Gibraltar 22720.0064 Rolling Ball Clamping Screw M6

Product Description

The GIBRALTAR 22720.0064 is a headless rolling ball end clamping screw designed for precision fixturing, tooling, and workholding applications. Threaded M6 with an overall length of 16.8mm, this screw accepts a 3mm hex key for drive engagement and delivers a maximum load capacity of 2,023 pounds through its 4mm rolling steel ball end. The rolling ball design allows the clamping face to self-align against angled or irregular workpiece surfaces, distributing load evenly without marring. Both the screw body and ball are constructed from steel for durability under repeated clamping cycles. Machinists, toolmakers, and fixture builders typically install this component as part of modular or custom clamping assemblies.

This clamping screw is suited for use in machine tool fixtures, jig plates, modular fixturing systems, and precision workholding setups found in CNC machining centers, manual mills, and grinding operations. Its compact 16.8mm length makes it appropriate for low-profile fixture designs where standard-length screws would interfere with toolpaths or adjacent clamp elements. The headless configuration allows the screw to sit flush or below a fixture plate surface when fully engaged, keeping the work envelope clear.

Key Features

• Rolling ball end self-aligns against angled or uneven clamping surfaces
• M6 thread size for compatibility with standard metric fixturing hardware
• 2,023 lb maximum load capacity for reliable clamping force
• Headless design allows flush or sub-surface installation in fixture plates
• 3mm hex key drive for precise torque application in tight spaces
• Steel screw body and steel ball for consistent performance under cyclic loading

Compatibility

Designed as a standard M6 metric clamping screw for use in modular fixturing systems, jig plates, and precision workholding assemblies that accept M6 threaded clamping components.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a 3mm hex key. Ensure the mating threaded hole is clean and free of chips or debris before installation. Do not exceed the rated maximum load capacity of 2,023 lb during clamping operations. Always verify that the fixture plate or receiver block thread condition is sound before applying clamping force.
