Gibraltar 22720.0066 Headless Rolling Ball Clamping Screw M6

Product Description

The GIBRALTAR 22720.0066 is a headless rolling ball end clamping screw designed for precision workholding and fixturing applications. Threaded M6 with an overall length of 25.8mm, this screw features a 4mm rolling ball tip that allows the clamped surface to pivot slightly under load, reducing point stress and maintaining even contact. Maximum rated load capacity is 2,023 pounds. The hex socket drive accepts a 3mm hex key for installation and adjustment. Both the screw body and ball are manufactured from steel. This fastener is installed by machinists, toolmakers, and fixture builders working in CNC, manual machining, and assembly environments.

This clamping screw is suited for use in jigs, fixtures, vises, and workholding setups where a positive, low-profile clamping point is required. The rolling ball end accommodates slight angular misalignment between the screw tip and the clamped workpiece, making it well suited for production fixtures where repeated part loading is required. It is commonly used in machine shops, tool rooms, and manufacturing assembly fixtures.

Key Features

• Headless design keeps the screw profile flush or below the fixture surface
• Rolling ball tip allows angular float to reduce stress concentration on clamped surfaces
• M6 thread size for compatibility with standard metric fixture components
• 2,023 lb maximum load capacity for reliable clamping force
• 3mm hex key drive for easy installation and torque adjustment
• Steel screw body and steel ball for durability in machine shop environments

Compatibility

Designed as a direct-fit replacement or addition for standard M6 metric workholding fixtures, jigs, and clamping assemblies that accept headless ball-end clamping screws.

Installation Notes

Installation is performed by machinists or fixture builders using a 3mm hex key. Ensure the mating threaded hole is clean and free of chips or debris before threading in the screw. Do not exceed the rated load capacity of 2,023 lb. Verify thread engagement depth is sufficient for the load demands of the application before putting the fixture into service.
