Gibraltar 22720.0581 Ball End Clamping Screw M8 Steel

Product Description

The GIBRALTAR 22720.0581 is a headless, plain flat face ball end clamping screw designed for workholding and fixturing applications. Manufactured from steel throughout, this set-style clamping screw features an M8 thread and a 10mm overall length. The 5.5mm ball diameter contacts the workpiece with a flat face to distribute clamping load without marring, supporting a maximum load capacity of 3,272 pounds. A 4mm hex key drive allows precise torque application in tight fixture assemblies. Licensed machinists, toolmakers, and fixture builders typically specify this component in production and precision machining environments.

This clamping screw is suited for use in modular fixturing systems, vise assemblies, clamp bodies, and custom workholding fixtures found in machine shops and manufacturing facilities. Its compact 10mm overall length makes it appropriate for space-constrained clamping locations where a standard-length screw would interfere with adjacent components or toolpaths. The headless design allows the screw to sit flush or below the surface of the clamping body when fully engaged.

Key Features

• Headless design sits flush within clamping body to eliminate interference
• Plain flat face ball end distributes clamping force and reduces workpiece marking
• M8 thread size for broad compatibility with standard metric fixturing components
• Maximum load capacity of 3,272 pounds for reliable clamping in production applications
• 4mm hex key drive for precise engagement in confined spaces
• Full steel construction on both screw body and ball for durability

Compatibility

Designed as a direct-fit replacement or spare for standard M8 metric workholding and fixturing assemblies requiring a headless ball end clamping screw with a 10mm overall length.

Installation Notes

Installation is performed by toolmakers or machinist technicians using a 4mm hex key. Ensure the mating threaded hole is clean and free of debris before threading in the screw. Do not exceed the rated maximum load capacity during clamping operations. Verify thread engagement depth is sufficient for the load applied before securing the workpiece.
