates where a low-profile, adjustable clamping point is required. The rolling ball tip is particularly well suited for applications where the clamped surface must remain unmarked or where the clamp point experiences slight angular misalignment. Suitable for both production and prototype fixturing environments.

Key Features

• Headless design keeps profile flush or below the mounting surface in fixture assemblies
• Freely rolling 4mm steel ball tip distributes load and reduces workpiece marking
• M6 thread size with 3mm hex key drive for precise torque adjustment
• 2,023-pound maximum load capacity for moderate-duty clamping
• All-steel construction for durability in industrial shop environments
• 20.8mm overall length suitable for standard fixture plate thread depths

Compatibility

Designed as an OEM-style replacement or direct-use component for M6-threaded fixture plates, jig bodies, and modular workholding systems requiring a headless rolling ball end clamping screw.

Installation Notes

Installation is performed by machinists or toolmakers using a 3mm hex key into any M6-threaded hole of appropriate depth. Ensure the receiving thread is clean and free of chips before installation. Do not exceed the rated maximum load capacity of 2,023 pounds. Confirm thread engagement depth is sufficient to prevent stripping under clamping loads.
