Gibraltar 22720.0046 Rolling Ball Clamping Screw 16mm Steel

Product Description

The GIBRALTAR 22720.0046 is a headless rolling ball end clamping screw designed for precision workholding and fixture applications. Manufactured from steel with a steel rolling ball end, this screw provides consistent clamping force with a maximum load capacity of 786 pounds. The headless design allows the fastener to sit flush or below the surface of a workpiece, making it well suited for low-profile fixturing setups. The rolling ball end reduces friction and allows for slight angular misalignment during clamping, improving contact and load distribution. At 16mm overall length with a 2.5mm ball diameter, it fits compact fixture blocks and modular workholding systems where space is limited.

This clamping screw is used in manufacturing, machining, and industrial fixture applications where controlled, repeatable clamping force is needed. It is commonly installed in drill jigs, modular fixturing plates, and precision tooling setups found in job shops, production machining environments, and assembly fixtures. The rolling ball end makes it particularly effective in applications where the clamping surface is not perfectly perpendicular to the screw axis. Installation is typically performed by machinists, toolmakers, or fixture builders working with standard threaded fixture components.

Key Features

• Headless design allows flush or sub-flush installation in fixturing blocks and jig plates
• Rolling ball end accommodates slight angular misalignment and reduces surface marring
• 786 pound maximum load capacity for reliable clamping force in production environments
• 2.5mm ball diameter provides consistent point contact on workpieces
• All-steel construction — screw body and ball — for durability in shop environments
• 16mm overall length suits compact fixture and tooling block applications

Compatibility

Designed as an OEM-style replacement or direct-use component for standard threaded workholding fixtures and modular tooling systems that accept headless clamping screws of this thread size and overall length.

Installation Notes

Installation is typically performed by toolmakers or machinists using a hex key or appropriate driver for the headless drive socket. Ensure the mating threaded bore is clean and free of debris before installation. Do not exceed the rated maximum load capacity of 786 pounds during clamping operations. Inspect the rolling ball end for free rotation before placing the screw in service to confirm proper function.
